To monitor the vSnmp.Manager service, you can use the vSnmp.Trace utility, which can be found in the vSnmp installation directory.
On startup, the trace utility connects to vSnmp.Manager and displays log messages, device value changes, received traps and status updates.
To connect to a vSnmp.Manager service on another machine, pass the address or hostname of the remote machine on the command line: vSnmp.Trace.exe <host>.
To get more information on the vSnmp.Trace utility, enter help on the vSnmp.Trace prompt.
