Overview

Grafana

The open-source platform for monitoring and observability.

License Circle CI Go Report Card

Grafana allows you to query, visualize, alert on and understand your metrics no matter where they are stored. Create, explore, and share dashboards with your team and foster a data driven culture:

  • Visualize: Fast and flexible client side graphs with a multitude of options. Panel plugins offer many different ways to visualize metrics and logs.
  • Dynamic Dashboards: Create dynamic & reusable dashboards with template variables that appear as dropdowns at the top of the dashboard.
  • Explore Metrics: Explore your data through ad-hoc queries and dynamic drilldown. Split view and compare different time ranges, queries and data sources side by side.
  • Explore Logs: Experience the magic of switching from metrics to logs with preserved label filters. Quickly search through all your logs or streaming them live.
  • Alerting: Visually define alert rules for your most important metrics. Grafana will continuously evaluate and send notifications to systems like Slack, PagerDuty, VictorOps, OpsGenie.
  • Mixed Data Sources: Mix different data sources in the same graph! You can specify a data source on a per-query basis. This works for even custom datasources.

  • Test Datasource: do not use global random

    Test Datasource: do not use global random

    What is this feature? In alerting we do some performance testing using the test data source with function RandomWalk. During investigating performance problems I found that the RandomWalk method was the bottleneck. This happens because it uses global randomizer instance, that has synchronous access guarded by a mutex.

    This PR updates test data source to not use the global randomizer.

  • Traces: Create span when a new session is opened

    Traces: Create span when a new session is opened

    What is this feature? When I tested changes in https://github.com/grafana/grafana/pull/61109 I found serious difference between top-level spans and query execution spans (sometimes seconds). It turned out that in my tests the code was blocked on starting a new session.

    This PR adds a tracing span that records when the session is open and closed. This will make db operations more visible because real duration of the query does not indicate the time it took to get data from database.

    image

    for example, this trace is much useful because it shows that although query took 3.78ms, the real db access took more than 4.8s ! Also, it revealed some unnecessary session opening, which is fixed in https://github.com/grafana/grafana/pull/61117

  • Alerting: Add client configuration for remote Loki historian backend and test connection

    Alerting: Add client configuration for remote Loki historian backend and test connection

    What is this feature?

    This PR creates and allows configuration of a Loki client, to be used in the remote loki state historian backend. We configure the client with a URL only (for now), and verify that we are able to communicate with Loki on startup.

    As in the previous PR, the configuration options are intentionally not documented. We might break them in the future.

    Which issue(s) does this PR fix?:

  • Traces: Fix timestamp for database query traces

    Traces: Fix timestamp for database query traces

    What is this feature? Grafana support tracing of database queries. However, the trace span starts when the query is already executed and closed almost immediately.

    https://github.com/grafana/grafana/blob/862a6a2fa625100b690c5a48a9b12e7a7dd42041/pkg/services/sqlstore/database_wrapper.go#L98-L108

    This makes span duration to be wrong:

    This PR updates the creation of the span and provides the actual query start timestamp

    Note: this fixes only OpenTelemetry mode. OpenTracing implementation does ignores the options
