Package: munin
Version: 1.4.5-3
Severity: normal
Tags: upstream

This bug was originally reported in Ubuntu here:

https://bugs.launchpad.net/ubuntu/+source/munin/+bug/851625

and forwarded to upstream here:

http://munin-monitoring.org/ticket/1143

I am reporting it here in Debian as well so that Debian users who
experience this issue will know its status upstream.

Including the full bug description:

---

The plugin actually supports 32 bit counter as well as 64 bit counter. However, 
if the snmp server you are connecting to does not support 64 bit byte counters, 
snmp__if fails.

When I tried to the snmp server which supports only 32 bit counter, the plugin 
returned as follows:
#munin-run snmp_hostname_if_1
recv.value noSuchObject
send.value noSuchObject

Here is an example of problems I found in the code.

# from line 244
if (defined ($response = $session->get_single($ifEntryIn64Octets) ||
                  $session->get_single($ifEntryInOctets))) {
    print "recv.value ", $response, "\n";
}

In these lines, "$session->get_single($ifEntryIn64Octets" is supposed to return 
undefined value if the server doesn't support 64 bit counter. However, it 
actually returns "noSuchObject".

So, these lines should be fixed like this:

if (defined($response = $session->get_single($ifEntryIn64Octets))){
 if ($response eq 'noSuchObject'){
  # 64 bit counter is not supported
  $response = $session->get_single($ifEntryInOctets);
 }
} else {
 # No response
 $response = 'U';
}
print "recv.value ", $response, "\n";
