I am trying to evaluate performance of filebeat instalation in a K8S, for that I was able to export filebeat metrics to prometheus.
I was unable to find any comprehensive documentation regarding the metrics, so I am not sure which one are counters or gauges, nor I know the real meaning of all metrics. I checked this documentation, but there are missing metrics and it seems that some metrics have troubleshoot hints that are wrong. There is no information on which is counter or gauge.
Is there anywhere that will have explanation for each metric and metric type as well (counter or gauge)?
Thanks in advance
