Updated Prometheus metrics (#11141) * Add metrics for nodes online and offline * Add cluster capacity metrics * Introduce v2 metrics
2021-01-18 23:35:38 -05:00
# List of metrics reported cluster wide
add support for bucket level request count per API (#17468) New metrics added to calculate API request count per bucket, per API. Captures errors, including 4xx, 5xx HTTP status codes separately.
2023-06-21 12:41:59 -04:00
Each metric includes a label for the server that calculated the metric. Each metric has a label for the server that generated the metric.
