Combine 2 SNMP Service Checks into a graph & calculation

[perric]

I searched and found this post... "Aggregate / consolidated graph of many links".

This looks exactly like what I need. I have a service that collects SNMP ifinoctets from a Cisco router's ethernet interface. And a service that also collects ifoutoctets. This provides inbound and outbound bandwidth values for each port, but I have been asked to consolidate this to one graph under reports and change the graph to show utilization as a percentage of the link size. So, I need to divide the value by the link size.

While the post mentioned above was helpful, there was a recommended solution proposed. Can I have assistance with how to do the recommended solution with variables, etc.? I have no problem modifying scripts, etc., but I am just not should how to begin.

What plugin are you using for this and can you post a service definition of two of the ports please?

Hello,

I use the check_snmp command with "-C xxxxxx -o .1.3.6.1.2.1.2.2.1.10.15" as a value for Inbound bandwidth and "-C xxxxxx-o .1.3.6.1.2.1.2.2.1.16.15" as a value for Outbound Bandwidth.

My hope was to see both values (inbound and outbound) with the calculation (dividing value by link size) on one "Performance graph" under Views, Service Details.

Thanks.

You could always write a wrapper script to run the two commands, grab the data and then output as you desire.

[perric]

Would you have an example script that would work?

No, but I could probably throw something together super quick. Show me the example output from the two checks please.

Thanks Bandit!

Sure. Do you mean the graphed output? If so, see inline below.

I actually meant the output on the command line so I can know what I have to parse out. Get me that information and I'll work on the script tomorrow as I am out of office today on a personal day.

Sorry. Do you mean this?

Inbound:

[root@cawlkl21 libexec]# ./check_snmp 10.197.0.11 -C public -o 1.3.6.1.2.1.2.2.1.10.15
SNMP OK - 3788642629 | iso.3.6.1.2.1.2.2.1.10.15=3788642629c

Outbound:

[root@call1 libexec]# ./check_snmp 10.197.0.11 -C public -o 1.3.6.1.2.1.2.2.1.16.15
SNMP OK - 4243923118 | iso.3.6.1.2.1.2.2.1.16.15=4243923118c
