docs: document recent monitoring changes (#17233)
Adds admin and changelog documentation on some recent monitoring changes: - #17072 - #17069 - #17158 - #17070 Dev docs also show up before admin docs if you search for "grafana" or "prometheus", so adds notices that point back to the admin docs.

|
||||
A complete [dashboard reference](dashboards.md) is available for more context on our available service dashboards and panels.
|
||||
|
||||
Additional dashboards can also be set up - see [Grafana configuration](#grafana-configuration) for more details.
|
||||
|
||||
#### View documentation
|
||||
|
||||
On service dashboards, each metric panel has links attached that lead to relevant [alert solutions](alert_solutions.md) or [panel documentation](dashboards.md).
|
||||
These can be accessed from the top left corner of each panel.
|
||||
|
||||
#### View alerts
|
||||
|
||||
The Overview dashboard includes a high-level summary of alert events across all Sourcegraph services.
|
||||
|
||||
On service dashboards, a summary of alert events for that service is available.
|
||||
Alerts can be filtered by level using the "Filter alert level" selector at the top of the dashboard.
|
||||
This information can be overlaid on all panels in that dashboard by enabling the "Alert events" toggle.
|
||||
|
||||
#### View version change events
|
||||
|
||||
On service dashboards, annotations can be displayed for occasions when a Sourcegraph version change is detected by enabling the "Version changes" toggle at the top of the dashboard.
|
||||
This can be useful for correlating metrics and alerts with Sourcegraph deployment and upgrade events.
|
||||
|
||||
#### Querying metrics
|
||||
|
||||
Specific metrics can be queried using Grafana's Explore panel, available at `/-/debug/grafana/explore` on your Sourcegraph instance.
|
||||
The query for each individual panel can be viewed and explored by clicking on the panel and using the "Explore" option.
