You can monitor using prometheus or grafana.
Prometheus collects metrics from monitored targets by scraping metrics HTTP endpoints on these targets. Since Prometheus also exposes data in the same manner about itself, it can also scrape and monitor its own health.
Grafana allows you to query, visualize, alert on and understand your metrics no matter where they are stored.
You can create a dashboard or import or new dashboard folder. Dashboards can be managed, and can create new playlists. You can add notification channels or alert rules. You can also manage all users and organizations.
