The sample of proce_list.yaml definitions can't be parsed by process monitor.
# nova-compute
process_name: /usr/local/bin/nova-compute
start_command: systemctl start nova-compute
pre_start_command:
post_start_command:
restart_command: systemctl restart nova-compute
pre_restart_command:
post_restart_command:
run_as_root: True

It will occure an error like this:
2022-01-14 17:49:36.712 3801583 ERROR masakarimonitors.processmonitor.process [-] Exception caught: string indices must be integers: TypeError: string indices must be integers

The correct yaml config of process_list.yaml should be a array like below:

-
  process_name: /usr/sbin/libvirtd
  start_command: systemctl start libvirtd
  pre_start_command:
  post_start_command:
  restart_command: systemctl restart libvirtd
  pre_restart_command:
  post_restart_command:
  run_as_root: True

-
  process_name: /usr/bin/python3 /usr/bin/nova-compute
  start_command: systemctl start openstack-nova-compute
  pre_start_command:
  post_start_command:
  restart_command: systemctl restart openstack-nova-compute
  pre_restart_command:
  post_restart_command:
  run_as_root: True
