I thought I had told it to notify me every 16 hours. Over the weekend, a problem occurred and I was notified every 40 minutes or so. I can't help but think I must be missing a configuration somewhere.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>The service in question is monitoring free space on a filesystem. I want it to go into warning when there is less than 10% free and become critical when there is 0% free. From the event log, it seems like the state is going from CRITICAL to WARNING to CRITICAL, and every time it goes to CRITICAL, it sends me email.. but I can't figure out why it's going back into warning mode when the space free remained at 0%.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Part of the event log:</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>[02-17-2007 23:45:43] SERVICE ALERT: menc001;mc_vol001 Space;WARNING;HARD;4;DISK WARNING - free space: /Volumes/mc_vol001 0 MB (0%):</DIV><DIV>[02-17-2007 23:20:43] SERVICE NOTIFICATION: andy;menc001;mc_vol001 Space;CRITICAL;notify-by-email;DISK CRITICAL - free space: /Volumes/mc_vol001 0 MB (0%):</DIV><DIV>[02-17-2007 23:20:43] SERVICE ALERT: menc001;mc_vol001 Space;CRITICAL;HARD;4;DISK CRITICAL - free space: /Volumes/mc_vol001 0 MB (0%):</DIV><DIV>[02-17-2007 23:15:43] SERVICE ALERT: menc001;mc_vol001 Space;WARNING;HARD;4;DISK WARNING - free space: /Volumes/mc_vol001 0 MB (0%):</DIV><DIV>[02-17-2007 23:05:49] Auto-save of retention data completed successfully.</DIV><DIV>[02-17-2007 22:40:43] SERVICE NOTIFICATION: andy;menc001;mc_vol001 Space;CRITICAL;notify-by-email;DISK CRITICAL - free space: /Volumes/mc_vol001 0 MB (0%):</DIV><DIV>[02-17-2007 22:40:43] SERVICE ALERT: menc001;mc_vol001 Space;CRITICAL;HARD;4;DISK CRITICAL - free space: /Volumes/mc_vol001 0 MB (0%):</DIV><DIV>[02-17-2007 22:05:49] Auto-save of retention data completed successfully.</DIV><DIV>[02-17-2007 21:55:43] SERVICE ALERT: menc001;mc_vol001 Space;WARNING;HARD;4;DISK WARNING - free space: /Volumes/mc_vol001 0 MB (0%):</DIV><DIV>[02-17-2007 21:30:43] SERVICE NOTIFICATION: andy;menc001;mc_vol001 Space;CRITICAL;notify-by-email;DISK CRITICAL - free space: /Volumes/mc_vol001 0 MB (0%):</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" face="Arial" size="3"><SPAN class="Apple-style-span" style="font-size: 10.7px;"><BR class="khtml-block-placeholder"></SPAN></FONT></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" face="Arial" size="3"><SPAN class="Apple-style-span" style="font-size: 10.7px;">Relevant part of service definition:</SPAN></FONT></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" face="Arial" size="3"><SPAN class="Apple-style-span" style="font-size: 10.7px;"><BR class="khtml-block-placeholder"></SPAN></FONT></DIV><DIV> notification_options u,c,r</DIV><DIV> notification_interval 960</DIV><DIV> notification_period 24x7</DIV><DIV> check_command check_nrpe!check_disk!10%!0%!/Volumes/mc_vol001</DIV><DIV> }</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Ultimately I only want it to notify me when it's critical, not in warning, and I want the notification to only be sent every 16 hours (960 units, my unit is defined elsewhere as 60 seconds).
