I want to get Cacti Monitored DataSource Values

[manickkarthik]

Hi Community

I am using cacti to monitor one server. Cacti stores the monitored values into RRD File. But i want to get that value in PHP Variables.

Thanks in Advance

Sounds like you need to roll your own code to extract the data dynamically from the rrd file...

That is true, but you can use the rrdtool_fetch function in Cacti to do it..

I want to get the cacti monitored values before put it into RRD file. please give the cacti monitor file name where we can get that values.

Thanks

I think the poller_top hook in the plugin architecture does what you want.

Grab a simple plugin like Links to see how the plugins work, and take a look at the hook documentation at docs.cacti.net

Oops. I meant poller_output, not poller_top. That hook gets called once per device as the poller runs, with the data that will be going to the rrd files.

I'm just trying to figure out what the format is exactly myself for the data though. Threshold has some example code to read the structure.
