Hi Team,

we are getting errors on some of our DB servers. we have installed NSC client on the server. Ping,cpu,physical and disk drive utilizations are working fine but for below MSSQL service we are getting error.

MSSQL Buffer Hit Ratio,MSSQL Cache Hit Ratio, MSSQL Connection Time - 18456, "Login failed for user 'nagios'.DB-Lib error message 20018, severity 14:\nGeneral SQL Server error: Check messages from the SQL Server\nDB-Lib error message 20002, severity 9:\nAdaptive Server connection failed (XXXXXXXX)\nDB-Lib error message 20002, severity 9:\nAdaptive Server connection failed (XX.XX.XXXX)\n").

MSSQL - Suspect DB - CRITICAL: Could not connect to dblib:host=XXXXXXXXXdbname=master as nagios (Exception: SQLSTATE[01002] Adaptive Server connection failed (XXXXXXXXXXX) (severity 9)).

We have checked the user create on DB and we have used same creds in the services creation.
