Usage of CGI files within a cluster

[stephan]

Hi forum users,

We are running a cluster of four Nagios nodes using Merlin to achieve high-availability and distribution.

Each out of the four servers is storing all related log information into it's own log files onto it's local hard disk. If we use the reporting functionality of Nagios it will process only the local log file, depending on the node where it's requested in the browser. By this functionality I mean trends.cgi, avail.cgi, histogram.cgi, history.cgi, summary.cgi, notifications.cgi and showlog.cgi. Where history.cgi is for now most important in our usage.

What I would like to achieve is use the Nagios interface using i.e. history.cgi and see results of all four nodes, so using more then only the local history data on the server itself. I guess these CGI's are using the nagios.log logfile to get this information? Or is there some binary storage of the results somewhere?

Maybe someone already found a solution to this goal or knows of a plugin/extension which is meant for it.

Thank you in advance!

One thing you could do in this case would be to passively push check results to a main nagios server vi NSCA. This would allow you to gather reporting information on the other clustered systems as well. This is covered here:

Is that along the lines of what you were thinking?
