Oracle Database Monitoring
The Oracle Monitoring Probe constantly monitors the internal
performance and space allocation throughout the Oracle database and feeds essential
information based on pre-defined criteria to the Availability Manager for appropriate
alert notification when required. An extensive range of pre-defined alerts are
delivered with the Oracle Monitoring Probe and these can quickly be extended
to meet the needs of specific monitoring requirements.
Fig. 1 The Oracle Monitoring Probe allows you to easily define
monitoring intervals, prioritize alarms and set the level of logging detail.
Fig2. Status reports can be generated according to your specific
requirements and assistance given to correct potential problems.

to meet your changing needs and use the Hint editor to extend the DB assistance
knowledge base.
