Cool, maybe something we could do in future as part of UX improvement,
i.e. change notification (push changes to client) to drive UI data update,
instead of periodic polling.

This can/should be done through the notification service,
currently it supports email & snmp traps ... but it could be extended (very
easily)

Agreed. For me, the "webapp side" is really an interesting option, since it
would mean that 3rd parties could write custom code that would consume our
existing Java/Engine "services" (assuming these could be exposed across WARs).
In other words, plug custom Java code into Engine ("inside-product
integration"),
as opposed to typical scenario where 3rd party system uses Engine REST interface
("outside-product integration").

Hm, Java class loaders have hierarchy, so if we put shared Java "services"
(ideally exposed and injectable as CDI beans) into class loader above specific
webapp (WAR) class loaders, it wouldn't be a problem. But I can be wrong here.

Agreed, that was a bad idea :) UI data is constrained by things like
search query, pagination, sorting etc. Scratch my previous idea.
As mentioned before, notification of relevant events occuring in system
should be the way to go. Either Engine will provide mechanism to notify
other systems (i.e. email notifier) or other system will poll/listen-to
changes in Engine (i.e. via REST API).
Idea for consideration, if every change to oVirt system would be sent
to some event bus, we could easily implement different notification
mechanisms (like websocket in addition to email), and web apps living
in Engine EAR context could also register to that event bus (imagine
WebAdmin servlet that listens for changes and pushes them to clients).

It was meant simply as polling Engine via oVirtJS / REST API.
But then again, any UI plugin-based solution has the drawback that
web GUI must be active (open) in order for plugin to be active.

Re: [ovirt-users] webhook
Whoow, just missed a couple of days I see... thanks everybody for your
already given support!! I will discuss this also with my colleague on
Monday. And I must say I'm impressed about all the fedback! This could be
indeed a very nice extension to oVirt, because I guess we are not the only
ones who are in need of this or will be in the future.
Thanks again!

Please allow me to step in as someone who worked on the extensions API as well,
There are more "missing bits" here.
You are referring to the "webapp side", but this is not enough.
We have also the engine side which has to become more pluggable.
In addition, we will probably need to handle all kinds of issues that rise from
our singletons at engine - class loading might be an issue here, no?
You don't want the "X-ton" (doubleton, tripleton, etc..) phenomena in your
setup - you don't want for example X instances of AsyncTaskManager.
I think that in general we should strive to turn engine into way more
pluggable/modular than it is now, imagine an "engine microkernel" (for those of
you who did not hear the term microkernel, I am referring you to jboss
architecture) - we should have a "thin microkernel" and the rest of the code
should be pluggable, using the extension API (and perhaps web fragments as
well).
What do you think?

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.

Re: [ovirt-users] webhook
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.

I agree that notification sounds like the best option, Although I would use the SNMP traps for that. If you already have a SNMP monitoring system you can catch the trap there and do your foreman magic. > > - Original Message - > > From: "Oved Ourfali" > > To: "Yair Zaslavsky" > > Cc: users@ovirt.org > > Sent: Thursday, October 30, 2014 3:10:12 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" > > > To: "Koen Vanoppen" > > > Cc: "Oved Ourfali" , users@ovirt.org > > > 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" > > > > To: users@ovirt.org > > > > Sent: Monday, October 27, 2014 4:06:40 PM > > > > Subject: [ovirt-users] webhook > > > > > > > > Hi all, > > > > > > > > Just a quick question.

Re: [ovirt-users] webhook
can't the event-notifications be used? notify some email on delete operation (not sure there is a notification for this today..) and hook on the email to run the script? - Original Message - > From: "Oved Ourfali" > To: "Yair Zaslavsky" > Cc: users@ovirt.org > Sent: Thursday, October 30, 2014 3:10:12 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" > > To: "Koen Vanoppen" > > Cc: "Oved Ourfali" , users@ovirt.org > > 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" > > > To: users@ovirt.org > > > Sent: Monday, October 27, 2014 4:06:40 PM > > > Subject: [ovirt-users] webhook > > > > > > Hi all, > > > > > > Just a quick question.

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!

[ovirt-users] webhook
Hi all, Just a quick question. Is it possible to set a webhook on the removal and creation of a new vm? So we can send to foreman a delete action when the VM is deleted... Kind regards, Koen ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
