Subject [jira] Updated: (DERBY-3500) Implement a DatabaseMBean for monitoring of a database
Date Wed, 23 Apr 2008 13:15:21 GMT

Bernt M. Johnsen updated DERBY-3500:
------------------------------------

    Attachment: DERBY-3500-v0.png
                DERBY-3500-v0.stat
                DERBY-3500-v0.diff

As a "proof of concept": A patch that implements a DatabasMBean interface with an BasicDatabaseMBeanImpl
implementation. Implements number of locked objects (in the sense of rows and tables) and
transactions per second. Attached is also a JConsole screen shot. The patch needs more work
(e.g comments ;-) and security stuff, but comments are very welcome.
