slo-tracker

Minimal CLI for tracking SLO burn rates from Prometheus. Outputs a quick summary to stdout — useful for morning standups and incident reviews.

Built for my own use. Tested on the Nexus prod setup.

Usage

python slo_tracker.py --config slos.yml --window 7d

Config format

slos:
  - name: "API availability"
    query: 'sum(rate(http_requests_total{code!~"5.."}[5m])) / sum(rate(http_requests_total[5m]))'
    target: 0.999
    window: 30d

Requirements

pip install prometheus-api-client pyyaml rich
