Logging and monitoring

Learn how to use built-in monitoring and logging for on-prem PerfectScale installation

PerfectScale provides built-in monitoring and logging capabilities for your on-premises installation.

To collect key system metrics and enable effective monitoring, the installation includes Prometheus, Grafana, and necessary exporters. For logging, Loki works alongside Promtail agents to efficiently collect and manage log data.

Remote logging and the ability to write to PerfectScale's centralized Prometheus and Loki instances remotely are enabled by default; however, this feature is optional. Port forwarding provides access to Prometheus and Grafana for viewing logs and metrics.
