I think it would be great if Go runtime could maintain a separate epoll file descriptor (epfd) per each P. Then every P could register file descriptors in its own...

@aluode99 , the purpose of `-search.maxSamplesPerQuery` is to limit CPU usage per single query - see https://docs.victoriametrics.com/#resource-usage-limits . VictoriaMetrics spends CPU time on unpacking all the samples for all the...

Closing the issue as "working as intended".

If the `-promscrape.noStaleMarkers` command-line flag resolves the issue, then it is likely the issue is related to [staleness handling](https://docs.victoriametrics.com/vmagent.html#prometheus-staleness-markers). Probably the `NetApp Harvest` exporter periodically stops exporting some metrics, which...

@hagen1778 , how about adding `sort_labels` option at [scrape_config](https://docs.victoriametrics.com/sd_configs.html#scrape_configs) level? If it is set to true, then sort labels in scraped metrics before checking for [stale metrics](https://docs.victoriametrics.com/vmagent.html#prometheus-staleness-markers). By default the...

The temporary workaround is to disable [staleness markers](https://docs.victoriametrics.com/vmagent.html#prometheus-staleness-markers) for scrape targets, which change the order of labels for the same metrics between scrapes. This can be done in the following...

Did you set `-search.maxStalenessInterval` or `-search.maxLookback` command-line options when running VictoriaMetrics? Or probably you set up `max_lookback` query arg for the Grafana datasource used for querying VictoriaMetrics? These options limit...

> I tried `last_over_time(info[d])` for various d, and it did not help. Do not set `[d]` - just use `last_over_time(info)` - in this case VictoriaMetrics must automatically set the lookbehind...

FYI, it is possible to specify passwords in `-auth.config` via environment variables. For example, the following config automatically replaces `%{PASSWORD_FROM_ENV_VAR}` with the value of `PASSWORD_FROM_ENV_VAR` environment variable: ```yaml users: -...

@jiangxinlingdu , could you upgrade to the [latest available release of vmagent](https://docs.victoriametrics.com/CHANGELOG.html) and verify whether the issue is fixed there?
