Application DIMON is a web based interface application with access to all information about the monitored databases and its configuration parameters. It can be also used to for communication between the administrator and the customer. During the evaluation of incoming message from the database the system automatically recognizes the seriousness of the situation. In critical cases it immediately sends an alert to the responsible database administrator. The majority of incoming information and generated messages are stored in the central monitoring system.

The information is also used for historical database performance overview or it can be used for example to view the growth of tablespaces. All the gathered information are available to the administrators or to customers using the DIMON application. Information from the monitored databases are sent in XML format which ensures easy expandability with additional modules. Other modules can also monitor the application or different parts of application. Sending information via email is performed on regular basis.

System response time to gather information about monitored database is tens of seconds maximaly up to one minute. After the email is received by the monitoring system the state of the database is eveluated immediately.
