SLA calculation had changed in version 6.0.22 so maintenance periods are automatically excluded from SLA calculation, before they were not.

It would be great to have two options by adding “excluded downtimes” ourself for each calculation to get in the end two numbers:

1. SLA without maintenance period excluded
2. SLA with maintenance periods excluded

Our improvement suggestion: Zabbix reports both numbers or there is a setting to define if you want to exclude maintenance period automatically or not.
