portal and does not permanently store telemetry. It is a vendor-neutral combination of specifications, APIs, SDKs, instrumentation, the OpenTelemetry Protocol (OTLP), and the Collector. Applications use it to generate, process, and export data; search, storage, permissions, and alerting remain the responsibility of the chosen backend. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">The three <strong style=\"font-weight:700;color:inherit\">Signals<\/strong> answer various operational questions. Traces organize the individual steps of a request chronologically and logically; metrics aggregate states into time series; and logs record individual events. A robust observability practice combines all three: a trace pinpoints an anomalous request, metrics show its frequency over time, and associated logs provide error messages or additional details.  <\/p>\n<div class=\"wh-table-scroll\" tabindex=\"0\" role=\"region\" aria-label=\"Indicators of Common Operational Issues\" style=\"width:100%;max-width:100%;overflow-x:auto;margin:28px 0;border:1px solid #dce5e9;border-radius:14px;background:#fff;box-shadow:0 10px 28px -16px rgba(24,47,60,.32);box-sizing:border-box\"><table style=\"width:100%;min-width:580px;border-collapse:separate;border-spacing:0;border:0;margin:0;font-size:15px;line-height:1.6;background:#fff\"><caption style=\"padding:20px;text-align:start;font-size:17px;line-height:1.5;font-weight:700;color:#173246;background:#fff\">Indicators of Common Operational Issues<\/caption><thead><tr><th scope=\"col\" style=\"padding:15px 18px;border:0;border-bottom:1px solid #e2e9ed;text-align:start;vertical-align:top;white-space:normal;font-size:15px;line-height:1.6;background:#19394d;color:#fff\">Signal<\/th><th scope=\"col\" style=\"padding:15px 18px;border:0;border-bottom:1px solid #e2e9ed;text-align:start;vertical-align:top;white-space:normal;font-size:15px;line-height:1.6;background:#19394d;color:#fff\">Typical operational question<\/th><th scope=\"col\" style=\"padding:15px 18px;border:0;border-bottom:1px solid #e2e9ed;text-align:start;vertical-align:top;white-space:normal;font-size:15px;line-height:1.6;background:#19394d;color:#fff\">Limits of Validity<\/th><\/tr><\/thead><tbody><tr><td style=\"padding:15px 18px;border:0;border-bottom:1px solid #e2e9ed;text-align:start;vertical-align:top;white-space:normal;font-size:15px;line-height:1.6;background:#fff;color:#294252\">Traces<\/td><td style=\"padding:15px 18px;border:0;border-bottom:1px solid #e2e9ed;text-align:start;vertical-align:top;white-space:normal;font-size:15px;line-height:1.6;background:#fff;color:#294252\">Where did a single request spend its time?<\/td><td style=\"padding:15px 18px;border:0;border-bottom:1px solid #e2e9ed;text-align:start;vertical-align:top;white-space:normal;font-size:15px;line-height:1.6;background:#fff;color:#294252\">They show the processes as they occur, but do not prove a cause.<\/td><\/tr><tr><td style=\"padding:15px 18px;border:0;border-bottom:1px solid #e2e9ed;text-align:start;vertical-align:top;white-space:normal;font-size:15px;line-height:1.6;background:#f4f7f9;color:#294252\">Metrics<\/td><td style=\"padding:15px 18px;border:0;border-bottom:1px solid #e2e9ed;text-align:start;vertical-align:top;white-space:normal;font-size:15px;line-height:1.6;background:#f4f7f9;color:#294252\">How do the error rate and latency distribution change over time?<\/td><td style=\"padding:15px 18px;border:0;border-bottom:1px solid #e2e9ed;text-align:start;vertical-align:top;white-space:normal;font-size:15px;line-height:1.6;background:#f4f7f9;color:#294252\">Aggregates do not automatically account for a single error.<\/td><\/tr><tr><td style=\"padding:15px 18px;border:0;border-bottom:1px solid #e2e9ed;text-align:start;vertical-align:top;white-space:normal;font-size:15px;line-height:1.6;background:#fff;color:#294252\">Logs<\/td><td style=\"padding:15px 18px;border:0;border-bottom:1px solid #e2e9ed;text-align:start;vertical-align:top;white-space:normal;font-size:15px;line-height:1.6;background:#fff;color:#294252\">Which detailed message is associated with a suspicious transaction?<\/td><td style=\"padding:15px 18px;border:0;border-bottom:1px solid #e2e9ed;text-align:start;vertical-align:top;white-space:normal;font-size:15px;line-height:1.6;background:#fff;color:#294252\">Without a trace ID and span ID, the ability to map data to a request is limited.<\/td><\/tr><\/tbody><\/table><\/div><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">For hosting platforms, this results in a clear division of labor: OTel standardizes the generation and sharing of telemetry, but does not replace any target system.

