Number of alerts generated in alert inbox are more than data collection interval of the metric/alert
We have a Bad dialog response time (instance level) alert in which dialog response time metric has data collection and granularity both set for 5 minutes.
But when checked the alert in alert inbox of technical monitoring work center, i can see start time and end time being same but the number of alerts generated are more... How is this possible??? when the data collection itself is 5 minutes.
My way of looking at the issue - If we have 3 alerts then the start and end time should be in difference of atleast 10/15 minutes as the data collection of the metric itself is 5 minutes.. Can someone explain this strange things happening in alertinbox/metric functioning.
FYI - Issue is not specific to Bad dialog response time alert but also for other alerts as well.
