--- title: "Application Observability service overview | Grafana Cloud documentation" description: "Ready-made observability insights for a service" --- > For a curated documentation index, see [llms.txt](/llms.txt). For the complete documentation index, see [llms-full.txt](/llms-full.txt). # Application Observability service overview The overview page provides a health overview for a service with RED metrics (Request rates, Errors, and Duration) for: - The service as a whole - Related inbound and outbound services - Operations performed on the service Navigate to various child tabs and pages to uncover further details: - View **Traces** and **Logs** - View the service in the **Service map** - View RED metrics for each **Operation** - View **Runtime** specific performance metrics - On most panels, click **Explore** to view the queries used Un-instrumented services display limited metrics, from what the plugin is able to discover. ## Header Like other Application Observability pages, the service overview page has a header with a title, sub-tabs to navigate to, an action bar to change the data source and time-related filters and refresh intervals, and an environment selector. The header on the service overview page also includes technology icons, alongside the service name, with contextual menus. ### Technology icons Application Observability can show the following icons alongside a service name: - Technology icon, inferred from `telemetry.sdk.language` of the trace span - Kubernetes icon, if the service is using Kubernetes - Cloud icon, for services deployed on a cloud environment If the service uses Kubernetes, hover over the **Kubernetes icon** to view the environment labels and navigate to [Kubernetes monitoring](/docs/grafana-cloud/monitor-infrastructure/kubernetes-monitoring/). For services deployed on a cloud environment, you can hover over the **Cloud icon** to view the environment labels. ### Action bar Use the action bar to change the data source or source, time-related filters, refresh intervals, and manipulate your data to fit your needs: - The default time range for all panels is 30 mins - If Application Observability shows no data, try and change the time range - Set a time frame to compare metrics - Set the environment to show metrics deployed in that particular environment - Set an attribute to group by your data - Use the dynamic filters to further refine your search - Use the **refresh interval** drop-down to select an automatic refresh interval - Click the **refresh icon** to toggle a manual refresh - On the **Logs** tab, click **Live** to toggle log streaming ### Time frame comparison Use the time frame comparison to compare RED metrics and duration distribution for the current time frame to the previous period or a selection of days, weeks, months, or a year before. ## Service health The three panels in the top row show the [RED method](/blog/2018/08/02/the-red-method-how-to-instrument-your-services#the-red-method) trends for monitoring service health: - **R**ate: the number of requests per second - **E**rrors: the number of errors per second - **D**uration: the 95th percentile request duration And with a time frame comparison the RED metrics panels show the current period with a solid line and the comparison time period with a dotted line. Note the **Duration** metric for time frame comparisons only shows the p95 values. The **Distribution duration** panel shows a histogram for request duration. And with a time frame comparison the distribution duration panel shows the current period in a dark blue and the comparison time period in a light blue. ### Connected services The **Outbound & databases** and **Inbound** panels show a table of connected services and databases. Each row shows the RED metrics trends for request rate, errors, and 95th percentile duration. Click a **service row** to navigate to the service overview page for further details. ### Operations The **Operations** panel shows a table of operations within the service, derived from the `span_name`. Each row shows the RED metrics trends for request rate, errors, and 95th percentile duration. Click an **operation row** to navigate to the **Operation overview** page for detailed RED metrics. #### Operation Overview The **Operation overview** page shows the RED metrics trends for a specific operation. Navigate to the **Traces** tab to search and view traces for the operation. ## Traces Navigate to the **Traces** tab to search and view [traces](/docs/grafana-cloud/send-data/traces/about-traces/) for the service. ### Search Search for traces with the [Trace query language (TraceQL)](/docs/tempo/latest/traceql/). By default, Application Observability filters traces by the service and service namespace. There are two ways to customize search queries: - Click **TraceQL** to use the [Trace query language (TraceQL)](/docs/tempo/latest/traceql/) - Click **Search** to use the visual [TraceQL query builder](/docs/grafana-cloud/send-data/traces/traces-query-editor/traceql-search/) ### View Click a **Trace ID** in the search results to inspect a trace using the trace view. Consult the [trace view](/docs/grafana/latest/explore/trace-integration/#trace-view) documentation to learn how to navigate the trace view and filter spans. ## Logs Navigate to the **Logs** tab to search and view logs for the service. ### Search Search for logs with the [Log Query Language (LogQL)](/docs/loki/latest/logql/). By default, Application Observability filters logs by the service and service namespace. There are two ways to customize search queries: - Click **Code** to use the [Log Query Language (LogQL)](/docs/loki/latest/logql/) - Click **Builder** to use the the visual query builder ### View Application Observability displays log search results in the logs **Volume** and a **Logs** panels. Consult the [Logs visualization documentation](/docs/grafana/latest/explore/logs-integration/#logs-visualization) to learn more. ## Runtime Services that use the OpenTelemetry auto-instrumentation SDKs for .NET, Go, or Java have access to a **Runtime** tab with various CPU and memory utilization graphs. To populate this view, you need the following: - `traces_target_info` - Application Observability generates this label - Your span metrics require the following resource attributes: - `telemetry.sdk.language` - `telemetry.sdk.name` - `telemetry.sdk.version` For for information, see [required metrics and labels documentation](/docs/grafana-cloud/monitor-applications/application-observability/setup/metrics-labels/#span-metrics-and-service-graph-metrics).
