I’ve been looking through the applications and it seems like there is no way to store information from an application unless its numeric, and there’s no option to store data except via an rrd.
So as an example, say your application returns some statistics which are numeric and vary with each pool, but you want to store the application version number (which is a non-numeric string like myapp-v2.0.0-x86) and have it show on the rrd using a COMMENT. This information is basically static, so I wouldn’t care to store any kind of history in a round-robin database.
Is there any way to achieve this in the current implement of applications in librenms?
