Nagios XI MRTG Module

[Johnsmit]

Hi,

I need some information on Nagios MRTG module, In a large growing monitoring environment, how does MRTG module in NagiosXI store and read the data for generating reports. Where does the MRTG module reads data from? does it create log or stores information for the work it does?

Thanks,

It stores RRD file in /var/lib/mrtg/ for the work that it does.

These files are references by the check_rrdtraf check commands for monitoring bandwidth levels as well as the Bandwidth Report.

Thanks for your response. Can we expect how large the RRD file grows and how exponentially it does?

The size of the RRD's are fixed from creation and the MRTG RRD's are 105160 bytes each.
