Hi, Nixon
What you are experiencing is most likely the same as Andrei (see
https://lists.apache.org/thread/ltsw9tkkxv6pl2tr9r4q5m34xwlxxbqg), by
default, the API used by the UI to list the VMs also lists the VM's
metrics; since you have 100+ VMs, it is understandable that it would
take some time to list all of those metrics. This behavior has been
discussed and changed with PR
https://github.com/apache/cloudstack/pull/8782. On the next minor
release (4.19.1) there will be a configuration to let you change the
behavior of the `listVirtualMachines` API so that it does not return the
metrics by default.
Also, if you have too many metrics collected, you might run into the
issue that is described here
https://github.com/apache/cloudstack/pull/8740, where due to the amount
of metrics that ACS tries to delete in a single query, the query always
times out, snowballing into a huge amount of metrics on your DB, slowing
you down even more. The linked PR solves this adding another
configuration to limit the amount of metrics deleted per query,
hopefully it will be in by 4.19.1.0. Until then, if you notice that the
metrics are not being deleted, you might have to manually delete the old
ones on the DB.
Best regards,
João Jandre

Hello,
I am using ACS 4.18.0.0v in my production environment, and more than 100
instances, including Kubernetes instances, are running on my setup. The
user interface appears to be stuck in the loading phase when you click on
the instance page; you will need to wait five to ten minutes for the
instance list to appear. Not just the instance page, but also the place
where instances are listed out; for example, adding port forwarding or
listing instances running in VR everywhere they are the same. Is anyone
facing the same issue?
I checked the management log and saw that there was no error message and
that the management server's resource utilization was normal. . If someone
could provide some troubleshooting steps to identify the issue, that would
be very helpful.
