# tip
* FEATURE: add `/api/v1/status/top_queries` handler, which returns the most frequently executed queries and queries that took the most time for execution. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/907
* FEATURE: vmagent: add support for `proxy_url` config option in Prometheus scrape configs. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/503
* FEATURE: remove parts with stale data as soon as they go outside the configured `-retentionPeriod`. Previously such parts may remain active for long periods of time. This should help reducing disk usage for `-retentionPeriod` smaller than one month.
* FEATURE: vmalert: allow setting multiple values for `-notifier.tlsInsecureSkipVerify` command-line flag per each `-notifier.url`.

Additionally VictoriaMetrics provides the following handlers:
* `/api/v1/series/count` - it returns the total number of time series in the database. Some notes:
* `/api/v1/series/count` - returns the total number of time series in the database. Some notes:
* the handler scans all the inverted index, so it can be slow if the database contains tens of millions of time series;
* the handler may count [deleted time series](#how-to-delete-time-series) additionally to normal time series due to internal implementation restrictions;
* `/api/v1/labels/count` - it returns a list of `label: values_count` entries. It can be used for determining labels with the maximum number of values.
* `/api/v1/status/active_queries` - it returns a list of currently running queries.
* `/api/v1/labels/count` - returns a list of `label: values_count` entries. It can be used for determining labels with the maximum number of values.
* `/api/v1/status/active_queries` - returns a list of currently running queries.
* `/api/v1/status/top_queries` - returns the following query lists:
* the most frequently executed queries - `topByCount`
* queries with the biggest average execution duration - `topByAvgDuration`
* queries that took the most time for execution - `topBySumDuration`
The number of returned queries can be limited via `topN` query arg. Old queries can be filtered out with `maxLifetime` query arg.
For example, request to `/api/v1/status/top_queries?topN=5&maxLifetime=30s` would return up to 5 queries per list, which were executed during the last 30 seconds.
