check_traffic plugin

[Tedman Eng]

check_traffic uses snmp at its core.

Try the raw snmp commands on the host and troubleshoot that first:

snmpget -c <community> <host> .1.3.6.1.2.1.1.5.0

This should give you the FQDN as returned by the remote host.  

If not, then you have ACL's or some other network (ie routing/firewalling)
or host configuration (community string, host-firewall) issue preventing
access.

Once you have snmp working, check_traffic should work on that host as well.
Then it should be a simple matter of connecting it to nrpe to trigger
remotely via the nagios host.

Thanks for the reply

It appears to make no difference. I have noticed that if I use the CLI on
the Nagios server i.e.:

[root at tom]# /usr/local/nagios/libexec/check_traffic -H 123.123.123.123 -i 2
-b 1544000 -r Serial0/0 -w 70 -c 80

I get timeouts then no empty data

Timeout: No Response from 123.123.123.123
Timeout: No Response from 123.123.123.123
Total RX Bytes: 0.00 MB, Total TX Bytes: 0.00 MB<br>Average Traffic: 0.00
B/s (0.0%) in, 0.00 B/s (0.0%) out

I thought it might be a timeout problem but if finally do data is being
received then that would not appear to be the problem.

Does that give anyone any more ideas?

Thanks
