Whittling down the MySQL process list

Project description

Maintainer: k dot shenk at gmail dot com

The aim of mypsl is to provide a simple interface for querying and filtering the MySQL process list. Over time the available options have become bloated, so some cases may not be so simple.

Installation

Via PIP: pip install mypsl

Usage

usage: mypsl [-h] [-H HOST] [-p PORT] [-u USER] [-P PASSWD] [-ch CHARSET]
     [--config CONNECT_CONFIG] [-sm SALT_MINION]
     [-l LOOP_SECOND_INTERVAL] [-lm LOOP_MAX] [-dft] [-c COMMAND]
     [-s STATE] [-t TIME] [-d DATABASE] [-q QUERY] [-i] [-isr]
     [--debug] [-o ORDER_BY] [-T] [-v] [--slack] [--kill]
     [-kt KILL_THRESHOLD] [-ka] [-ky] [-kl KILL_LOG] [-klo]

(mypsl: mypsl: 0.19) :: MySQL Process list watcher & query
killer.

optional arguments:
  -h, --help            show this help message and exit

Connection Options:
  -H HOST, --host HOST  The host to get the process list from. If localhost,
                        we will attempt to find and use the socket file first.
                        (default: localhost)
  -p PORT, --port PORT  The host's port. If the host is localhost, we will
                        attempt to find and use the socket file first.
                        (default: 3306)
  -u USER, --user USER  The user to connect to the host as. (default: root)

  -sm SALT_MINION, --salt-minion SALT_MINION
                        Connect to mysql running on a salt minion. Do not use
                        any other connection options with this.

  -l LOOP_SECOND_INTERVAL, --loop LOOP_SECOND_INTERVAL
                        Time in seconds between getting the process list.

Kill Options:
  --kill                Kill the queries that we find. (default: False)
  -kt KILL_THRESHOLD, --kill_threshold KILL_THRESHOLD
                        The kill threshold. If a number is provided, we'll
                        need to hit that many total connections before killing
                        queries. You can set this to 'off' as well, which
                        kills queries no matter how many connections there
                        are. (default: 100)
  -ka, --kill_all       If this flag is provided, we'll attempt to kill
                        everything, not only select queries. Use with
                        caution! (default: False)
  -ky, --kill_yes       If this is provided we won't stop to ask if you are
                        sure that you want to kill queries. (default: False)
  -kl KILL_LOG, --kill_log KILL_LOG
                        Where to log killed queries to, granting permissions
                        to write to this file. (default:
                        /var/log/killed_queries.log)
  -klo, --kill_log_only
                        Only log the queries that would be killed, do not
                        actually kill them (default: False)
