![]() MySQL is used only to store your Grafana settings and does not store any time series data. The Healthwatch tile then exports the collected metrics to dashboards in the Grafana UI, allowing you to visualize the data with charts and graphs and create customized dashboards for long-term monitoring and troubleshooting. The Prometheus instance scrapes and stores metrics from the Healthwatch Exporter tiles, allows you to configure alerts with Alertmanager, and sends canary tests to target URLs with Blackbox Exporter. ![]() The main three components of the Healthwatch tile are Prometheus, Grafana, and MySQL. The problem is only with percona1 and to me it looks like it is systemd related.This topic describes Healthwatch for VMware Tanzu tile components and the resource requirements for the Healthwatch tile.įor information about the metric exporter VMs that the Healthwatch Exporter for VMware Tanzu Application Service for VMs (TAS for VMs) and Healthwatch Exporter for Tanzu Kubernetes Grid Integrated Edition (TKGI) tiles deploy, see Healthwatch Metrics.
