How to monitor if a specific program(NX-Witness) is running?

Gino_Schreuders · May 27, 2021, 12:17pm

Dear,

I’ve been trying to monitor wheter a program(NX-Witness)is active.

The intention is to get an alert when NX-Witness goes offline.
I already tried it myself but I can’t figure it out

Maybe one of you guys can help me out?

Kind regards,

Gino

Try something like this

alarm: check_if_NX-Witness_is_running
   on: apps.uptime
 calc: $celery
units: seconds
every: 10s
 warn: $this == nan || $this <= 30

vlvkobal · May 27, 2021, 1:13pm

Please check if you have the celery variable in the chart using the http://localhost:19999/api/v1/alarm_variables?chart=apps.uptime API call.

Gino_Schreuders · May 27, 2021, 1:32pm

Thanks for your quick response.

Now I have this:

I get an error but also when the program is running

Do you know how to adjust the config you send me to only get notified when the program is not running?

Kind regards,

Gino

I don’t see celery in the http://localhost:19999/api/v1/alarm_variables?chart=apps.uptime
Do I have to add this and if so, how can I do this?

Kind regards,

Gino

Have you checked the API call I sent you? Please show your "chart_variables":.

Just open it in your browser.

@Gino_Schreuders

When responding, use three backticks (```) before and after the code you were about to send.

vlvkobal · May 27, 2021, 4:18pm

I believe you should use

calc: $NX_Witness

You don’t have any variables/dimensions with the name celery and I don’t understand why you were trying to use that name.

OdysLam · May 27, 2021, 5:27pm

To be fair Vlad, you did have celery in the example
