We have an important threshold profile that is not alerting when devices exceed the specified limits.
Thresholds not being generated for memory profile.
Thresholds not being generated for CPU Utilization.
Thresholds not being generated for Rules using Aggregated metric data.
Thresholds not being generated at the device level for Aggregated CPU Utilization.
All supported DX NetOps Performance Management releases
The Groups tied to the Threshold Rules Threshold Profile have Devices as members but do not have the "Include the children of managed items" option enabled.
For the Group(s) applied to the Threshold Profile that contains the problem Rule, ensure the "Include the children of managed items" checkbox is checked off.
This allows the Threshold Rule to see and find the necessary component items under the parent device for evaluation of it's metric data compared to the threshold rule.
