GaOrtiga opened a new pull request, #13561:
URL: https://github.com/apache/cloudstack/pull/13561
### Description
Currently, KVM metric collections are performed for each Management Server
independently. This process sends command to the Agents, requesting a
collection of VM metrics. The Agent receives the command, collects the current
metrics, compares it with the previous collection, and sends the final results
to the MS that requested the metrics. Finally, the MS saves the data to the DB.
The new metrics are compared to the previous metrics collected, regardless
of the MS that triggered the process. Thus, the collection interval depends on
the interval between the Management Servers, and not the interval defined in
the configuration. This does not affect the authenticity of the data, however,
it disregards the configured timeout.
To prevent this situation, the source code has been adjusted, guaranteeing
that the MS only sends metric collection commands to hosts connected to it.

#### Bug Severity
- [ ] BLOCKER
- [ ] Critical
- [ ] Major
- [X] Minor

occured normally for the VMs on hosts connected to the MS.
- For the remaining hosts, the collection did not occur.
