Severity: important
snmpd can be queried for customized "extend"s.
A configured extend like
extend avail_mem /usr/local/bin/check_avail_mem.pl
can be queried as
snmpget -c public -v1 ds9 'nsExtendOutput1Line."avail_mem"'
NET-SNMP-EXTEND-MIB::nsExtendOutput1Line."avail_mem" = STRING: 749764
If you try to query this with check_snmp like
check_snmp -H $HOSTADDRESS$ -C public -o
'nsExtendOutput1Line."syslog-idletime"'
this results into
Could not open pipe: /usr/bin/snmpget -t 1 -r 5 -m ALL -v 1 -c public
ds9:161 nsExtendOutput1Line."syslog-idletime"
Unfortuantely, check_snmp contains code in popen.c that does not allow any "
chars in
the command line and bails out with above error.
I fixed this by commenting out the follwing block:
