Monitor Promscale

Promscale includes a set of out-of-the-box alerts, runbooks, and a Grafana dashboard that you can use to monitor it.

note

To monitor Promscale, make sure that a Prometheus instance is scraping the Promscale HTTP metrics endpoint, which defaults to port 9201 port in the /metrics API. Use Prometheus to evaluate the Promscale alerting rules, and configure Prometheus as a data source in Grafana to visualize the Promscale dashboard. This helps to troubleshoot issues when Promscale isn't working as expected. You should be using a separate Prometheus instance and not Promscale. You don't want your monitoring tool monitoring itself.

Dashboard

The Grafana dashboard consists of Promscale metrics grouped in several rows:

  • Overview
  • Ingest
  • Query
  • Database
  • Cache

Alerts

You can configure alerting rules for Promscale to send alerts when something doesn't work as expected in Promscale.

Here are the alerting rules for Promscale. These alerting rules should be configured on the Prometheus instance that you are using to monitor Promscale.

Runbooks

When an alert is sent, the alert message references the relevant runbook to troubleshoot and mitigate the issue. These runbooks are published and maintained in the Promscale Github repository.
