do not enough $ARG$ for my service

[sacom01]

hi team,
I have a plugin with check 4 parameter : cpu, vms, io_read, io_write. Every parameter need check have -w and -c, so we have 8 arguments (4 -w and 4 -c)
When we check the service for client svr using ncpa, it will have 10 arguments : 4 -w and 4 -c and port and token.
But we have only 8 $ARGS like picture.

is there any way for this case? Now i have to hard code for fix 4 -w and 4 -c inside my code but it's very inconvenience.

Thank you.

Hi,

I can submit a feature request for this if you'd like. The recommended workaround to the limitiation of 8 arguments in the interface is to combine multiple arguments into one argument field.

If you need any assistance, please post the full check command, and we'll review the arguments.

Thanks,
Ben

i tried fix -p port and -t token to the command but facing error.

Hi,

That ought to work. Try wrapping the token in single quotes, 'mytoken', perhaps it's not getting passed over correctly.

I'm not familiar with the syntax on this plugin and was unable to locate it from Google but select the Run Check Command button, then cut and paste the command string into the CLI and get working from thee and then make adjustments in the CCM. There could be an error in the syntax.

If that's not working, please attach the plugin and I'll try to replicate it the best I can. Thanks, Benjamin

Okay, not sure why you are not able to view that attachment. I checked your account and it looks correct. Please follow the step in the article below to retrieve the full check command and post it to the ticket. Thanks,Benjamin

Hi,

Got the plugin and I was able to get this going. After putting the plugin in the NCPA plugin directory, I ran the NCPA wizard.

As you can see, it's only using one argument, but you could configure it differently. Here's the full check command.

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py -H 192.168.23.140  -P 5693 -t 'mytoken' -P 5693  -M 'plugins/unix_check_OSprocess.py' -q 'args=-wC 1 -cC 2  -wR 10 -cR 20 -wW 10 -cW 20 -wV 150 -cV 200'

NCPA uses python version 2 so its necessary to install python3 to run this. Then be sure to add python 3 to the npca.cfg file.

/usr/local/ncpa/etc/ncpa.cfg

Code: Select all

.py = python3 $plugin_name $plugin_args

More details on this in the thread below.

Let me know if you get it working. If you haven't done so already, it also will require installing python3 and psutil on the remote server.

HI sacom01,

For testing purposes, can you adjust the thresholds so you definitely are returning more than one line?

It could be changing states between running it locally and from XI.

I'm able to view more than one line of output in the XI interface.

Let me know what you find out. Also, what version of NCPA are you using, if it's really old it may not handle multi-line output. Post the output of the command below. Thanks, Benjamin

Code: Select all

curl -k -L -vvv 'https://<IP address>:5693/api/system/agent_version/?token=<token>&check=1'
