I have 40 sql servers running sql 2000, 2005, 2008 mostly the latter; running on W2K3, and W2K8R2 (mostly the latter). I have added them to the application group for sql servers; they also are running the Profiler Agent 4.12; the appropriate port is provided for whichever instance is on the sql server -- for security reasons the sqldba uses ports that are not the default. However, less than half of the servers provide results other than disk, cpu, memory, .. in other words there is no data regarding the databases themselves. I have burned out a number of brain cells trying to troubleshoot the problem. Has anyone else had the same issue and been able to resolve it?
