relying on changes in the UI table is a bad idea: (1) potentially missing events: the UI displays paginated data; if my VMs are sorted by name, and I have 1000 VMs in my setup, and I just added a VM named "z", it will be added to the last "page" which is not displayed right now, so I wouldn't even be aware that something was added. (2) potentially "creating" "fake" events: changes in the displayed data in the UI can occur due to change in the Search query; if I have 50 VMs in my setup, and I initially had the "Vms:" search query, and now I change it to "VMs: name = a*", which results in displaying only 10 VMs, this may falsely hint on removal of 40 VMs from the system. > > 2, write UI plugin that uses oVirtJS to periodically check VM events not sure if this is referring to VM-related events in the code (e.g. hooking to the click on "OK" within the New VM / Remove VM dialog, or hooking to the "Success" callback of the action response, or something similar), or to the VM-related "Events" (i.e. the ones that are displayed in the GUI within the Events main-tab / bottom section). If the former: can be done, I assume, though not sure how complex it would be to implement the infrastructure for that. If the latter: this will "catch" actions that were performed either via the GUI or outside the GUI; in this case, it would probably be better to use an Engine extension API (solution "0" above) rather than a UI plugin, since it will be more reliable, will be active even when the GUI is not in use, etc. > > 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. > > Vojtech > > > ----- Original Message ----- > > From: "Oved Ourfali" <[email protected]> > > To: "Yair Zaslavsky" <[email protected]> > > Cc: "Koen Vanoppen" <[email protected]>, [email protected], "Vojtech > > Szocs" <[email protected]> > > Sent: Thursday, October 30, 2014 2:10:12 PM > > Subject: Re: [ovirt-users] webhook > > > > Hi > > > > CC-ing also Vojtech, the "father" of the UI plugins. > > > > Anyway, the only way to accomplish that via UI plugins at the moment is via > > adding a new "action menu item", that in the background deleted the VM, and > > reports to Foreman. > > I would be nice to have a "hook" for different UI action items, but it > > isn't > > available at the moment. > > There are plenty code samples for UI plugins, most of them available at: > > http://www.ovirt.org/Features/UIPlugins > > > > I must say that I'm not sure webhooks are the right approach for that, as I > > guess it is relevant only in environments in which one doesn't use the > > API/CLI/SDK.... > > but.. it will be a cool feature! > > > > Regards, > > Oved > > > > ----- Original Message ----- > > > From: "Yair Zaslavsky" <[email protected]> > > > To: "Koen Vanoppen" <[email protected]> > > > Cc: "Oved Ourfali" <[email protected]>, [email protected] > > > Sent: Thursday, October 30, 2014 1:44:38 PM > > > Subject: Re: [ovirt-users] webhook > > > > > > Oved - can we implement something like this using ui-plugins? > > > > > > > > > ----- Original Message ----- > > > > From: "Koen Vanoppen" <[email protected]> > > > > To: [email protected] > > > > Sent: Monday, October 27, 2014 4:06:40 PM > > > > Subject: [ovirt-users] webhook > > > > > > > > Hi all, > > > > > > > > Just a quick question.
