Hello @NagavardhanGuntupalli-6792 ,

Thanks for reaching Microsoft Q and A platform.

The right threshold configuration for DIP availability is 100, 100 means healthy, when the health goes below 100 you would get an alert.

Resource health status Description Available ==> Your standard load balancer resource is healthy and available.

Degraded ==> Your standard load balancer has platform or user initiated events impacting performance. The metric for data path availability has reported less than 90% but greater than 25% health for at least two minutes. With this status, you experience moderate to severe performance effect. Follow the troubleshooting RHC guide to determine whether there are user initiated events causing impacting your availability.

Unavailable ==> Your standard load balancer resource isn’t healthy. The metric for data path availability has reported less the 25% health for at least two minutes. With this status, you experience significant performance effect or lack of availability for inbound connectivity. There may be user or platform events causing unavailability. Follow the troubleshooting RHC guide to determine whether there are user initiated events impacting your availability.

Unknown ==> Health status for your load balancer resource hasn’t been updated or hasn’t received information for data path availability for the last 10 minutes. This state should be transient and will reflect correct status as soon as data is received.

Please change the Threshold to 100, and manually make the probes go down to check if the alerts are working if this is your test environment.
