Right then... Clean slate for this e-mail...
I've set up my snmpd.conf to include the following.
exec .1.3.6.1.4.1.6886.4.1.4 check_d_root /usr/local/nagios/libexec/
check_disk -w 15 -c 5 -p /
SNMPWalking through that gives me:
$ snmpwalk -v 2c -c management localhost .1.3.6.1.4.1.6886
SNMPv2-SMI::enterprises.6886.4.1.4.1.1 = INTEGER: 1
SNMPv2-SMI::enterprises.6886.4.1.4.2.1 = STRING: "check_d_root"
SNMPv2-SMI::enterprises.6886.4.1.4.3.1 = STRING: "/usr/local/nagios/
libexec/check_disk -w 15 -c 5 -p /"
SNMPv2-SMI::enterprises.6886.4.1.4.100.1 = INTEGER: 0
SNMPv2-SMI::enterprises.6886.4.1.4.101.1 = STRING: "DISK OK - free
space: / 29707 MB (90%);| /=3409MB;33100;33110;0;33115"
SNMPv2-SMI::enterprises.6886.4.1.4.102.1 = INTEGER: 0
Now, trying it with the -Ovq flag:
$ snmpwalk -Ovq -v 2c -c management localhost .1.3.6.1.4.1.6886
1
"check_d_root"
"/usr/local/nagios/libexec/check_disk -w 15 -c 5 -p /"
0
"DISK OK - free space: / 29707 MB (90%);| /=3409MB;33100;33110;0;33115"
0
Which is quite a lot closer to what we want. So I modify the two
snmpwalk commands in retrieve_custom_snmp. And I've made a boatload
of other fixes. I cannot believe how many mistakes I left in there :
( Should be a lot better now... Anywho, running the script now
results in:
$ ./retrieve_custom_snmp -H localhost -o .1.3.6.1.4.1.6886.4.1.4
DISK OK - free space: / 29705 MB (90%);| /=3410MB;33100;33110;0;33115
$ echo $?
0
Stuff that I had gotten wrong? I've already forgotten some things,
but here's the more notable stuff.
* No sed to strip quote from the output string.
* Had the wrong OID for the exit code. Used 100.0 (as indicated by
the man-pages), as opposed to 100.1.
* Used snmpwalk instead of snmpget.
Things should be a lot better now. Care to retry? The latest version
is up on my site right now. I'll also upload it to the Exchange in a
few minutes.
Cheers!
Thomas
