Martin, I believe someone else has pointed out that submissions have been closed (and apparently for a very long time...). I found most of the scripts there not quite right for what I wanted to do, so I wrote my own. I have put them up at http://cryptio.net/~ben/ganglia/ for your cunsumption. They include * disk - measures disk IO (per disk as well as cumulative) * network - reports per-interface stats (which I combined in a ganglia report to show all on one graph - fantastic for frontend/backend stuff) * mysql - reports queries per second as well as broken slow queries * sensors - CPU temp. et al for Tyan motherboards (may work for others) There is also a crontab file there for /etc/cron.d/ that calls them every two minutes and includes the (with this list's help) fixed num-users metric: */2 * * * * root /usr/bin/gmetric --name="users" --value=`who | wc -l` --type=int16 One thing I like about these scripts is that they do a fair bit of error checking, so if something happens that might cause them to fail every two minutes, you don't get 100 messages in your inbox the next morning. For example, if mysqld dies on an unimportant box, you don't want to be inundated with messages. HTH, -ben p.s. these scripts have been written for a redhat-based linux installation (Fedora, CentOS, etc.). I don't know how portable they are. I expect not very much. :) -- Ben Hartshorne email: [EMAIL PROTECTED] http://ben.hartshorne.net
