[ovirt-users] webhook

[Vojtech Szocs]

Hi,

if I get this correctly, you'd like to be notified when certain event
happens (VM created/deleted/etc.) and react upon that. I see multiple
possible approaches here:

0, improve Engine extension API (refer to Alon Bar-Lev for details)
   - if extensions can be packaged as JARs and these JARs could include
     web fragments [1] it would mean the possibility to deploy custom
     servlets onto existing Engine instance (in context of webapp that
     processes extensions)
   - your custom Java servlet could query REST interface (or be notified
     once something happens, but AFAIK we don't have that implemented yet)
     and do whatever logic is needed
   - once I asked Alon about ^^ but never got response from him
   - IMHO this would be a nice way to deploy custom Java code on Engine

[1] https://blogs.oracle.com/swchan/entry/servlet_3_0_web_fragment

1, improve UI plugin API
   - add "VirtualMachineDataLoaded" event fired upon each refresh of
     VM data in UI table (generalization -> "{Entity}DataLoaded")
   - this is similar to existing "{Entity}SelectionChange" events

2, write UI plugin that uses oVirtJS to periodically check VM events

The disadvantage of 1, and 2, is that WebAdmin GUI must be open.
In any case, if you'd like to explore the possibility of doing this
via UI plugin, I'm here to help.
