Checkmate tracks service availability, response times and server health from a self-hosted installation.
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.
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.

Grafana is an open source visualization and dashboarding platform that queries metrics, logs, and traces from Prometheus, Loki, Tempo, and dozens of other backends, with Grafana Cloud offering a hosted option.
Highlight.io was an open-source, full-stack monitoring platform (session replay, errors, logs, traces); its marketing site now redirects to LaunchDarkly, though the GitHub project remains active.
Netdata collects system and service metrics and evaluates alerts near the monitored nodes.
OpenObserve natively unifies logs, metrics, distributed traces, and real-user monitoring in a single self-hostable platform. Written in Rust, it stores data at a fraction of the cost of Elasticsearch.
Prometheus scrapes time-series metrics from instrumented targets, stores them locally, and evaluates alerting rules with PromQL, forwarding alerts to Alertmanager. It has no built-in dashboarding or long-term storage layer of its own.
Sentry provides error tracking, performance monitoring and session replay for web and mobile apps, open source and self-hostable or available as a hosted freemium service.
SigNoz unifies logs, metrics and traces natively on OpenTelemetry, available self-hosted for free or as SigNoz Cloud starting at $49/month.
Uptime Kuma is an open-source, self-hosted monitor for websites, APIs, servers, DNS, SSL certs and Docker containers, with status pages and 90+ notification integrations.
Uptrace unifies OpenTelemetry traces, metrics and logs in one APM tool, free to self-host or run as a usage-based cloud service.
Zabbix monitors servers, network devices, applications and cloud services using agents, SNMP, and other collection methods, with built-in alerting, templates, and high-availability clustering.
