Manage Cisco Interfaces

[Patrick Proy]

Hi,

First have a look at the FAQ :
http://nagios.manubulon.com/wiki/index.php/Faq-url#No_usable_data_on_file_.2
8X_rows.29

Then read some doc : http://nagios.manubulon.com/snmp_int.html

Then, 
- Make sure that your check interval is similar to the default average time
(5 minutes) or change this with the "-d" option.
- add the "-g" option to get the 64 bits counters as the standard counters
aren't very accurate with Gigabit interfaces. 
- Use SNMP V2c ( "-2" option).
- Maybe give the C plugin version a try to enable caching ("-K") as it will
reduce the load on the Cisco and speed up execution time
(http://nagios.manubulon.com/package_c.html).

Regards,

Patrick

Thanks for the reply.

I have had this service running for the last 3 hours, and it still remains
in this state...

Hi Mike,

the plug-in check_snmp_int.pl will create a file in /tmp
"tmp_Nagios_int.ip.interface" for each interface you check. If you look at
one of these files you will see something like this: 
1193296121:2737857960:2609034930.
First one is a time stamp, the others are the counters for incoming and
outgoing octets you will also find via SNMP on your Cisco switch.

The problem is that the incoming or outgoing octets are counters and don't
contain the actual number of incoming octets for the last 5 mins or so. If
you run the plug-in it compares the returned values with the ones in the
temp-file and then calculates the incoming oder outgoing traffic.

When I used the plug-in first the state was UNKNOWN for the first 15 minutes
and then changed to an OK-state because the plug-in needs this time to
gather enough values to calculate the traffic.

Sorry for my english.

Hope this will help you.

Best Regards
Daniel
