Fractal Techware — SRE Toolkit

Alerts that fire,
runbooks that answer.

Six packs for the people who carry the pager. Every alert ships with promtool unit tests and a runbook. Every config is validated against the real binary. Nothing here ships until its own suite has run.

The four-pack

SRE Observability Bundle

Four packs built to work together: the Collector recipes feed Prometheus, the alerts fire on exactly the labels the dashboards chart, and the hardening policies pass against all of them.

  • OpenTelemetry Collector Production Recipes (Pro)
  • Prometheus Alert Rules & Runbook Pack (Pro)
  • Grafana Observability Dashboard Pack (Pro)
  • Kubernetes Hardening Baseline Kit (Pro)
