promql-validator

You can validate PromQL queries by running them through a Python-based syntax checker that identifies syntactical errors and flags anti-patterns to ensure your Prometheus metrics queries are structurally correct.

Common PromQL anti-patterns include applying rate() to gauge metrics instead of functions like avg_over_time, which degrades performance; identifying these pitfalls helps optimize query speed and reduce Prometheus resource usage.

To optimize slow Prometheus query performance for Grafana dashboards, analyze your metrics queries to identify anti-patterns and apply suggested performance improvements, reducing resource consumption and accelerating dashboard data retrieval.

Yes, you can check Prometheus alerting rules for best practices automatically by using a validation script that analyzes your configurations against detailed guides, identifies performance pitfalls, and suggests optimizations.

Yes, you need Python3 installed in your environment to run this PromQL syntax checker, as it utilizes Python scripts to execute validation logic and enforce best practice checks on your metrics queries.
