Marc, we use action handler scripts to schedule downtime in this case. As an example, a downtime for a service is scheduled for 6 minutes if $1 is CRITICAL and $2 is HARD. That is the maximum amount of time this service needs to be restarted (via nrpe, in the same script): /usr/bin/printf "[%lu] SCHEDULE_SVC_DOWNTIME;host5.example.com;Host5;`date +%s`;$((`date +%s` + 6 * 60));1;0;0;serveradmin;Service on Host5 is restarted\n" `date +%s` > /var/spool/nagios/nagios.cmd Following <http://old.nagios.org/developerinfo/externalcommands/commandlist.php>, you can send the command DEL_SVC_DOWNTIME if the service is up before the scheduled downtime ends. The same should be possible with SCHEDULE_HOST_DOWNTIME or SCHEDULE_HOST_SVC_DOWNTIME and DEL_HOST_DOWNTIME. So Nagios will still see the downtime, but since it is marked as scheduled downtime, your statistics may look better ;-) HTH Werner - -- -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://www.enigmail.net/ iEYEARECAAYFAlA/SnEACgkQk33Krq8b42NDRACaA1Gr5NS/FqWEWaP/qrb/ST6k HocAni3ka4fC+tilNYBefzlz0IFAsDT7 =fZIL -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
