100 Chapter 4 Configuring Clusters
Administrator e-mail options
The ClusterCATS administration e-mail support feature reports vital statistics about
your cluster to designated e-mail accounts in your organization. You can set up the
following types of administration e-mail options:
• Report e-mail — lets you know each day how your server clusters are functioning.
Daily e-mail reports include the following information:
− Cluster name and each server’s name and IP address in the cluster
− Files — number of files in the web server’s root directory
− Disk space — amount of disk space used and remaining on the system drive that
contains the web server’s root directory
− Log files — size and location of the log files
• Support e-mail — sends an automatic e-mail nightly to Macromedia’s Technical
Support team that contains basic configuration information about your cluster. This
information enables Macromedia to provide optimal support by understanding your
environment when you call a Technical Support representative. Support e-mail
contains the following information:
− Cluster name and the number of servers the cluster contains
− Statistics for each server, including failover, redirection, and database statistics
You can also have one or more people of your choice receive copies of this
periodic e-mail.
