![]() Step 4 – Configure Monit To Monitor MySQL/MariaDB Now restart monit service using service monit restart and check the status of service using command line. Stop program = "/etc/init.d/apache2 stop" Start program = "/etc/init.d/apache2 start" with timeout 60 seconds Start program = "/etc/init.d/httpd start" with timeout 60 secondsĬheck process apache with pidfile /run/apache2.pid ![]() Edit your monit configuration file and add following settings at end of file On CentOS, RHEL: /etc/nfĬheck process apache with pidfile /var/run/httpd.pid The very first service we are adding Apache. Let’s start with adding services in Monit to monitor them and take necessary action on condition meet. ![]() Step 3 – Monitor Apache Service with Monit Now access Monit web interface by pointing your browser to 2812 on localhost To change default port simply update first line of above showing configuration and set your preferred port. Starting monit: monit: generated unique Monit id 0dbd9dc3f0aa7ed7df9e7a069aea9b84 and stored to '/root/.monit.id' Īs per above configuration monit will start on port 2812 and only accessible from localhost. To enable monit web interface, edit configuration file ( For RHEL based /etc/nf & For Dabian Based System /etc/monit/monitrc ) in your favorite editor and uncomment following lines (Optional For CLI Lovers) Monit also provided an web interface to view services and processes status. For CentOS/RHEL users need to enable epel repository in his system before installing it. Monit can be easily installed with package manager in most of Linux flavors. In this article we will only show you configuration for few services only. Monit has capability to monitory any of services running on system, We just only need to add settings in it. This article will help you to install and configure Monit on CentOS, RHEL, Fedora, Ubuntu, Dabian and Scientific Linux. Monit monitors the server programs to increase services uptime and ensures that they stay online consistently. do not ignore slow queries: enable slow query log and use mysqldumpslow script (it's included in MySQL distribution) on a regular basis.Monit, A Process and Services Monitoring Tool is a small Open Source utility for monitoring and managing Unix like systems.SQL process sampling ( show full processlist) when you notice your database performance is congested.You also should not ignore traditional approaches: This statistics can give you a brief overview on how your databases are utulized by different users. Either products include user statistics: in MariaDB and in Percona Server. Nevertheless some solutions do exist: both MariaDB and Percona Server can be used as a drop-in replacement for traditional MySQL. As all your sites are served from one MySQL instance (if I understand you right), you cannot rely on per-process/user statistics as described above. On the bright side, this won't need any changes to your system except for the package setup and enabling accounting. However, this method would only account for finished processes. If using cgroups is not the case, you can also install psacct package and use sa -m command (enable accounting beforehand with accton). You might need to adjust your setup though, ensuring your processes are bound to relevant control groups (as your sites are running under different system accounts, this should not be hard to implement). They'll give you fine-grained statistics on resource usage. Utilize cgroups, cpuacct and memory controllers in particular.
