Subject: [Nagios-users] Problems with passive checks
Hi!
I am unable to receive passive checks, or I am missing a piece..
CentralServer:
Debian testing, Nagios 1.2. External Commands are activated, passive
commands too
- Set up a Service:
define service{
name generic-service ; The 'name' of
this service template, referenced
in
other service definitions
active_checks_enabled 1 ; Active service checks
are enabled
passive_checks_enabled 1 ; Passive service
checks
are enabled/accepted
parallelize_check 1 ; Active service checks
should be parallelized
(disabling
this can lead to major
performance problems)
obsess_over_service 1 ; We should obsess over
this service (if necessary)
check_freshness 0 ; Default is to NOT
check
service 'freshness'
notifications_enabled 1 ; Service notifications
are enabled
event_handler_enabled 1 ; Service event handler
is
enabled
flap_detection_enabled 1 ; Flap detection is
enabled
process_perf_data 1 ; Process performance
data
retain_status_information 1 ; Retain status
information across program restarts
retain_nonstatus_information 1 ; Retain non-status
information across program restarts
register 0 ; DONT REGISTER THIS
DEFINITION - ITS NOT A REAL
SERVICE,
JUST A TEMPLATE!
}
define service{
use generic-service ; Name
of
service template to use
host_name testswitch
service_description Check
is_volatile 0
check_period none
max_check_attempts 3
normal_check_interval 1
retry_check_interval 1
contact_groups Test-Admins
notification_interval 120
notification_period 24x7
notification_options c,r
check_command check_if2_snmp
}
nsca.cfg:
server_address=192.168.100.76
allowed_hosts=127.0.0.1,192.168.100.178
debug=1
command_file=/usr/local/nagios/var/rw/nagios.cmd
alternate_dump_file=/usr/local/nagios/var/rw/nsca.dump
password=test
decryption_method=1
On the Remote host I have the same password and decryption method.
my Script
alteredbeast:/usr/local/nagios#cat check.sh
#!/bin/bash
send_nsca=/usr/sbin/send_nsca
send_nsca_cfg=/etc/send_nsca.cfg
nagioshost=192.168.100.76
host=$1
service=$2
plugin=/usr/local/nagios/check_disk
warn=10%
crit=5%
mountpoint=$3
output=`$plugin -w $warn -c $crit -p $mountpoint -m`
rc=$?
echo "$host\t$service\t$rc\t$output"|$send_nsca -H $nagioshost -c
$send_nsca_cfg
exit 0
When i try to send it via nsca to the central Server i get the following
result:
alteredbeast:/usr/local/nagios# ./check.sh testswitch Check /dev/hda8
0 data packet(s) sent to host successfully.
And on the Central Server the following lines in syslog:
Sep 17 10:45:42 localhost nsca[7421]: connect from 192.168.100.178
(192.168.100.178)
Sep 17 10:45:42 localhost nsca[7421]: Handling the connection...
Sep 17 10:45:43 localhost nsca[7421]: End of connection...
No entry appears in the Nagios Command File, but i can trigger a passive
Result via the web interface (Submit passive check result for this
service)
I don't know where to look know..
Jan
When i comment the second half of the "echo" line out
my result is:
alteredbeast:/usr/local/nagios# ./check.sh testswitch Check /dev/hda8
testswitch\tCheck\t0\tDISK OK - free space: /home 2701 MB (94%);|
/home=2700MB;2591;2735;0;2879
