- Switch from summary to histogram for vl_http_request_duration_seconds metric. This allows calculating request duration quantiles across multiple hosts via histogram_quantile(0.99, sum(vl_http_request_duration_seconds_bucket) by (vmrange)). - Take into account only successfully processed data ingestion requests when updating vl_http_request_duration_seconds histogram. Failed requests are ignored, since they may significantly skew measurements. - Clarify the description of the change at docs/VictoriaLogs/CHANGELOG.md.
