I am sorry for spam. It's working fine!
I edited configuration files incorrectly. I use HPC2008 server and log
on under non-administrator user. When I try to edit file and save it,
the system saved file under my user account and main file under
administrator account was not edited and saved :-) But gmond uses it
file.
