MySQL Monitoring using Prometheus & Grafana
Download as pptx, pdf11 likes4,496 views
This document describes how to set up monitoring for MySQL databases using Prometheus and Grafana. It includes instructions for installing and configuring Prometheus and Alertmanager on a monitoring server to scrape metrics from node_exporter and mysql_exporter. Ansible playbooks are provided to automatically install the exporters and configure Prometheus. Finally, steps are outlined for creating Grafana dashboards to visualize the metrics and monitor MySQL performance.
