Yep.
<metric> regex <expression>
Examples:
hostname regex (core1|core2|edge1|edge2)
bgpPeerRemoteAS regex (6500[1-3]|3945|12387)
etc.
I like to use this regex tester when building more complicated expressions: https://www.regexpal.com/
The tests themselves are still AND/OR, though. I saw a picture a while back of an updated alert system that includes the ability to nest logic, creating more complex alerts. Unsure of status.

Hello,
Is it possible in Alert checker under the same field to add value with logical OR, for example:
Under "Device Match" - group includes Nexus|ASRS|ISR
and the same question on Entity match.
Thanks
