Nagios is a server monitoring infrastructure available to help Infrastructure and datacenter team monitoring day to day tasks. In the olds days we used to have to run horribly cryptics commands like sar, ps, du, df, and others, then parse the output with awk and sed and then figure out how to do something with the data. These commands were never standardized so scripts running under Solaris may not work as expected under SunOS! Things gradually evolved and Nagios came on the scene almost 20 years ago. Nagios is now used to monitor sites with hundreds of thousands of services and you can configure tiered monitoring if you need maximum scalability. Nagios is incredibly flexible, but its greatest strength is also its weakness. Its power comes from the fact that it is based on scripting, allowing you to monitor literally anything. It’s notification system is also based on scripts, so you can do whatever you like with the information, even restart services, clean old logs, or whatever. You can even download pre-written scripts to extend Nagios in all sorts of ways. Check the Nagios website for a repository.

>>> Prerequisites – Very basic requirement your company should be using RedHat or CentOS or SuSE, I recommend you purchase Nagios XI version.

SAP CCMS (our old school monitoring) is integrated part of SAP, which provide the low and intensive level monitoring of SAP servers including their hardware and software. It monitor almost all the the things in SAP. As Nagios is an open source tool working as an Enterprise monitoring server for data center and lots of Enterprises are using it. It give the good interface to administrators and have very good alerting options through mail or sms according to the escalation matrix. We can take predefine remedies action on affected service.

It can send alert through SAP as well. But I do this through nagios because I wants to do the
centralized monitoring and making the Nagios as an complete Enterprise Monitoring solution for
complete Data center.

I will cover end to end runbook to setup Nagios integration with –
