Dynamic Thresholds Not Generating?

[awjudge]

This might be a simple one...

I have added an Exchange plugin to a Hyperic adapter running on our Exchange server.

I have added the resource to vCOps, and data is being collected fine.

I have checked the resource to make sure that the Dynamic Threshold checkbox is enabled for that resource.

The system has been collecting metrics for a few days, but I still don't see the grey bar that represents the normal range of values. I think this is affecting the health metric for the resource...

Am I missing something? I have tried to run the DT Calculation Info in the Admin/Support menu, and it completes without error.

Can anyone tell me what I'm missing?

Thanks!

Can anyone confirm for me the methodology of the dynamic threshold generation.

My understanding is that every 24 hours, the thresholds are re-calculated. A grey bar should appear to show the 'normal' range for a metric.

Sometimes there are yellow boxes around metrics that are outside 'normal' but there are red boxes too. I couldn't find anything in the documentation that explains this functionality well.

not exactly

the first time you have introduced a metric, it will take a week (7days) for DTs to come up.
