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.

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.

This guide outlines how to enable and monitor the CA health check. The EJBCA health check servlet offers several application-level points to be monitored, see Monitoring and Healthcheck for more information. Step 1 - Configure EJBCA health check service Apache version 2.4 front-end reverse proxy running on ports 80 and 443.List of the technology stack used in this guide:

By integrating EJBCA and Monit, you can monitor the health of your EJBCA application, application server, database management system (DBMS), as well as Apache HTTP Server (H TTPD), if applicable. With Monit, you can view the status of your monitored services in the web interface (dashboard) and configure email notifications for when issues arise. Monit is an open-source monitoring utility that can be used to monitor servers and trigger alerts in case of errors. The following instructions describe how to set up Monit to monitor EJBCA host variations.
