Error description
-
DETAIL OF PROBLEM: A defect exists where the order in which alert condition members are selected, affects whether or not the alert will ever be triggered. In an observed case: Some custom alerts were defined for the same Host+Pool+Nodes combination and different Performance metrics: response_time io_ rate data_rate read_data_rate write_data _rate peak_response time The important part to notice is that the custom alert (with several conditions defined on related resources), it will trigger when the alert is defined from higher to lower resource members like this: 1. Nodes 2. Pool 3. Host Connection Whereas the same alert does not trigger when the same conditions are combined but in the reverse order, from lower to higher resource: 1. Host Connection 2. Pool 3. Nodes RECREATE STEPS: Observe alerts not triggering when resources are ordered in certain ways, but will trigger when ordered in other ways. Problem as described by customer: Storage Insights custom alert with multiple conditions not triggering. Initial customer impact (low/med/high): low
