We just purchased APM and I'm already having a minor issue getting an app monitor to work. I'm trying to set up monitoring on our Orion DB server and I'm getting some failed login errors. SQL is returning an error even though the account has sysadmin privileges and is assigned as a dbowner on all databases. The 'SQLServer:Buffer Manager' counters are all failing with 'Login failed for user xxxxxx'. I'm pretty sure it's a simple fix, but I searched and could not find the answer in the forums.
