Folks,

I have got some basic questions to be clarified. Please don't mind if it sounds trivial to you.

I have a cacti setup with boost enabled on it. Where in one issue of cacti not graphing, I see the rrd files created are having user and group as "root" instead of cacti. When I manually changed the user and group to cacti, it started graphing. However, this issue happened everytime the new RRD is created until I made the below changes.


Modified the group ownership of Boost.
Quote:
chown root:cacti boost_server.php
chown root:cacti boost_rrdupdate.php



What I thought initially is, cacti creates a rrd file where boost is used to update them on demand. But is it other-way ?

Could someone tell me the basics of how rrd is created and the role of a boost in it?

Thanks in advance.

You will want to probably use these commands. Ofcourse replace your rra directory where indicated.

chmod g+s <rra_dir>
chgrp cacti <rra_dir>

Thanks for responding.
I see it works when I change group owner ship. But i would like to know how rrd file is created. Is it through boost server?