Only these decisions make the technical export paths and data volumes manageable. <\/p>\n<\/section><section class=\"wh-section\" aria-labelledby=\"trace-kontext-ueber-hostinggrenzen\" style=\"display:block;margin:0 0 36px;min-width:0\"><h2 id=\"trace-kontext-ueber-hostinggrenzen\" style=\"margin:38px 0 18px;color:#172f41;font-size:clamp(24px,1.25rem + 1vw,30px);font-weight:700;line-height:1.3;scroll-margin-top:115px\">Passing the trace context across hosting boundaries<\/h2><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">Distributed tracing links the steps of a logical transaction across process and network boundaries. A <strong style=\"font-weight:700;color:inherit\">Trace Context<\/strong> includes, among other things, a trace ID for the entire process and span IDs for individual operations. Spans can form parent-child relationships; together, they describe a directed acyclic graph of the observed work. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">With HTTP, this context is typically passed on according to the W3C Trace Context specification, particularly in the header <code data-no-translation style=\"font:600 .87em\/1.5 ui-monospace,monospace;color:#235063;background:#edf3f5;border-radius:4px;padding:.1em .3em\">traceparent<\/code>. A service takes over the incoming context and creates a corresponding span for its portion. For outgoing calls, it must pass the context along again. If this does not occur at a controllable transition point, the request is split into separate traces in the backend. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">During checkout, a reverse proxy can forward the request to the application. The application then checks a cache, queries the database, and calls a payment service and an email API. If the transitions are instrumented and the context is propagated, the sequence of these steps can be traced. The same principle applies to queue or background jobs, provided that the context is included with the message and restored at the consumer end. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">However, a long external HTTP span only shows the observed duration of this instrumented operation. It does not prove whether the cause was DNS, the network, retry attempts, the remote system, or load on the local system. Traces are therefore a starting point for diagnosis; determining the root cause requires appropriate metrics, logs, and a technical review of the components involved. <\/p>\n<\/section><section class=\"wh-section\" aria-labelledby=\"hostingmodelle-und-voraussetzungen\" style=\"display:block;margin:0 0 36px;min-width:0\"><h2 id=\"hostingmodelle-und-voraussetzungen\" style=\"margin:38px 0 18px;color:#172f41;font-size:clamp(24px,1.25rem + 1vw,30px);font-weight:700;line-height:1.3;scroll-margin-top:115px\">Hosting models determine OTel's scope of action<\/h2><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">Whether OpenTelemetry is feasible depends first and foremost on the hosting model.

