There could be two issues here:  1) STP daemon stopped/hung and now its not collecting stp data anymore. Go to this location \Program Files\EMC\SYMAPI\stp\spa\DMF_XXX.XXX.XXX.XXX  and see if you have .tz files there. If yes, then probably STP daemon is collecting the perf data but not sending it for processing. If you dont see anything in there then look at the STP daemon logs or restart the daemon.  Wait for atleast 5 mins and see if its starts to collect the .tz files in that location.  2) The other possibility is that your SMAS app is hung or host has run out of resources.
Hi All,  I'm hoping someone can point me to a solution for a Unisphere issue in the Performance tab. In a nutshell, I can view old performance data but if I chart the past week, I only see data points up till July 17th. I see metrics when I view Real Time and I've restarted the services. No luck so far. See the attachment for an FE chart showing the issue.  Any help is much appreciated.  Thanks! Vic
