32b9fb58b8 lib/storage: clarify out of retention period error message by mentioning -retentionPeriod command-line flag 2020-07-08 13:54:26 +03:00

12b16077c4 lib/storage: reset MetricName->TSID cache after deleting time series 
This should prevent from adding new data points to deleted time series
without the need to check for the deleted time series.

This improves ingestion performance a bit when the `deleted time series ids` aka `dmis` set
contains big number of time series.

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/596

Based on the idea from @n4mine at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/604

6daa5f7500 lib/storage: prioritize data ingestion over heavy queries 
Heavy queries could result in the lack of CPU resources for processing the current data ingestion stream.
Prevent this by delaying queries' execution until free resources are available for data ingestion.

Expose `vm_search_delays_total` metric, which may be used in for alerting when there is no enough CPU resources
for data ingestion and/or for executing heavy queries.

8b133e40d5 lib/promscrape: prevent from too big deadline misses on scrape retries 
The maximum deadline miss duration is reduced to 2x scrape_interval in the worst case.
By default it is limited to scrape_interval configured for the given scrape target.

2a39ba639d lib/promrelabel: add support for keep_if_equal and drop_if_equal actions to relabel configs 
These actions may be useful for filtering out unneeded targets and/or metrics if they contain equal label values.
For example, the following rule would leave the target only if __meta_kubernetes_annotation_prometheus_io_port
equals __meta_kubernetes_pod_container_port_number:

  - action: keep_if_equal
    source_labels: [__meta_kubernetes_annotation_prometheus_io_port, __meta_kubernetes_pod_container_port_number]

a7797dae09 lib/storage: fix Graphite wildcard matching, which has been broken in v1.36.0 
v1.36.0 always returns empty responses for Graphite wildcards like the following

   {__name__=~"foo\\.[^.]*\\.bar\\.baz"}

Temporary workaround for v1.36.0 is to add `[^.]*` to the end of the regexp.

d186472081 lib/storage: improve search speed for time series matching Graphite whildcards such as foo.*.bar.baz 
Add index for reverse Graphite-like metric names with dots. Use this index during search for filters
like `__name__=~"foo\\.[^.]*\\.bar\\.baz"` which end with non-empty suffix with dots, i.e. `.bar.baz` in this case.

This change may "hide" historical time series during queries. The workaround is to add `[.]*` to the end of regexp label filter,
i.e. "foo\\.[^.]*\\.bar\\.baz" should be substituted with "foo\\.[^.]*\\.bar\\.baz[.]*".
