For how long RRD files accumulate the performance data in Nagios ? Is the duration configurable?

[sreinhardt]

This sounds more like an XI question, but yes it is configurable. To the extent that you can change the length of time to keep various times for check results, 1 day of 1 min checks or only 5 min of 1min check, on a per rrd file\check basis. The amount kept by default should be able to be gathered from running rrdtool on the individual rrd files.

I would take a look at this plugin:

RRD files are automatically created when a host or service which returns perfdata is created. The file size is automatically determined based on the data it will be logging and as new data is logged, at a set period the old performance data is compressed down further and further to maintain the file size.
