Usually you run the plugin with the comparative NTP source:

For debugging purposes, it may also be called with a more detailed output option (this mode is not suitable for continuous operation, but for testing purposes only).

C:> check_w32tm.exe host=ptbtime1.ptb.de debug

Host: ptbtime1.ptb.de
Warning: 5
Critical: 10
Timeout: 15