network paths, and process environment yourself. The official examples list the following ports for local OTLP receivers: <code data-no-translation style=\"font:600 .87em\/1.5 ui-monospace,monospace;color:#235063;background:#edf3f5;border-radius:4px;padding:.1em .3em\">4317<\/code> for gRPC and <code data-no-translation style=\"font:600 .87em\/1.5 ui-monospace,monospace;color:#235063;background:#edf3f5;border-radius:4px;padding:.1em .3em\">4318<\/code> for HTTP. This does not imply a general recommendation to enable it: Production accessibility, firewall rules, and authentication must be tailored to the specific platform. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">In contrast, traditional shared hosting often lacks the necessary permissions for a permanently running collector or process injection for auto-instrumentation. Zero-code solutions exist for several language ecosystems, but their usability depends on runtime, deployment method, and platform approvals. Therefore, do not base your planning on the OTel feature, but rather on the permitted configuration and export methods of the specific hosting environment. <\/p>\n<\/section><section class=\"wh-section\" aria-labelledby=\"instrumentierung-und-dienstidentitaet\" style=\"display:block;margin:0 0 36px;min-width:0\"><h2 id=\"instrumentierung-und-dienstidentitaet\" style=\"margin:38px 0 18px;color:#172f41;font-size:clamp(24px,1.25rem + 1vw,30px);font-weight:700;line-height:1.3;scroll-margin-top:115px\">Planning Instrumentation and Service Identity in a Targeted Manner<\/h2><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">It all starts with a clear <strong style=\"font-weight:700;color:inherit\">Service Identity<\/strong>. Resources describe the entity that generates telemetry, such as a service or its runtime environment. Define the resource attributes used for this purpose in a controlled and consistent manner. Which specific attributes are automatically available or must be configured separately depends on the language implementation, instrumentation, and version. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">Next, check the zero-code or auto-instrumentation capabilities of the actual runtime language in use and its version. The OpenTelemetry documentation lists corresponding approaches for Java, JavaScript, .NET, PHP, Python, and Go, among others. They often capture HTTP, database, or client library boundaries, but the scope, maturity, and supported libraries vary by implementation. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">Automatically generated traces primarily show technical transitions. For business steps such as \u201eOrder approved\u201c or \u201eInvoice generated,\u201c you should add targeted instrumentation to the code, provided these steps are relevant to diagnostics. This makes it clear at which operation a process fails, without overloading every function call with telemetry. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">Additional resource attributes may include information about the host, process, container, or Kubernetes environment. Which attributes a language implementation sets automatically and which semantic conventions apply must be verified separately for each SDK, instrumentation, and version. The values should come from controlled deployment metadata so that the identification of the same execution environment remains traceable. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">In many customer projects, naming conventions are part of the client and deployment strategy. Telemetry must not inadvertently merge projects or facilitate access through shared attributes. The article on [...], also explains how application architecture, isolation, and scaling are interrelated. <a href=\"https:\/\/webhosting.de\/en\/saas-hosting-scaling-platforms-growth\/\">multi-tenant SaaS hosting<\/a>. With regard to telemetry itself: Collect customer-specific identifiers only if they are functionally necessary and have been reviewed for compliance with data protection laws.<\/p>\n<\/section><section class=\"wh-section\" aria-labelledby=\"collector-architekturen-und-sicherer-export\" style=\"display:block;margin:0 0 36px;min-width:0\"><h2 id=\"collector-architekturen-und-sicherer-export\" style=\"margin:38px 0 18px;color:#172f41;font-size:clamp(24px,1.25rem + 1vw,30px);font-weight:700;line-height:1.3;scroll-margin-top:115px\">Collector Architectures and Secure Export<\/h2><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">With direct export, each application sends its OTLP data directly to the selected backend.

This option is better suited for a small, clearly defined installation whose backend is securely accessible and that does not require central processing prior to export. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">A local <strong style=\"font-weight:700;color:inherit\">Collector<\/strong> For each host or pod, Telemetry collects data close to the application.

Baggage can propagate freely chosen key-value pairs across services and processes and make them available for traces, metrics, or logs. As a result, sensitive Baggage values may inadvertently reach downstream or external resources. Therefore, check its contents before any cross-service sharing. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">At <strong style=\"font-weight:700;color:inherit\">Luggage<\/strong> This scope is particularly important. Personal data, session IDs, passwords, or API keys do not belong here. A value that is not strictly necessary for business logic at every transition should not be included as baggage. Otherwise, automatic passing of the value in network calls increases the number of systems capable of processing it. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">Data minimization begins with instrumentation: Collect only the fields required for a specific diagnosis. Additionally, verify application- and library-specific trace attributes, log fields, URLs, headers, and database information using non-production sample data.

