Change https://gist.github.com/ze-gitan/7c941eef1906d37f0310#file-master_status-py-L6

check=format("{params.pid_file}/Custom.pid")

for

check=format("{pid_file}/Custom.pid")

And if that is still not working then get the path with glob.glob.

check=format("{pid_file}/Custom.pid")
check_process_status(glob.glob(check)[0])
