We are in the midst of many nightmares concurrently: smoking servers, irreplaceable data lost, network latency, cold lunch, sore finger, you know the whole gambut at once. apologies to all. here is another entry from my logs. Each host is dependant on the previously numbered host (e.g. Marshall-McLuhan-0561SW2A_4-HS7 is the parent of Marshall-McLuhan-0561SW2A_5-HS7 who is the parent of Marshall-McLuhan-0561SW2A_6-HS7, etc. <DIV>why, once Marshall-McLuhan-0561SW2A_14-HS7 is determined to be UNREACHABLE (due to the failure of Marshall-McLuhan-0561SW2A_4-HS7), is the service checked on Marshall-McLuhan-0561SW2A_14-HS7?</DIV> [1034172479] HOST ALERT: Marshall-McLuhan-0561SW2A_14-HS7;DOWN;SOFT;1;CRITICAL - Plugin timed out after 18 seconds [1034172516] HOST ALERT: Marshall-McLuhan-0561SW2A_7-HS7;DOWN;SOFT;1;CRITICAL - Plugin timed out after 18 seconds [1034172552] HOST ALERT: Marshall-McLuhan-0561SW2A_6-HS7;DOWN;SOFT;1;CRITICAL - Plugin timed out after 18 seconds [1034172588] HOST ALERT: Marshall-McLuhan-0561SW2A_5-HS7;DOWN;SOFT;1;CRITICAL - Plugin timed out after 18 seconds [1034172624] HOST ALERT: Marshall-McLuhan-0561SW2A_4-HS7;DOWN;SOFT;1;CRITICAL - Plugin timed out after 18 seconds [1034172644] HOST ALERT: Marshall-McLuhan-0561SW2A_4-HS7;DOWN;HARD;2;CRITICAL - Plugin timed out after 18 seconds [1034172644] HOST NOTIFICATION: nagiosadmin;Marshall-McLuhan-0561SW2A_4-HS7;DOWN;host-notify-by-email;CRITICAL - Plugin timed out after 18 seconds [1034172645] HOST NOTIFICATION: Marco;Marshall-McLuhan-0561SW2A_4-HS7;DOWN;host-notify-by-email;CRITICAL - Plugin timed out after 18 seconds [1034172645] HOST NOTIFICATION: Kevin-NonCritical;Marshall-McLuhan-0561SW2A_4-HS7;DOWN;notify-by-epager;CRITICAL - Plugin timed out after 18 seconds [1034172645] HOST NOTIFICATION: Kevin;Marshall-McLuhan-0561SW2A_4-HS7;DOWN;host-notify-by-email;CRITICAL - Plugin timed out after 18 seconds [1034172646] HOST NOTIFICATION: Keith-NonCritical;Marshall-McLuhan-0561SW2A_4-HS7;DOWN;notify-by-epager;CRITICAL - Plugin timed out after 18 seconds [1034172646] HOST NOTIFICATION: Keith;Marshall-McLuhan-0561SW2A_4-HS7;DOWN;host-notify-by-email;CRITICAL - Plugin timed out after 18 seconds [1034172646] HOST NOTIFICATION: Ben;Marshall-McLuhan-0561SW2A_4-HS7;DOWN;host-notify-by-email;CRITICAL - Plugin timed out after 18 seconds [1034172647] HOST ALERT: Marshall-McLuhan-0561SW2A_5-HS7;UNREACHABLE;HARD;2;CRITICAL - Plugin timed out after 18 seconds [1034172647] HOST ALERT: Marshall-McLuhan-0561SW2A_6-HS7;UNREACHABLE;HARD;2;CRITICAL - Plugin timed out after 18 seconds [1034172647] HOST ALERT: Marshall-McLuhan-0561SW2A_7-HS7;UNREACHABLE;HARD;2;CRITICAL - Plugin timed out after 18 seconds [1034172647] HOST ALERT: Marshall-McLuhan-0561SW2A_14-HS7;UNREACHABLE;HARD;2;CRITICAL - Plugin timed out after 18 seconds [1034172647] SERVICE ALERT: Marshall-McLuhan-0561SW2A_14-HS7;Port Check-23;CRITICAL;HARD;1;Socket timeout after 10 seconds -----Original Message----- From: Bishop, Dean Sent: Thursday, October 10, 2002 1:04 PM To: 'nagios-users@lists.sourceforge.net' Subject: What the *&#( !!
