Additional Information

After time change this weekend our threshold alert (<-90%) for Utilization In has triggered two days in a row.  Does the baseline adjust for the time change?
No. I can submit an enhancement to correct this if you like. 

If not, what do you suggest we do while the baseline normalizes?
You could raise the threshold or shut it off other then that not much can be done. 

Will that take 3 months?
The default for the maximum baseline is 12 weeks so for the baseline to completely correct again is would take 12 weeks. However we believe it would take at least several weeks to get back close to normal after a time shift. You can check what baseline maximum is set to in your environment by going to http://DA_host:port/rest/sdshbaselineconfig.
