Dear all,
within the last week I have been working on X2Go Session Broker a bit
more, pushing it towards release 0.0.3.0.
One feature, that was still missing, was a means to perform load
checks on associated load-balanced X2Go servers, so that a real "load"
balancing could take place.
Until last week, server load was detected by only counting the number
of running / suspended X2Go sessions. If you have users that are
working hard on an X2Go server, then the number of sessions is a very
inaccurate way of detecting server load.
So now, we count X2Go sessions plus detect a couple of server metrics
(via a background daemon, aka x2gobroker-loadchecker). All gathered
information will be combined into a load-factor. The load-factor and
the number of running/suspended sessions, will decide on what host the
next new X2Go session will be started.
Quick install for testing the new feature (from the nightly builds, of couse):
Debian:
apt-get install x2gobroker # will update your x2gobroker packages apt-get install x2gobroker-loadchecker
-> make sure x2gobroker-loadchecker starts via your init system
edit /etc/x2go/x2gobroker.conf, set use-load-checker for inifile
broker backend
-> make sure, you have at least one session profile setup in
/etc/x2go/broker/x2gobroker-sessionprofiles.conf that uses more than
one host
-> make sure, that you use "broker-agent-query-mode = SSH" for this
session profile.
-> for the fully-featured show, enable X2GOBROKER_DEBUG in
/etc/x2go/broker/defaults.conf
Now watch /var/log/x2gobroker/loadchecker.log and
/var/log/x2gobroker/broker.log for system load information.
I'd be happy to receive some test results within the next couple of
days/2-weeks. The 0.0.3.0 release is heavily overdue and I would like
to finalize this version by the beginning of April.
Thanks+Greets, Mike