However, specific filter, attribute, or transform components differ in terms of distribution, signal support, and version status. Therefore, do not determine which component should process which fields until you have reviewed the intended release, and do not treat a general Collector description as approval for a specific configuration.  <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">When it comes to metrics, the team should determine in advance which attributes are truly needed for a specific operational question. Individual request or user identifiers, as well as full URLs, should not be included as dimensions merely as a precaution. Use representative sample data to verify which attribute values the instrumentation actually generates, and allow only the route, service, or error classes intended for defined analyses.<\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">Processing rules must be versioned and tested with representative, non-production sample data prior to rollout. This helps determine whether diagnostically necessary information is lost or whether sensitive values continue to be exported. Retention periods, authorization policies, access logs, and deletion policies are additional components of the selected backend\u2019s architecture and are not governed by OpenTelemetry itself. <\/p>\n<\/section><section class=\"wh-section\" aria-labelledby=\"betrieb-und-fehlersuche-im-collector\" style=\"display:block;margin:0 0 36px;min-width:0\"><h2 id=\"betrieb-und-fehlersuche-im-collector\" style=\"margin:38px 0 18px;color:#172f41;font-size:clamp(24px,1.25rem + 1vw,30px);font-weight:700;line-height:1.3;scroll-margin-top:115px\">Running Collector Stably and Troubleshooting Errors<\/h2><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">If traces are missing or an expected flow breaks down into multiple traces, start troubleshooting at the transition between services. First, check whether the outgoing request passes the context and whether the next service reads it. The W3C Trace Context with <code data-no-translation style=\"font:600 .87em\/1.5 ui-monospace,monospace;color:#235063;background:#edf3f5;border-radius:4px;padding:.1em .3em\">traceparent<\/code> Links only those components that actually support this sharing and do not override it. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">Next comes the pipeline: When the configured receiver receives data, does a processor allow the expected signals to pass through, and does the exporter reach its destination? Separate checks prevent a backend problem from being mistakenly identified as an instrumentation error. The collector\u2019s operational data and clearly defined test requests help pinpoint where losses occur at a specific stage. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">Export errors then require a check of DNS, reachability, certificates, and authentication. S14 recommends secure, authenticated channels for Collector connections and operation without root or administrator privileges, provided that the components used do not require additional privileges. However, the source documents the moving development branch <code data-no-translation style=\"font:600 .87em\/1.5 ui-monospace,monospace;color:#235063;background:#edf3f5;border-radius:4px;padding:.1em .3em\">main<\/code>; Therefore, before putting the system into production, verify that these safety instructions match the documentation and configuration of the specific Collector version being used. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">Another operational indicator is <strong style=\"font-weight:700;color:inherit\">Memory Pressure<\/strong>. Queues, retry attempts, and complex processing can consume memory if a target system responds slowly or fails. Memory limits and queue sizes must be appropriate for the load and failure behavior; their impact is verified before the system goes into production. The absence of limits can destabilize the collector itself. