[Pkg-nagios-devel] Bug#609011: nagios-plugins-standard: check_snmp fails to parse SNMP string properly

[Thomas]

Package: nagios-plugins-standard
Version: 1.4.15-3
Severity: normal


Since version 1.4.15-3, check_snmp fails to recognize/parse strings properply
that are transmitted via SNMP.

My scenario: In the SNMP server, I defined exec commands whose return values are
checked via check_snmp. Example (omitting SNMPv3 authentication arguments):

 /usr/lib/nagios/plugins/check_snmp -H HOST -o
 .1.3.6.1.4.1.2021.8.1.101.11 -c 0 -P 3 -v -r 'FILE_AGE OK'

/usr/bin/snmpget -t 1 -r 5 -m '' -v 3 [authpriv] HOST:161
 .1.3.6.1.4.1.2021.8.1.101.11
 iso.3.6.1.4.1.2021.8.1.101.11 = STRING: "FILE_AGE OK:
 /mnt/backuppc/mount/kontrast-main/latest is 67478 seconds old and 1024 bytes"
SNMP CRITICAL - *67478* | iso.3.6.1.4.1.2021.8.1.101.11=67478

Behind iso.3.6.1.4.1.2021.8.1.101.11, there is the check_file_age plugin.

check_snmp from nagios-plugins-* 1.4.15-2 does it correctly:

iso.3.6.1.4.1.2021.8.1.101.11 = STRING: "FILE_AGE OK:
/mnt/backuppc/mount/kontrast-main/latest is 67666 seconds old and 1024 bytes"
SNMP OK - "FILE_AGE OK: /mnt/backuppc/mount/kontrast-main/latest is 67666 seconds
old and 1024 bytes" |
