CMON is a daemon that aggregates information from MySQL Cluster that earlier was only accessible from the cluster log or the management client, such as: * cluster state * node state * backup statistics * statistics * cluster events (cluster log basically) .. and let's you access the information using SQL, because CMON logs the information into ordinary MYISAM tables! So, it is really easy to use! In the package you also get get php scripts that you can put on your webserver to generate graphs and get a www interface to CMON. CMON can also start ndbd nodes and make decisions on how they should be started (with or without --initial). CMON starts as a daemon and will automatically create cmon database and install the necessary tables automatically.

The configuration described here is not very complicated but still needs to be done carefully. You are expected to have at least basic knowledge of: * MySQL (creating a database, granting access to users, basic SQL queries) * SMTP (what it is and what a basic SMTP dialog looks like) * POP3, IMAP (what they do and what the differences are) * basic Postfix configuration (understand the default settings in your main.cf, have read through the basic configuration document and know that your mail log file is at /var/log/mail.log) * Debian/Linux (general system administration, using a text editor, reading log files)
