Cannot access NagVis macros within my Context Menu

Hi,
I was looking at the macro defintions used in the hoover menu (/nagvis/share/userfiles/templates/default.hover.html) which looks like this when you hover one of the services:



Basically I wanted to do something really simple such as to try to output the value of the 'Summary Output' when the user clicks on the first option of the context menu (named "Start Data Flow"):



To accoumplish this, I checked the contents of the "default.hover.html" file:

        	<!-- END loop_child -->
    	</table>
	</td></tr>
	<!-- END childs -->
</table>


From the hover output, I am assuming that the macro name that I am looking for ('Summary Output') should be "[obj_summary_output]"

With that in mind, I created a copy of this default file and also of the associated css file and ended up with:
- pfc4ears.context.css (which is just a copy of the default.context.css file)
- pfc4ears.context.html with the following content:

So the goal is to simply test if I can get the summary output out, via the javascript alert() function, when the user clicks on the first option named "Start Data Flow"....

However, the macro comes up empty...does anyone know, why that and other macros get expanded (replaced by the corresponding values) correctly in the hoover window, but on the Context Menu window?

I also tried with [service_description] and that one outputs fine....so I am bit puzzled...

Thanks again for all your help,
Gizmo

You simply don't have the same set of macros in Hover- and Context-Menus. You have the macros available which are mentioned in the documentation.
It should be possible to merge both sets of macros to a general macro replacement mechanism with exactly the same sets of macros but this is not planned at the moment. I added a feature request for this.

Thanks for the reply! :)

I actually ended up, doing a query on Nagios using plain Javascript and then processing the resulting html code in Javascript as well, so that I could extract the summary output for service which I clicked initially...:)

It's a little bit dirty, but it works fine...(at least until all macros become widely available to both hoover and context menus).

thanks again for the reply and for adding this to the list of requested features.

Cheers,
Gizmo
