Graphs and thresholds for custom command

[jpipitone]

I have a python script that checks an F5 BigIP's current total connections per second, and returns a value between 0 and 500. The syntax is as follows:

Code: Select all

check_bigip_tps.py -H 10.9.0.0 -C public -T 500

The custom nagiosxi command is as follows:

Code: Select all

$USER1$/check_bigip_tps.py -H $HOSTADDRESS$ -C $ARG1$ -T $ARG2$

Results are returned like so:

Code: Select all

Transactions Per Second is now 1 (0 of 500)

Is there a method to allow graphing after results are returned, or does the check script have to support this? Also, is there a way to set a threshold, so 200 connections is a warning, and 300 is critical?

Yep, you would have to build in handling for performance data, which is not all that hard. Can you attach your script here so we can take a look?

I'd take a look at this for perf data:

Sure, attached it here.

How about thresholds?

[tmcdonald]

Thresholds are explained in the link as well. They are the "warn" and "crit" values:

Code: Select all

'label'=value[UOM];[warn];[crit];[min];[max]

[jpipitone]

If the plugin doesn't allow the use of parameters for threshold values or performance graphs, are you saying that there's a way to implement them without modifying the code in the python script, or will I have to implement some logic?

I am still at a loss as far as where to start.

You would have to modify the script. but, I made an attempt to add the perf data for you, you can give it a whirl...

Thank you - the graphing works!

I'm curious to know how I can add the thresholds now. Basically, this would be how we'd want it configured:

Critical: 150
Warning: 75

I'll try to get this going as well.

You will need to add a few logical blocks to the script to check the results against the configured thresholds. You will also need to add the threshold getopts for the script and alter the perfdata output to use the thresholds.
