Get started with Grafana Tempo
You can use Grafana Cloud to avoid installing, maintaining, and scaling your own instance of Grafana Tempo. Create a free account to get started, which includes free forever access to 10k metrics, 50GB logs, 50GB traces, & more.
Distributed tracing visualizes the lifecycle of a request as it passes through a set of applications. For more information about traces, refer to What are traces?.
Grafana Tempo is an open-source, easy-to-use, and high-scale distributed tracing backend. Tempo lets you search for traces, generate metrics from spans, and link your tracing data with logs and metrics.
To build a tracing pipeline, you need four major components: client instrumentation, pipeline, backend, and visualization.
This diagram illustrates a tracing system configuration:
Client instrumentation (1 in the diagram) is the first building block to a functioning distributed tracing visualization pipeline. Client instrumentation is the process of adding instrumentation points in the application that create and offload spans.
Most of the popular client instrumentation frameworks have SDKs in the most commonly used programming languages. You should pick one according to your application needs.
Some languages have support for auto-instrumentation. These libraries capture telemetry information from a client application with minimal manual instrumentation of the codebase.
- OpenTelemetry Java auto-instrumentation
- OpenTelemetry .NET auto-instrumentation
- OpenTelemetry Python auto-instrumentation
Note: Check out the instrumentation references to learn how to instrument your favorite language for distributed tracing.
Pipeline (Grafana Agent)
Once your application is instrumented for tracing, the traces need to be sent to a backend for storage and visualization. You can build a tracing pipeline that offloads spans from your application, buffers them, and eventually forwards them to a backend. Tracing pipelines are optional (most clients can send directly to Tempo), but the pipelines become more critical the larger and more robust your tracing system is.
The Grafana Agent is a service that is deployed close to the application, either on the same node or within the same cluster (in Kubernetes) to quickly offload traces from the application and forward them to a storage backend. The Grafana Agent also abstracts features like trace batching to a remote trace backend store, including retries on write failures.
To learn more about the Grafana Agent and how to set it up for tracing with Tempo, refer to this blog post.
Grafana Tempo is an easy-to-use and high-scale distributed tracing backend used to store and query traces. The tracing backend stores and retrieves traces on demand.
