I am running a Nagios Core 3.2.3 server on Opensuse Linux and I am attempting to obtain snmp results from an esx 3.5 server

I am trying to use the snmpwalk walk command to return a list of snapshot sizes but it only returns a single value.

This is the shell command on the ESX server-

snmp_snapshots.sh

Code: Select all

/usr/bin/find /vmfs/volumes/ -name '*delta*.vmdk' -printf %f' '%s'\n'

When I run it manually on the ESX box this is the return I get-

Code: Select all

testnag01-000001-delta.vmdk 16840704
testnag01-000002-delta.vmdk 167835648
testnag01-000003-delta.vmdk 151058432

So it looks like that bit is working fine.

however- when I run the following command on the Nagios server-

Code: Select all

/usr/bin/snmpwalk -v 2c -c public 10.10.0.20 .1.3.6.1.4.1.6876.57.101.2

It only returns a single value, and weirdly, its the second one-

Code: Select all

SNMPv2-SMI::enterprises.6876.57.101.2 = STRING: "testnag01-000002-delta.vmdk 167835648"

Any ideas why this isn't working?

Well it does seem to be working, as that is the second disk in your set. try it without the trailing .2, like this:

Code: Select all

/usr/bin/snmpwalk -v 2c -c public 10.10.0.20 .1.3.6.1.4.1.6876.57.101

Also, thanks for using code tags and such! I moved this to the nagios core forum as NSTI is a separate product.

Thanks a million sreinhardt, that has fixed the problem AND given me a ton of insight into how OID's actually work!!!
