Then we add the EPEL repository, as follows:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\"># yum install epel-release<\/pre>\n\n\n\n<p>As we have updated the EPEL repository on the server, Now we can install the mytop package using the EPEL repository with the below command.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\"># yum install mytop \u2013y<\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Configuring the Mytop Package on CentOS 7<\/h3>\n\n\n\n<p>We have to configure the mytop using the customized file .mytop to create the configuration file, run the below command, add the configuration given below:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\"># vi ~\/.mytop\n\nhost=localhost\ndb=mysql\ndelay=3\nport=3306\nsocket=\nbatchmode=0\ncolor=1\nidle=2<\/pre>\n\n\n\n<p>Once done, you can check the MySQL processes real time using below command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\"># mytop<\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Shortcut Keys for mytop Command<\/h3>\n\n\n\n<p>The following keys performs various actions while mytop is running:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">? Display help.\nc Show \"command counters\" based on the Com_* values in SHOW GLOBAL STATUS. This is a new feature.\nFeedback welcome.\nd Show only threads connected to a particular database.\nf Given a thread id, display the entire query that thread was (and still may be) running.\nF Disable all filtering (host, user, and db).\nh Only show queries from a particular host.\nH Toggle the header display. You can also specify either \"header=0\" or \"header=1\" in your config file to\nset the default behavior.\ni Toggle the display of idle (sleeping) threads. If sleeping threads are filtered, the default sorting\norder is reversed so that the longest running queries appear at the top of the list.\nI Switch to InnoDB Status mode. The output of \"SHOW INNODB STATUS\" will be displayed every cycle. In a\nfuture version, this may actually summarize that data rather than producing raw output.\nk Kill a thread.\nm Toggle modes. Currently this switches from `top' mode to `qps' (Queries Per Second Mode). In this mode,\nmytop will write out one integer per second. The number written reflects the number of queries executed\nby the server in the previous one second interval.\nMore modes may be added in the future.\no Reverse the default sort order.\np Pause display.\nq Quit mytop\nr Reset the server's status counters via a FLUSH STATUS command.\ns Change the sleep time (number of seconds between display refreshes).\nu Show only threads owned by a giver user.<\/pre>\n","protected":false},"excerpt":{"rendered":"<p>Mytop is an open source, command line tool used for monitoring MySQL performance.
