Check time offset of server with ntp server. Use local time if ntp-host option is not set.
|
|
SNMP gives a date with second precision (no milliseconds). Time precision is not very accurate.
|
|
Use threshold with (+-) 2 seconds offset (minimum).

|
=item B<--warning>
|
|
|
|
Threshold warning.
|
|
|
|
=item B<--critical>
|
|
|
|
Threshold critical.
|
|
|
|
=item B<--ntp-hostname>
|
|
|
|
Set the ntp hostname (if not set, localtime is used).
|
|
|
|
=item B<--ntp-port>
|
|
|
|
Set the ntp port (Default: 123).
|
|
|
|
=item B<--timezone>
|
|
|
|
Set the timezone of distant server. For Windows, you need to set it.
|
|
Can use format: 'Europe/London' or '+0100'.
