The heartbeat/pacemaker packages have their own monitor/restart services, and you don't want two different services fighting each other to restart applications. 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.

Monit log file monitoring license#

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. The benefits of log file monitoring include: Monitor log data for any particular event or pattern Identify errors for any failure Improved. The log file monitor tracks errors in logs generated from applications on Windows and Linux servers. If failed checksum then exec '/watch/dog' Analyzing and tracking issues in a log file during emergencies can be a challenge for administrators. # 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.

Monit log file monitoring install#

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. I've been using a very simple monitoring package called Monit.
