DB2 Performance Monitoring: Tools & Methods

In DB2, there are multiple methods available for monitoring database performance.

1. Utilize DB2’s built-in monitoring tools: DB2 comes with various monitoring tools such as db2top and db2pd, which can be used to monitor database performance metrics like CPU usage, memory usage, and disk IO.
2. Monitor SQL statements: By executing certain monitoring SQL statements, performance metrics of the database can be retrieved, such as buffer pool hit rate, locking situation, and SQL execution time.
3. Utilize third-party monitoring tools: In addition to the built-in monitoring tool of DB2, you can also use some third-party monitoring tools to keep track of database performance, such as IBM Data Server Manager and BMC Performance Manager.
4. Set up alerts and event monitoring: you can establish alert rules so that when the database performance reaches a certain threshold, an alert is triggered and can be promptly addressed.

In general, by utilizing the above methods, you can comprehensively monitor the performance of the database, promptly identify and address any potential performance issues, and ensure the stable operation of the database.
