Technical shortlist
Open-source monitoring tools for production systems
Start with the signals and retention you need. Metrics, logs, traces, profiles and uptime checks create different storage, query and alerting requirements; no single open-source stack is automatically the simplest option.
For SREs, platform engineers, DevOps teams and sysadmins operating applications, Kubernetes clusters, servers and network services.
Lead with the workload
The decision to make
Choose the smallest architecture that meets your incident workflow. Validate ingestion volume, cardinality, retention, query latency, alert routing, access control and upgrade behavior before production rollout.
