The only workaround I can suggest is to create a new dashboard for the performance graph and then add the performance graph to this dashboard using the Add to Dashboard link in the upper left side of the performance graph. Next go the dashboard that was created, select the 'hamburger' menu in the upper right and then choose Popout. This will give you a URL to the performance graph (via a dashboard) for the host or service.Is there a way to reference, say using a URL or some API, the NagiosXI peformance graph of a particular host or service? If not, how do I go about putting in a feature request for it
If you'd like I can certainly put in a feature request on your behalf. Please let me know.
