NCPA Issue

[mindspring]

Hi There,

I started getting this error message in monitoring an Artisan process using NCPA

Code: Select all

UNKNOWN: The node (process) requested does not exist. You may be trying to access the 'processes' node.

In the log file I can see the check running

Code: Select all

2021-07-05 09:00:29,478 8693 INFO ::ffff:<IPADDRESS> - - [2021-07-05 09:00:29] "GET /api/processes/?token=<PASSWPRD>&warning=40%3A&critical=20%3A&check=1&cmd=artisan&match=search HTTP/1.1" 200 3519 0.775105

Here is the configuration check from NagiosXI service configure:

Code: Select all

check_xi_ncpa!-t 'password' -P 5693 -M 'process/artisan/count' -w -50 -c -10!!!!!!!

Any ideas on this?

Hi!

Can you please try changing the check to:

Code: Select all

check_xi_ncpa!-t 'password' -P 5693 -M 'processes/artisan/count' -w -50 -c -10!!!!!!!

Ah thanks, i copied this from another service check and this seems to have worked:

check_xi_ncpa!-t 'password' -M 'processes' -w 4: -c 3: -q 'cmd=artisan,match=search' !!!!!!!

I wanted to tweak this alert a bit more by adding different checks for different artisan process types.

Code: Select all

For example, this has the different types in bold above, artisan queue:listen and artisan queue:work
Could I do something like the below?

Thanks

check_xi_ncpa!-t 'password' -M 'processes' -w 4: -c 3: -q 'cmd=artisan queue:listen,match=search' !!!!!!!
check_xi_ncpa!-t 'password' -M 'processes' -w 4: -c 3: -q 'cmd=artisan queue:work,match=search' !!!!!!!


UPDATE:
I tried the above method but I can't tell if it's working properly or not. The output of on NagiosXI looks like below:

Code: Select all

So it doesn't really show the full process. Any ideas?

Your modification appears to be working when I labbed this up. Try shutting down the artisan queue workers and see if the check stays the same.

Here's how to execute it from the Nagios XI machine's command line:

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py -H <your NCPA host IP> -t 'password' -M 'processes' -w 4: -c 3: -q 'cmd=artisan queue:work,match=search'

Many thanks, yes this is working.
