VictoriaMetrics is a fast, cost-effective and scalable monitoring solution and time series database.

It is designed to collect, store, and process real-time metrics, making it an excellent choice for monitoring applications, infrastructure, and business metrics. VictoriaMetrics can be used as a long-term remote storage for Prometheus or as a drop-in replacement for Prometheus with better performance and lower resource usage.

Key features: - High performance and resource efficiency - Excellent compression for time series data - Easy to operate and maintain - Horizontal scalability - Global query view - Long-term storage - Prometheus compatibility

Storage Configuration:

The example deployment uses emptyDir storage for universal compatibility. Data will be lost on pod restart.

For production use, configure persistent storage:

victoriametrics:
  victoria-metrics-single:
    server:
      persistentVolume:
        enabled: true
        size: 100Gi
        storageClass: "your-storage-class"

For additional configuration options including authentication, retention settings, and performance tuning, refer to the official VictoriaMetrics Helm chart documentation.

Storage Requirements:

• Testing/Evaluation: Uses emptyDir storage (data lost on restart) - works on any cluster
• Production: Requires persistent volumes with a configured StorageClass

Network Access:

• LoadBalancer service type is used for external access
• Port 8428 for VictoriaMetrics HTTP API and web interface
