Hi All,
I wanted to create one Alert called Trigger PagerDuty but however, I need your comments or assist me in evaluating the below conditions from the Edit Alert Trigger wizard?

from https://PRDMON01-VM.domain.com/Orion/Alerts/Add/TriggerCondition.aspx
is that correct and make sense since the section I want to alert on: Volume is set up like that?
I want to get alert when any of these two incidents occurred:
- Disk space issue
- Server is unreachable.
thank you in advance.
