Database Monitoring

The most important functions that you require for performance monitoring of the database include the following:

->Overview of the database buffers' status

->Overview of the currently running database operations, particularly the SQL statements

->Statistics on the executed SQL statements and their costs

->Overview of the distribution of read and write accesses at the logical (tablespaces) and physical level (for example, container for DB2 for Linux, UNIX, and Windows or datafiles for Oracle) and thus about the hard drives

->Overview of the current lock situations

->Overview of whether the database indexes and optimizer statistics are up to date

->Access to the database's error log and logging of parameter changes