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">Therefore, application traces aren't the only factor to consider when diagnosing issues. Also monitor rejected or discarded data, queues, export errors, and the collector's resources. Make changes incrementally: start with a single pipeline or service, then check the impact on completeness and storage. This makes it clear which configuration change has improved or worsened a set of errors. <\/p>\n<\/section><section class=\"wh-section\" aria-labelledby=\"architekturentscheidung-fuer-plattformteams\" style=\"display:block;margin:0 0 36px;min-width:0\"><h2 id=\"architekturentscheidung-fuer-plattformteams\" style=\"margin:38px 0 18px;color:#172f41;font-size:clamp(24px,1.25rem + 1vw,30px);font-weight:700;line-height:1.3;scroll-margin-top:115px\">Making Architecture Decisions for Platform Teams<\/h2><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">For a small, clearly defined application, direct export to the backend may be sufficient if access credentials, network paths, and data rules are handled securely. When dealing with multiple services, a local collector per host or an agent-based pattern is a possible architecture, but not a general best practice. S10 describes a separately operated collector on the host for Linux; pod, agent, and gateway variants should be evaluated based on the deployment patterns and the respective platform requirements.  <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">Growing platforms often benefit from a separation of tasks. Local collectors can receive and aggregate data; a central gateway collector can handle routing, uniform filtering, and the integration of multiple backends. However, this division creates an additional service whose availability, capacity, and access protection must be planned. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">In many customer projects, the separation of telemetry is a deliberate architectural decision. If projects require different access scopes, export destinations, backend permissions, and resource labels must be planned and verified accordingly. Freely defined attributes are used to describe telemetry; this article does not treat them as a substitute for technically enforced access control.<\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">Distributed dependencies such as caches, queues, and databases increase the need for diagnostics, but they are not a reason for blanket, comprehensive logging. In a Redis cluster in particular, individual services and background processors may see different parts of a workflow. The article on <a href=\"https:\/\/webhosting.de\/en\/redis-cluster-sharding-hosting-load-balancing\/\">Redis Cluster Sharding for Large Hosting Platforms<\/a> classifies the architecture of such a cache layer; for telemetry, it remains crucial to deliberately control context boundaries and data volume.<\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">The decision therefore combines <strong style=\"font-weight:700;color:inherit\">Backend Independence<\/strong> with actual operational overhead. A collector simplifies the process of switching between or providing parallel data feeds to targets, but it does not replace capacity planning or error handling. Platform teams should define which data each target receives, who has access, and which export failures must not impact the applications. <\/p>\n<p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">A phased rollout begins with a single service and a few transitions that are critical for diagnostics. Context continuity, filter rules, export stability, and memory behavior are then tested under representative load conditions. Only once these criteria have been verifiably met are additional languages, clients, or backends added. This limits risk and prevents the creation of a large pipeline without clear accountability. <\/p>\n<\/section><section class=\"wh-sources\" style=\"margin:40px 0 0;padding:24px 0 0;border-top:1px solid #dce5e9;color:#596b7b;font-size:14px;line-height:1.65\"><h2 style=\"margin:38px 0 18px;color:#172f41;font-size:clamp(24px,1.25rem + 1vw,30px);font-weight:700;line-height:1.3;scroll-margin-top:115px\">Sources and Current State of Knowledge<\/h2><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">Status of the research: <time datetime=\"2026-10-31\">2026-10-31<\/time><\/p><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\">Research date: October 31, 2026. The article clearly distinguishes between OpenTelemetry specifications, SDKs, collector components, and backends. S12 and S14 refer to the \u201cmain\u201d moving development branches and do not constitute evidence of a specific stable release. The \u201cmain\u201d status of S12, as verified on the research date, describes the tail sampling processor as beta for traces and documents stateful processing as well as additional, configurable options such as `sampling_strategy`, maximum_trace_size_bytes, internal shards, and an experimental tail_storage extension. These details are provided solely as reference points; prior to release or deployment, the Collector-Contrib version and distribution must be specified, and all statements must be reconciled with their version-specific documentation. This applies in particular to memory behavior, routing of all spans in a trace, default values, feature gates, sharding combinations, and resource requirements. For S14, the re-evaluation focuses specifically on secure, authenticated connections and minimized process privileges.