Performance drop for exposing application metrics in Prometheus format is close to zero. These metrics are usually some counters, which are updated atomically in a few nanoseconds. Prometheus scrapes these metrics once per 10-30 seconds, so generating the /metrics response in Prometheus text exposition format doesn't need a lot of CPU, especially if using a library optimized for simplicity and speed like https://github.com/VictoriaMetrics/metrics/ |
