Core Functions of PromQL Advisor
Query Construction
Examplerate(http_requests_total[5m])
ScenarioA user managing a web service wants to know the rate of HTTP requests in the last 5 minutes to monitor traffic spikes or drops. The Advisor provides the correct syntax and explains how the 'rate' function calculates the per-second average rate of increase.
Optimization Tips
Examplesum by (job) (increase(process_cpu_seconds_total[1h]))
ScenarioAn IT operations manager needs to aggregate CPU usage by job over the last hour to allocate resources efficiently. The Advisor suggests using 'sum by (job)' for aggregation and 'increase' to measure total increments, offering advice on optimizing the query for better performance.
Troubleshooting Queries
Examplehistogram_quantile(0.95, sum(rate(http_request_duration_seconds_bucket[10m])) by (le))
ScenarioA performance analyst is trying to calculate the 95th percentile of request durations to identify outliers. The Advisor checks the query for common mistakes like incorrect label matching or misuse of the 'histogram_quantile' function, ensuring accurate results.
