Nagios Support Forum

How can I get NagVis to show the performance graph of a service that is linked to a line, when you hover the mouse pointer over it?

Currently the popup just shows a summary status of the service, but I would like for it to also show the performance graph.

Hello @solarmon,

That's currently not supported the version of NagVis that's been integrated into Nagios XI, and I would recommend taking a look on the NagVis website. You can create gadgets that integrate into NagVis, and that maybe the option.

Thank you for your response.

That is disapointing to hear. I come from a Cacti and phpweathermap background and this feature (to display graphs on hover) was invaluable and helpful in diagnosing and troubleshooting.

Can you confirm what version of NagVis has been integrated with Nagis XI (5.6.6) and where/how would I check for this?

I see from the NagVis website that the latest stable is 1.9.14 released 2019-08-16.

Can the NagVis setup in Nagios XI be updated to the latest version? If so, is there a guide on how to do this.

Hello,

The current supported version in Nagios XI is 1.9.8. This is available in the system profile. You can try following these instructions for updating.

http://docs.nagvis.org/1.4/en_US/index.html

Please make backup of your Nagios XI server or take a VM snapshot before making any changes.

Hi,

When I check Admin -> System Profile - View System Info

under Nagios XI Components it shows:
There is no other references to 'nagvis' in that page. So I'm a bit confused with the version shown here as it is higher than what is actually currently available for NagVis. Or is this the Nagios XI module version that makes use of NagVis?

When I check Admin -> Manage Components it show the following for 'NagVis Integration':
I would still like to check/confirm what actual NagVis version is currently used/installed in our Nagios XI setup.

Hello @solarmon,

It's a bit confusing but the integration of NagVis is done using a component. A component is simply an add-on and users can develop their own add-ons.

In this case, the Nagios Integration Component is version 2.0.3, and the actual version of NagVis is 1.9.8.

@benjaminsmith

Thanks for the clarification.

I would suggest/request that the version of NagVis used is clearly stated in the component description.

@benjaminsmith

Actually, I just found out where you can actually see the NagVis version.

In Home -> NagVis there is a menu that appears on top right of the screen.

Select the following menu:

Need Help? -> NagVis Support Information

and the NagVis version is displayed in the Support Information window.

Hello @solarmon,

Thanks for pointing that out. Good to know! Also, if you ever need to learn more about a component, there is a download link in the Manage Components page, and within zip file there is typically a changelog available.

Hi @benjaminsmith

I looked in to gadgets, but I think this is only for producing graphics for objects display in NagVis - not for in the hover popups.

I looked in to NagVis hover templates. This initial looked promising, but I think the main issue is that there is no way (or I can't find a way) to point to, or reference, a specific host or service performance graph in Nagios XI?

I have seen NagVis tempates for accessing graphs generated by PNP and NagiosGrapher, bu tI think this are different to the NagiosXI performance graphs?

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?
