Enhancement: Show background coalesce and cleanup activities
-
How are patches applied to hosts through XO?
-
Via a XAPI plugin, so via a XAPI call in the end. No SSH involved.
-
If there's a way from the host to get information about the coalesce process, one could probably write a XAPI plugin to gather this information and offer it to XO (if XO devs decide that this kind of feature is a priority). However, I think it would be better if such information was provided by the XAPI itself.
So: it's probably not impossible to do, but not trivial either and involves different projects (XAPI, XCP-ng, XO).
-
Even if we do a XAPI plugin, there's no info in the coalesce mechanism progress, nothing. So it will probably require coalesce code improvement to report progress first.
-
I suppose currently the only information available is in logs? (And yeah we won't go parsing logs :D)
-
There's no progress in the log at all. We can just know it started, but there's no progress reported until it's done. We can't know how many % is done.
In short, it spawns a process doing the work, and that's pretty much it.
-
It might be interesting to write a piece of code in the coalesce code to get a progress, but that's... not trivial

From a user perspective it would be nice and useful to see the background stuff more upfront rather then hidden in a black box. But I understand it isn't trivial.
-
I totally agree. It would be nice, but out of reach due to other priorities right now. However, we are gladly open to contributions

Can the XAPI see if the coalesce process is running? Or is it not identifiable?
-
No it can't. As Olivier said, it spawns a process that currently does not report about progress status.
Edit: oh, maybe you just want XAPI to report whether there is coalesce happening, without any other details, based on the existence of the coalesce process?

Yes, as a start... maybe... that was the point of my question but I have a follow up question
-
XAPI could know, but it currently does not offer such information through its API.
-
Yep, there's basically nothing. It's more SMAPI related than XAPI in the end.
