Infrastructure Monitoring

Infrastructure monitoring in MonSPHERE flows through the real Prometheus ecosystem — the MonSPHERE agent installs and supervises exporters, Prometheus scrapes them, and VictoriaMetrics retains the history.

What's covered

• Server metrics — CPU, memory, disk, and network via node_exporter, installed automatically by the agent.
• Container metrics — Docker container health and resource usage via the agent's Docker Engine API integration.
• Database metrics — connection health and query performance via standard database exporters, configured per host.
• Cloud infrastructure — any cloud VM or managed service that can run the agent or expose a Prometheus endpoint is monitorable the same way; there's no separate "cloud connector" — it's the same exporter pipeline everywhere.

Querying metrics

Every metric collected is a real Prometheus metric, queryable via PromQL through monitoring-api, and the same data backs dashboards and reports — there's no separate "infrastructure" data silo from "website monitoring" data.

Retention

Metric time series live in VictoriaMetrics, which keeps them beyond Prometheus's own short local window — currently one month on every plan — so dashboards and reports can look back that far. Your plan's history retention (see Licensing & Subscriptions) applies to per-check history, not to these metrics.
