(v3.2.0 with SLES 10 SP2) As a consequence I'm setting up the plugin check_ntp_time to ensure that the clock on the nagios monitoring box doesn't drift too far ahead (or behind.) without telling us so that we can do something about it. For the threshold for warning and critical, I was thinking of -w 30 and -c 60 - would this seem sensible ? And also, if the alert did become critical because the drift was greater than 60 seconds what would be a sensible way of fixing this without human intervention. I thought that an event handler might be the way to go here that would restart the ntpd daemon. I'd be interested to know what your thoughts are / whether there is a better way ? thanks, deborah *************************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
