Need to place pgpool logs on separate directory

I want to place pgpool logs on a separate directory rather than in a syslog file. So I changed the below parameters, but still logging information are being written to the syslog file.  Any idea or suggestion why this behaviour?

Tried all the below combinations, none of them works

1.

log_destination = 'stderr'  

syslog_facility = 'LOCAL0'

syslog_ident = 'pgpool'

logdir = '/data/pgpool'

2.

3.
