Problems with passive checks

[Tedman Eng]

Try changing your check.sh script's echo line to echo -e to parse the "\t"
properly.

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
