 This section provides guidelines and example queries using Redpanda's public metrics to optimize your system's performance and monitor its health.
 
-TIP: To help detect and mitigate anomalous system behaviors, capture baseline metrics of your healthy system at different stages (at start-up, under high load, in steady state) so you can set thresholds and alerts according to those baselines.

+====
+For counter type metrics, a broker restart causes the count in tools such as Prometheus and Grafana to reset to zero. Redpanda recommends wrapping counter metrics in a rate query to account for broker restarts, for example:

+[,promql]

+rate(redpanda_kafka_records_produced_total[5m])

-Before v22.2, a Redpanda broker provided metrics only through the xref:reference:internal-metrics-reference.adoc[`/metrics`] endpoint through the Admin API port. While Redpanda still provides this endpoint, it includes many internal metrics that are unnecessary for a typical Redpanda user to monitor. Consequently, the `/public_metrics` endpoint was added to provide a smaller set of important metrics that can be queried and ingested more quickly and inexpensively. The `/metrics` endpoint is now referred to as the 'internal metrics' endpoint, and Redpanda recommends that you use it for development, testing, and analysis.
