Hi dear,

I created the filter\_plugin that check if running process and return true or false. This is an example:

process\_name|get\_processes

I want to create this task:

**- name: start service**  
**shell: /usr/local/bin/my\_script**  
**when: process\_name|get\_processes is false**

But it seems to me that the conditional does not accept filter\_plugin.

Isn’t this what systemd is supposed to be for?  
If you deploy a proper systemd unit, you can use the service module.
