Categraf is an all-in-one telemetry collector written in Go that gathers metrics and logs from physical machines, VMs, switches, containers, Kubernetes, middleware, and databases. It pushes data via the remote write protocol to backends like Nightingale, Prometheus, and VictoriaMetrics, and ships with nearly a hundred built-in collection plugins plus bundled dashboards and alert rules.

Use cases

• collect server metrics and logs with a single agent
• monitor kubernetes containers and nodes
• push telemetry to nightingale or victoriaMetrics via remote write
• replace multiple exporters with one monitoring agent
• collect metrics from databases and middleware like mysql and redis
• deploy a monitoring agent as a kubernetes daemonset
• monitor hybrid cloud and multi-cloud infrastructure

When to choose

• you use Nightingale (or Prometheus/VictoriaMetrics) and want a single agent for metrics and logs
• you want out-of-the-box dashboards and alert rules for common OS, middleware, and database targets
• you need push-based collection to minimize inbound network exposure
• you want Telegraf-style plugins with high-cardinality safeguards built in

When to avoid

• you need OpenTelemetry-native tracing/APM collection rather than metrics and logs
• you already run a mature Telegraf, Prometheus node_exporter, or OTel Collector pipeline you don't want to migrate
• you need a pull-based scraping model instead of push remote write
