@DaanHoogland Thanks for the usage service logic
Please find the steps that I followed
1. Have a CloudStack environment (4.20.2) with 2 mgmt servers (mgmt1 and
mgmt2)
2. Have the CloudStack usage service running on both management servers
3. Change the global setting
usage.stats.job.aggregation.range to 5
usage.stats.job.exec.time to an upcoming timestamp
Restart the cloudstack usage service
Check the usage log on both the management servers , the following message
should be present
```
2026-01-09 08:56:44,369 INFO
[cloud.usage.UsageManagerImpl_EnhancerByCloudStack_4ff0bd12] (main:[]) (logid:)
Usage is configured to execute in time zone [UTC], at [09:00], each [5]
minutes; the current time in that timezone is [2026-01-09T08:56:44+0000] and
the next job is scheduled to execute at [2026-01-09T09:00:00+0000]. During its
execution, Usage will aggregate stats according to the time zone [GMT] defined
in global setting [usage.aggregation.timezone].
```
4. Stop the cloudstack-usage service on mgmt1
```
service cloudstack-usage stop
[root@ref-trl-10556-k-Mol8-kiran-chavala-mgmt1 ~]# service cloudstack-usage
status
