I have a server that is running Solaris that has very stringent response times requirements.  The storage for this server is on a VMAX.  The application has come to me to see if there is a way to alert when the response time for one or more of their Luns reaches a certain threshold.  We monitor our storage using Unisphere, and there does not appear to be a way to alert on a single lun or a single storage group within Unisphere.  It appears to be all or nothing.  I am looking for ways to make this happen.  Any help would be appreciated.
