Nagios Core 3.2.0 nagios-plugins-1.4.14 Ubuntu server 8.04.3 LTS Hi, I'm encountering problems to configure the notifications in case a server is no more responding to PING (ICMP). I don't understand why Nagios is jumping over steps when it's doing service-check "icmp". Here is the config : define host{ use generic-server host_name server1 alias server1 address the.ip.the.ip hostgroups prod-servers contact_groups group1 check_command check-host-alive check_period 24x7 check_interval 5 retry_interval 1 max_check_attempts 4 notification_period 24x7 notification_interval 60 notification_options d,u,r } define service{ use generic-service host_name server1 service_description ICMP check_command check_icmp!100.0,20%!500.0,60% max_check_attempts 4 normal_check_interval 5 retry_check_interval 1 notification_options w,u,c,r notification_interval 60 notification_period 24x7 } [...] define command{ command_name check-host-alive command_line $USER1$/check_ping -H $HOSTADDRESS$ -w 3000.0,80% -c 5000.0,100% -p 5 } define command{ command_name check_icmp command_line $USER1$/check_icmp -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$ -p 5 } [...] Here is an example of history that I get : <img style="font-family: courier new,monospace;" src="http://enacnagios.epfl.ch/nagios/images/critical.png" alt="Service Critical" title="Service Critical" align="left">[2010-02-16 11:33:13] SERVICE ALERT: server1;ICMP;CRITICAL;SOFT;1;CRITICAL - the.ip.the.ip: rta nan, lost 100% <img style="font-family: courier new,monospace;" src="http://enacnagios.epfl.ch/nagios/images/critical.png" alt="Host Down" title="Host Down" align="left">[2010-02-16 11:33:43] HOST ALERT: server1;DOWN;SOFT;1;(Host Check Timed Out) <img style="font-family: courier new,monospace;" src="http://enacnagios.epfl.ch/nagios/images/critical.png" alt="Service Critical" title="Service Critical" align="left">[2010-02-16 11:34:13] SERVICE ALERT: server1;ICMP;CRITICAL;HARD;1;CRITICAL - the.ip.the.ip: rta nan, lost 100% <img style="font-family: courier new,monospace;" src="http://enacnagios.epfl.ch/nagios/images/critical.png" alt="Host Down" title="Host Down" align="left">[2010-02-16 11:34:43] HOST ALERT: server1;DOWN;SOFT;2;(Host Check Timed Out) <img style="font-family: courier new,monospace;" src="http://enacnagios.epfl.ch/nagios/images/critical.png" alt="Host Down" title="Host Down" align="left">[2010-02-16 11:35:23] HOST ALERT: server1;DOWN;SOFT;3;(Host Check Timed Out) <img style="font-family: courier new,monospace;" src="http://enacnagios.epfl.ch/nagios/images/critical.png" alt="Host Down" title="Host Down" align="left">[2010-02-16 11:36:33] HOST ALERT: server1;DOWN;HARD;4;(Host Check Timed Out) <img style="font-family: courier new,monospace;" src="http://enacnagios.epfl.ch/nagios/images/recovery.png" alt="Host Up" title="Host Up" align="left">[2010-02-16 11:37:43] HOST ALERT: server1;UP;HARD;1;PING OK - Packet loss = 0%, RTA = 0.67 ms <img style="font-family: courier new,monospace;" src="http://enacnagios.epfl.ch/nagios/images/recovery.png" alt="Service Ok" title="Service Ok" align="left">[2010-02-16 11:39:13] SERVICE ALERT: server1;ICMP;OK;HARD;1;OK - the.ip.the.ip: rta 0.943ms, lost 0% Or later : <img style="font-family: courier new,monospace;" src="http://enacnagios.epfl.ch/nagios/images/critical.png" alt="Host Down" title="Host Down" align="left">[2010-02-16 11:42:03] HOST ALERT: server1;DOWN;SOFT;1;(Host Check Timed Out) <img style="font-family: courier new,monospace;" src="http://enacnagios.epfl.ch/nagios/images/critical.png" alt="Host Down" title="Host Down" align="left">[2010-02-16 11:43:13] HOST ALERT: server1;DOWN;SOFT;2;(Host Check Timed Out) <img style="font-family: courier new,monospace;" src="http://enacnagios.epfl.ch/nagios/images/critical.png" alt="Service Critical" title="Service Critical" align="left">[2010-02-16 11:44:13] SERVICE ALERT: server1;ICMP;CRITICAL;HARD;1;CRITICAL - the.ip.the.ip: rta nan, lost 100% <img style="font-family: courier new,monospace;" src="http://enacnagios.epfl.ch/nagios/images/critical.png" alt="Host Down" title="Host Down" align="left">[2010-02-16 11:44:43] HOST ALERT: server1;DOWN;SOFT;3;(Host Check Timed Out) <img style="font-family: courier new,monospace;" src="http://enacnagios.epfl.ch/nagios/images/recovery.png" alt="Host Up" title="Host Up" align="left">[2010-02-16 11:45:53] HOST ALERT: server1;UP;SOFT;4;PING OK - Packet loss = 0%, RTA = 0.64 ms <img style="font-family: courier new,monospace;" src="http://enacnagios.epfl.ch/nagios/images/recovery.png" alt="Service Ok" title="Service Ok" align="left">[2010-02-16 11:49:13] SERVICE ALERT: server1;ICMP;OK;HARD;1;OK - the.ip.the.ip: rta 0.948ms, lost 0% Someone any clue?
