Unable to Monitor Error

by Aug 10, 2016

SQL Monitor is having problems monitoring two instances that are running on the same server.  It's having random outages with the message "Unable to Monitor."  I've checked the server and don't notice any problems with it.  All other instances are being monitored just fine.  I'm not sure what I can check to find out what is causing this error.

 

Thanks in advance for any help.
