About OpenTelemetry metrics

The OpenTelemetry monitoring stack is based on industry-standard observability tools and includes various components for collecting, processing, and storing metrics. This comprehensive approach provides a complete view of your system's performance and health across all components of your {% data variables.product.prodname_ghe_server %} instance.

Benefits of OpenTelemetry metrics

OpenTelemetry metrics offer several advantages over the legacy collectd system:

• Industry standard: Based on widely adopted OpenTelemetry and Prometheus standards
• Scalable storage: VictoriaMetrics provides efficient time-series data storage
• Rich visualization: Grafana offers advanced dashboard and alerting capabilities
• Extensible: Support for custom metrics and external monitoring integrations
• Native endpoints: Direct integration with service /metrics endpoints for efficient monitoring

With OpenTelemetry, advanced Grafana dashboards with enhanced visualization and monitoring capabilities are available, see: AUTOTITLE.

Key components

The OpenTelemetry monitoring stack includes the following components:

• OpenTelemetry Collector: Receives, processes, and exports telemetry data, acting as the central hub for collecting metrics from various sources
• VictoriaMetrics: A fast, efficient, and scalable time-series database that stores all metrics collected from your {% data variables.product.prodname_ghe_server %} instance
• Grafana: Provides powerful visualization capabilities for time-series data, allowing you to create, explore, and share dashboards
• Exporters: Specialized components that collect metrics from specific services, including:
  • Node exporter: System-level metrics including CPU, memory, disk, and network statistics
  • Process exporter: Detailed process-level metrics and resource utilization
  • StatsD exporter: Used by {% data variables.product.github %} components to expose application-level metrics using the StatsD protocol
  • HAProxy exporter: Load balancer metrics for frontend, cluster, and data tiers
  • Nomad exporter: Job scheduler and resource allocation metrics (native Nomad /v1/metrics endpoint)
  • MySQL exporter: Database performance and query metrics (when MySQL is enabled)
  • Elasticsearch exporter: Search engine performance and indexing metrics (when Elasticsearch is enabled)
  • Redis exporter: Cache performance and memory usage metrics (when Redis is enabled)
  • Memcached exporter: Cache hit rates and memory statistics (when Memcached is enabled)
  • MinIO exporter: Object storage cluster metrics (native MinIO /minio/v2/metrics/cluster endpoint, when MinIO is enabled)
  • Nginx exporter: Web server performance and request metrics (when Nginx is enabled)
  • SQL exporter: Microsoft SQL Server metrics (when SQL Server is enabled)
  • Blackbox exporter: Network probe and connectivity metrics (in cluster deployments)
• Custom metrics services: Additional {% data variables.product.github %}-specific services that push OpenTelemetry metrics directly to the collector, including:
  • Resque metrics: Background job processing and queue metrics
  • Postfix metrics: Email delivery and mail server performance metrics
  • Listener stats metrics: Connection and request handling statistics
  • WireGuard metrics: VPN tunnel and network encryption metrics
