Hi,

change to
when: htop_is_running.stdout == ‘0’

It might be cleaner to use pgrep instead for process check. Then you can use something like this:

   tasks:
     - name: Process check
       command: pgrep httpd
       register: httpd_check
       ignore_errors: true
          - debug:
         var: httpd_check.failed

     - name: restart httpd if down
       systemd:
         name: httpd
         state: restarted
       when: httpd_check.failed

What's wrong with asserting that the service should be started?

- systemd:
     name: httpd
     state: started

- systemd:
name: httpd
state: started

For the vast majority of cases that should work (the apache service in major
distros being such a case).

Sometimes you do get an edge case where the PID check in the unit file is not a
good enough check for the health of the service as a whole.

when: htop_is_running.stdout == ‘0’ did not work

command: pgrep httpd

My question is why the following not working
when: status_httpd.stdout_lines == 0

ok: [mhost1] => {
“status_httpd.stdout_lines”: [
“0”
]
}

Thanks

If the 'when' condition, you are effectively working in python land.

Here you are making probably two mistakes:
  - 'stdout_lines' is an array. 'stdout' is a string.
  - you are comparing strings to numbers

sorry. I take it back my words

the following change is working

when: htop_is_running.stdout == ‘0’

Thanks
