hi.

I'm having problems with nagios passive host checks. Every host state is sent to central server as "0" even if it is warning or critical. Service state has no problem, works like it should.

log from central nagios server
Host check

Code: Select all

Jun 24 17:00:46 srv-nag1 nagios: EXTERNAL COMMAND: PROCESS_HOST_CHECK_RESULT;HS-ai117;0;CRITICAL - Host Unreachable (10.41.12.117)
Jun 24 17:00:53 srv-nag1 nagios: PASSIVE HOST CHECK: HS-ai117;0;CRITICAL - Host Unreachable (10.41.12.117)

service check from central nagios server

Code: Select all

What is running on the passive/remote hosts that is ultimately sending the results via send_nsca? Is it a home-brew script of some sort? Have you verified that it is in fact exiting with the proper code?

Ok, I edited first post and entered slave/master on top of code.
So on passive/remote we run nagios server. Results are sent to main nagios server over ocsp_command, ochp_command.
On slave server everything looks fine host states are shown as they should be, UP,DOWN... But they are all transmitted to central server as state 0 (host up).

You can close topic. I fixed it with editing host_check script on slave server:

commands.cfg

Code: Select all

define command{
command_name host_check
command_line $USER1$/host_check  $HOSTNAME$ $HOSTSTATEID$ '$HOSTOUTPUT$|$HOSTPERFDATA$'
}

host_check

Code: Select all

#!/bin/bash
# host check
cmd="/usr/local/nagios/bin/send_nsca"
cfg="/usr/local/nagios/etc/send_nsca.cfg"
host=$1
srv=$2
result=$3
output=$4
/bin/echo -e "$host\t$srv\t$result\t$output\n" | $cmd -H 10.50.12.200 -c $cfg
