--- title: InfluxQL query management description: Show, kill, and manage queries in InfluxQL. url: https://docs.influxdata.com/influxdb/v1/troubleshooting/query_management/ estimated_tokens: 2481 product: InfluxDB OSS v1 version: v1 --- # InfluxQL query management This page documents an earlier version of InfluxDB OSS. [InfluxDB 3 Core](/influxdb3/core/) is the latest stable version. Manage your InfluxQL queries using the following: - [SHOW QUERIES](#list-currently-running-queries-with-show-queries) to identify currently-running queries - [KILL QUERIES](#stop-currently-running-queries-with-kill-query) to stop queries overloading your system - [Configuration settings](#configuration-settings-for-query-management) to prevent and halt the execution of inefficient queries > The commands and configurations provided on this page are for **Influx Query Language (InfluxQL) only** – **no equivalent set of Flux commands and configurations currently exists**. For the most current Flux documentation, see [Get started with Flux](/influxdb/v1/flux/get-started/). ## List currently-running queries with `SHOW QUERIES` `SHOW QUERIES` lists the query id, query text, relevant database, duration, status, and user of all currently-running queries on your InfluxDB instance. #### Syntax ```sql SHOW QUERIES ``` #### Example ``` > SHOW QUERIES qid query database duration status user --- ----- -------- -------- ------ ---- 37 SHOW QUERIES 100368u running admin 36 SELECT mean(myfield) FROM mymeas mydb 3s running jdoe ``` ##### Explanation of the output - `qid`: The id number of the query. Use this value with [`KILL - QUERY`](/influxdb/v1/troubleshooting/query_management/#stop-currently-running-queries-with-kill-query). - `query`: The query text. - `database`: The database targeted by the query. - `duration`: The length of time that the query has been running. See [Query Language Reference](/influxdb/v1/query_language/spec/#durations) for an explanation of time units in InfluxDB databases. `SHOW QUERIES` may output a killed query and continue to increment its duration until the query record is cleared from memory. - `status`: The current status of the query. - `user`: The user who initiated the query. Empty if authentication is not enabled. *v1.12.3+* ## Stop currently-running queries with `KILL QUERY` `KILL QUERY` tells InfluxDB to stop running the relevant query. #### Syntax Where `qid` is the query ID, displayed in the [`SHOW QUERIES`](/influxdb/v1/troubleshooting/query_management/#list-currently-running-queries-with-show-queries) output: ```sql KILL QUERY ``` ***InfluxDB Enterprise clusters:*** To kill queries on a cluster, you need to specify the query ID (qid) and the TCP host (for example, `myhost:8088`), available in the `SHOW QUERIES` output. ```sql KILL QUERY ON "" ``` A successful `KILL QUERY` query returns no results. #### Examples ```sql -- kill query with qid of 36 on the local host > KILL QUERY 36 > ``` ```sql -- kill query on InfluxDB Enterprise cluster > KILL QUERY 53 ON "myhost:8088" > ``` ## Configuration settings for query management The following configuration settings are in the [coordinator](/influxdb/v1/administration/config/#query-management-settings) section of the configuration file. ### `max-concurrent-queries` The maximum number of running queries allowed on your instance. The default setting (`0`) allows for an unlimited number of queries. If you exceed `max-concurrent-queries`, InfluxDB does not execute the query and outputs the following error: ``` ERR: max concurrent queries reached ``` ### `query-timeout` The maximum time for which a query can run on your instance before InfluxDB kills the query. The default setting (`"0"`) allows queries to run with no time restrictions. This setting is a [duration literal](/influxdb/v1/query_language/spec/#durations). If your query exceeds the query timeout, InfluxDB kills the query and outputs the following error: ``` ERR: query timeout reached ``` ### `log-queries-after` The maximum time a query can run after which InfluxDB logs the query with a `Detected slow query` message. The default setting (`"0"`) will never tell InfluxDB to log the query. This setting is a [duration literal](/influxdb/v1/query_language/spec/#durations). Example log output with `log-queries-after` set to `"1s"`: ``` [query] 2016/04/28 14:11:31 Detected slow query: SELECT mean(usage_idle) FROM cpu WHERE time >= 0 GROUP BY time(20s) (qid: 3, database: telegraf, threshold: 1s) ``` `qid` is the id number of the query. Use this value with [`KILL QUERY`](/influxdb/v1/troubleshooting/query_management/#stop-currently-running-queries-with-kill-query). The default location for the log output file is `/var/log/influxdb/influxdb.log`. However on systems that use systemd (most modern Linux distributions) those logs are output to `journalctl`. You should be able to view the InfluxDB logs using the following command: `journalctl -u influxdb` ### `max-select-point` The maximum number of [points](/influxdb/v1/concepts/glossary/#point) that a `SELECT` statement can process. The default setting (`0`) allows the `SELECT` statement to process an unlimited number of points. If your query exceeds `max-select-point`, InfluxDB kills the query and outputs the following error: ``` ERR: max number of points reached ``` InfluxDB checks the point count every second (so queries exceeding the maximum aren’t immediately aborted). ### `max-select-series` The maximum number of [series](/influxdb/v1/concepts/glossary/#series) that a `SELECT` statement can process. The default setting (`0`) allows the `SELECT` statement to process an unlimited number of series. If your query exceeds `max-select-series`, InfluxDB does not execute the query and outputs the following error: ``` ERR: max select series count exceeded: series ``` ### `max-select-buckets` The maximum number of `GROUP BY time()` buckets that a query can process. The default setting (`0`) allows a query to process an unlimited number of buckets. If your query exceeds `max-select-buckets`, InfluxDB does not execute the query and outputs the following error: ``` ERR: max select bucket count exceeded: buckets ```
