Nagios Support Forum

Somehow I was under the impression that Nagios XI recorded performance data to a MySQL database. This does not seem to be the case. I found a lot of RRD files with the performance data. Is there a change I can make (easily if possible) that will use MySQL or something other than RRD for performance data recording? I have a need to update old values in the database and doing so with RRD files is very cumbersome and prone to errors due to timing. Thanks.

We can certainly put in a feature request for this, but at present this is not an option. Some of our plugins rely on the RRDs to function, and re-writing them to work with either the RRD or a DB would take some time, not to mention rewriting XI functions themselves. The RRDs never grow in size, which is another reason we like them because you can very easily calculate how much space will be used.

Thank you very much for the quick reply. I guess I will have to do the updates to the RRD data by hand for now. If anyone knows of a good reliable (library or script) way of doing this please let me know. Thanks.
