This topic explains how Milvus uses Prometheus to monitor metrics and Grafana to visualize metrics and create alerts.
Prometheus is an open-source monitoring and alerting toolkit for Kubernetes implementations. It collects and stores metrics as time-series data. This means that metrics are stored with timestamps when recorded, alongside with optional key-value pairs called labels. Currently Milvus uses the following components of Prometheus:
- Prometheus endpoint to pull data from endpoints set by exporters.
- Prometheus operator to effectively manage Prometheus monitoring instances.
- Kube-prometheus to provide easy to operate end-to-end Kubernetes cluster monitoring.
Grafana is a visualizing stack. It features a dashboard that can help you visualize all the data and metrics you need. With the Grafana dashboard, you can query, understand, and analyze your data.
