Lots of performance alerts after upgrading XO to commit aa490
-
- I havent tested XOA yet. need a new trial period
- I have not changed anything but the updates for the host showing up in XO, and running the ronivay-script
- Testing the guide to use Git bisect
More errors
Seems I bult this XO on another host. not the same IP as the one I use now.

Well that didn't go as planned
@olivierlambert said in Lots of performance alerts after upgrading XO to commit aa490:
Hi,
- What's the result with XOA
latest
? - Have you changed Node version between the update?
- It would be truly helpful if you can manage to find the exact culprit (commit).
@julien-f wrote a guide to use Git bisect: https://xcp-ng.org/forum/post/58981
Since you know a good commit (here
f9220
) you should be able to quickly find the problematic code change- the f9220 build used node v18.20.4
The latest build 21bd7 use v20.17.0
Could it be that the newer node is faster than the old one?
f9220:
21bd7:
On 21bd7, if I increase frequency threshold to 65% it run backup without alert
Yes 21bd7 is a little bit faster but not that much that you have to increase from 40% to 65%
That's an increase by 62.5%Ran out of tests for today, but it was a nice way to spend a Saturday evening ;o)
- What's the result with XOA
-
Sigh... So that's the issue when one use 3rd party installers/repo. It's a lot harder to find the root cause, that's why we have put this big yellow warning in our doc:
https://xen-orchestra.com/docs/community.html
This is consistently making everyone losing precious time to understand a problem in the first place. Nobody (expect the 3rd party script provider) could guess that this script changed the Node version between "releases". You wouldn't have this result by just building from our doc.
So yes, that's very likely the reason here (Node 18 vs Node 20). Node 20 introduced different things that could trigger this behavior (adding @julien-f in the loop)
You could have saved an entire evening by using our official doc to install XO instead of a 3rd party script by the way. I don't blame you, I blame the fact that those 3rd party providers should be clearly contacted first before using community's time (and/or XO dev time, and/or mine). And it's not obvious enough since I'm repeating this around 5 times a month.

I'm retired, so for me it's Saturday all week.
Sorry I have wasted Your time.
I knew very well about the 3rd party debacle, but didn't think about it now
Now I'm Setting up a new VM, building it properly from the docs. -
Don't worry, it's not your fault, it's just that's the xxx time it happened
Still, it's interesting to had your feedback about the perf change with Node 20 (we read something about it recently)

One strange note when I get the alarms on e-mail during a full backup of my running XOAlert: vm cpu usage > 65%, XO 67,8%
End of alert: vm cpu usage > 65% SyncMate 0,3%
End of alert is the wrong VM, should be XO.
In Dashboard/Health it's OK, it says XO in both alert and end of alert ??Not a big deal for me, but I thought might as well report it

Might be a bug, worth pinging @MathieuRA

@ph7 I'm seeing the same thing as you, where I'm getting a mismatch between the server that is sending out the alert and then ending the alert. Just like you, it is actually the XO server that is truly the one that should be alerting. The second server (and it's always the same second server) is NOT having any issues with CPU or memory usage but is being drug into the alerts for some strange reason.
I'm currently on Commit 2e8d3 running Xen from sources. Yes, I know I'm 5 commits behind right now, and will update as soon as I finish this message. However, this issue has been going on for me for some time now and when I saw others with the same issue, I figured I'd add to the chain.
One other thing that happed around the same time this issue started... it seems the Average Length value for alerts are being ignored, or are at least being handled differently than they had previously. For example, I have my CPU alert set to trip if it exceeds 90% for over 600 seconds. Before the issue started, if I had a long running backup, my CPU would go over 90% and could sometimes stay there for an hour or more. During that period, I would get a single alert after the CPU was over 90% for that period of time and then Xen was "smart" enough that it would keep an eye on the average, so a brief couple second dip below 90% would NOT send out an "end of alert" and then a second "alert" message when the CPU went over 90% once again. This is not happening anymore... if the CPU spikes over my 90% threshold, I get an almost immediate alert message. The instant the CPU goes below the 90% threshold, I get an immediate end of alert message. If threshold goes back over 90%, even a few seconds later, I get yet another alert message.
This has had the effect where instead of getting a single message that spans the duration of the time the threshold is exceeded, where brief dips below were ignored if they were only a few seconds long, I am now getting an alert/end of alert/alert sequence for every seconds-long dip in CPU usage. Last night, for example, I received over 360 alert e-mails because of this, with many happening within seconds:
So... just confirming what @ph7 has been seeing... alerts are sending out from one server and a second sends the end-of-alerts, and for some reason the ability of Xen to average the alerts over the selected period of time so messages aren't sent out with every single seconds-long dip below the threshold is no longer working, as well.
Thanks!

Also ping @Bastien-Nollet & @MathieuRA since it seems also visible here

Hi. I am finally able to reproduce the end of alert issue.
However, I was only able to reproduce if I used the "ALL *" options and not by manually selecting the objects to monitor. Can you confirm that you are usingAll running VMs/Hosts/SRs
? -
@MathieuRA Yes, I can confirm I am using the All Running VMs and All Running Hosts (I am not using All Running SRs, but I never get alerts for those because I have a LOT of free disk space).
I did place an exclusion for one of my VMs (the one that was generating dozens and dozens of alerts) to cut down on some of that chatter, but even with one machine excluded, when I do get a report from one of the other VMs it still has the same issue: the proper VM will generate the alert, but an improper VM will be reported in the end of alert message.
So... as far as I can tell, we still have the issue with the improper machine identification and the Average Length field is ignored so a machine that pops over the threshold, then briefly under the threshold for a few seconds, then back over the threshold again will generate three messages (alert, end of alert, alert) in several seconds instead of looking at the average to make sure the dip isn't just a brief one.
Hopefully that makes sense.
Thanks again!

@JamfoFL As the bug appears to be non-trivial, I’ll create the issue on our end, and then we’ll see with the team to schedule this task. We’ll keep you updated here.

@MathieuRA
Yes, All running hosts and all running VMs -

@MathieuRA Thanks so much! I appreciate all the effort!

I added a new VM and put it in a backup job (which had a concurrency of 2) and got these new alerts:
ALERT: VM CPU usage > 80% XO5: 80.4%
End of alert: vm cpu usage > 80% HomeAssistant: 6,7%
It seems like the reporting has changed and is reporting the latest VM.The host alert is reporting in the same way
ALERT: host memory usage > 90% X2 🚀: 92.7% used
END OF ALERT: host memory usage > 90% X1: 11.3%
I have changed all jobs to concurrency 1 and I have not got any SR alert