<\/p><div class=\"wh-source-urls\"><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\"><span class=\"wh-source-url\" data-no-translation dir=\"ltr\" style=\"overflow-wrap:anywhere;font:12px\/1.6 ui-monospace,monospace;direction:ltr\">https:\/\/opentelemetry.io\/docs\/<\/span><\/p><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\"><span class=\"wh-source-url\" data-no-translation dir=\"ltr\" style=\"overflow-wrap:anywhere;font:12px\/1.6 ui-monospace,monospace;direction:ltr\">https:\/\/opentelemetry.io\/docs\/collector\/deploy\/<\/span><\/p><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\"><span class=\"wh-source-url\" data-no-translation dir=\"ltr\" style=\"overflow-wrap:anywhere;font:12px\/1.6 ui-monospace,monospace;direction:ltr\">https:\/\/opentelemetry.io\/docs\/specs\/otel\/overview\/<\/span><\/p><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\"><span class=\"wh-source-url\" data-no-translation dir=\"ltr\" style=\"overflow-wrap:anywhere;font:12px\/1.6 ui-monospace,monospace;direction:ltr\">https:\/\/opentelemetry.io\/docs\/specs\/otel\/logs\/<\/span><\/p><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\"><span class=\"wh-source-url\" data-no-translation dir=\"ltr\" style=\"overflow-wrap:anywhere;font:12px\/1.6 ui-monospace,monospace;direction:ltr\">https:\/\/opentelemetry.io\/docs\/concepts\/context-propagation\/<\/span><\/p><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\"><span class=\"wh-source-url\" data-no-translation dir=\"ltr\" style=\"overflow-wrap:anywhere;font:12px\/1.6 ui-monospace,monospace;direction:ltr\">https:\/\/opentelemetry.io\/docs\/concepts\/instrumentation\/<\/span><\/p><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\"><span class=\"wh-source-url\" data-no-translation dir=\"ltr\" style=\"overflow-wrap:anywhere;font:12px\/1.6 ui-monospace,monospace;direction:ltr\">https:\/\/opentelemetry.io\/docs\/languages\/sdk-configuration\/<\/span><\/p><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\"><span class=\"wh-source-url\" data-no-translation dir=\"ltr\" style=\"overflow-wrap:anywhere;font:12px\/1.6 ui-monospace,monospace;direction:ltr\">https:\/\/opentelemetry.io\/docs\/collector\/quick-start\/<\/span><\/p><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\"><span class=\"wh-source-url\" data-no-translation dir=\"ltr\" style=\"overflow-wrap:anywhere;font:12px\/1.6 ui-monospace,monospace;direction:ltr\">https:\/\/opentelemetry.io\/docs\/languages\/<\/span><\/p><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\"><span class=\"wh-source-url\" data-no-translation dir=\"ltr\" style=\"overflow-wrap:anywhere;font:12px\/1.6 ui-monospace,monospace;direction:ltr\">https:\/\/opentelemetry.io\/docs\/platforms\/linux\/configuration\/<\/span><\/p><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\"><span class=\"wh-source-url\" data-no-translation dir=\"ltr\" style=\"overflow-wrap:anywhere;font:12px\/1.6 ui-monospace,monospace;direction:ltr\">https:\/\/github.com\/open-telemetry\/opentelemetry-collector\/blob\/main\/docs\/security-best-practices.md<\/span><\/p><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\"><span class=\"wh-source-url\" data-no-translation dir=\"ltr\" style=\"overflow-wrap:anywhere;font:12px\/1.6 ui-monospace,monospace;direction:ltr\">https:\/\/opentelemetry.io\/docs\/languages\/go\/sampling\/<\/span><\/p><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\"><span class=\"wh-source-url\" data-no-translation dir=\"ltr\" style=\"overflow-wrap:anywhere;font:12px\/1.6 ui-monospace,monospace;direction:ltr\">https:\/\/github.com\/open-telemetry\/opentelemetry-collector-contrib\/blob\/main\/processor\/tailsamplingprocessor\/README.md<\/span><\/p><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\"><span class=\"wh-source-url\" data-no-translation dir=\"ltr\" style=\"overflow-wrap:anywhere;font:12px\/1.6 ui-monospace,monospace;direction:ltr\">https:\/\/opentelemetry.io\/docs\/concepts\/signals\/baggage\/<\/span><\/p><p style=\"margin:0 0 1.1em;font-size:inherit;line-height:inherit\"><span class=\"wh-source-url\" data-no-translation dir=\"ltr\" style=\"overflow-wrap:anywhere;font:12px\/1.6 ui-monospace,monospace;direction:ltr\">https:\/\/opentelemetry.io\/docs\/collector\/troubleshooting\/<\/span><\/p><\/div><\/section><\/div>","protected":false},"excerpt":{"rendered":"<p>OpenTelemetry connects traces, metrics, and logs across hosting boundaries.
