Awesome Nomad › Monitoring and Logging
mr-karan/nomad-monitoring
The project "nomad-monitoring" is a comprehensive collection of jobspecs and Grafana dashboards designed specifically for end-to-end monitoring of HashiCorp Nomad clusters. It provides a robust solution to monitor the health, resource usage, and performance metrics of Nomad servers, clients, and allocations. The dashboards included in the project allow users to visualize critical metrics such as CPU, memory, disk usage, Raft usage, and RPC usage, offering a detailed insight into the operational status of Nomad clusters. The project leverages Nomad's built-in metrics publication capabilities, which simplifies the collection of monitoring data without the need for third-party tools. It uses Prometheus metrics enabled through Nomad's telemetry configuration, allowing for efficient and standardized metrics collection. The repository demonstrates the use of "vmagent," a lightweight metrics collection agent from VictoriaMetrics, chosen for its user-friendly configuration and low resource consumption. This agent collects Prometheus metrics and forwards them to VictoriaMetrics, a time-series database optimized for handling large volumes of active time series data with efficient storage and configurable retention periods. The project also addresses service discovery challenges within Nomad namespaces, highlighting current limitations and suggesting solutions such as using Consul for service discovery or deploying vmagent instances per namespace. It provides practical instructions for running a local Nomad agent and deploying the full monitoring stack, including Grafana, VictoriaMetrics, and vmagent. Overall, "nomad-monitoring" is a valuable toolset for administrators and operators of Nomad clusters who need detailed, real-time monitoring and visualization of their infrastructure's performance and health. It integrates seamlessly with existing Nomad telemetry features and enhances observability through well-designed dashboards and efficient metrics collection and storage mechanisms.
