Nagios Support Forum

Hi there,

We currently retrieve status information via JSON queries to our Nagios XI installation to give us status information on our monitoring screens, and it works great.

I would like to now extend this to displaying graphing data, and so my question is; is there any way to access the underlying performance data via a JSON type query ?

Thanks,


Matthew

Hi there,

I had already spotted that one. It gives me the current performance data for the Nagios server, I was more interested in getting the historic performance data for a service.

Thanks,


Matthew

The historic performance data actually isn't stored in the databse, but rather RRD files. I don't think there is a way to access this information through the API.

The information can be pulled from the /usr/local/nagios/share/perfdata/ directory on the XI server, though.

You could use a command similar to this to grab it, rrdtool fetch /usr/local/nagios/share/perfdata/myhost/myservice.rrd AVERAGE -s <starttime> -e <endtime>
