If you are running a heartbeat/pacemaker cluster with built-in monitoring, you will not want your monitoring agents to restart the services. Whether or not you decide to implement corrective action on events will depend upon your systems architecture.

License is a one-time payment (non-reccuring cost) and does not expire.

The MMonit package is proprietary software, with support licenses of Basic (eu: 129 - 10 clients), Professional (eu: 229 - unlimited clients), Premium (eu: 998 - unlimited clients - source access). The MMonit package extends the basic (free) monit program by adding a central monitoring service, with historical tracking of events. Monit provides a web interface that can be used to not just query monitor status but to also control the monitoring of configured services. You also noticed that the monitoring program will take corrective action either in the form of restarting the service, or generating an alert. This says that we generate an alert if the load average is greater than 4 for 5 polling cycles.Īs you can see, the configuration file is easy to interpret, human readable. If loadavg (1min) > 4 for 5 cycles then alert

This says to timeout the service if it had to be restarted 2 times within 3 polling intervals. One of the features I liked was the ability to use 'conditional logic' in determining the alert action. If failed checksum then exec '/watch/dog' # Run /watch/dog in the case that the binary was changed Then exec '/usr/local/apache/bin/apachectl graceful' # Reload apache if the nf file was changed If failed port 80 protocol http then restart If cpu usage > 95% for 3 cycles then restart If 2 restarts within 3 cycles then timeout Start program = '/etc/init.d/httpd start' with timeout 60 seconds With pidfile '/usr/local/apache/logs/httpd.pid' Set alert httpd port 2812 and use address localhostĪllow localhost # Allow localhost to connect Set daemon 120 # Poll at 2-minute intervals What got me interested in monit, besides the fact that it's FOSS, was the easy configuration.

You may then install mmonit on a central monitoring management server, who will track all targets and report in the form of a nice 'green-light/red-light' web interface. It's not an IPMI or SNMP aware monitoring package, but it's simplicity in setup, and built-in services monitoring is appealing for the situations I needed to track. You should see the SSHD process on the web interface.I've been using a very simple monitoring package called Monit. Open a web browser and access Monit web interface with The is IP address of Raspberry Pi. Now check IP address of the Raspberry Pi: hostname -I Restart Monit service: sudo service monit restart Some of the other usage reports include: Kernal/temperature Filesystem and I/O Network traffic Apache/Mail. Monitorix got in-built HTTP so you can check the utilization and other stuff on the web. If failed port 22 protocol ssh then restartĬreate a symbolic link to enable configuration: sudo ln -s /etc/monit/conf-available/sshd /etc/monit/conf-enabled/Ĭonfiguration can be disabled as follows: sudo rm /etc/monit/conf-enabled/sshd A lightweight open-source utility to monitor the Linux server. etc/monit/conf-available/sshd check process sshd with pidfile /var/run/sshd.pid The second option is preferred because configuration can be enabled or disabled when needed. It can be placed in the following directories: For testing purpose, we will configure to monitor SSHD process that listens incoming SSH connections.įirst we need to create the configuration file. Monit has been installed and we can start to monitor processes. Once configured, restart Monit service to apply changes: sudo service monit restart Testing Monit

To enable it open the main configuration file of Monit: sudo nano /etc/monit/monitrcįind and uncomment the following lines: set httpd port 2812 andĪllow admin:monit # require user 'admin' with password 'monit' We can also stop, start and restart the Monit service: sudo service monit stopīy default web interface is not enabled. We can use the following command to check whether Monit service is running: sudo service monit status

#MONIT LINUX UPDATE#

Execute the following commands to update the package lists and install Monit: sudo apt update

#MONIT LINUX HOW TO#

This tutorial explains how to install Monit on Raspberry Pi. This tool provides web interface to view the status of processes or start, stop and restart them. Monit can also be used for monitoring files, directories, filesystems, network connections, and system resources. If process stopped to run, Monit can start it again. This tool allows to manage and monitor system processes such as Apache, MySQL, SSHD, and so on. Monit is an open-source process monitoring tool.
