Improved management ------------------- Key: JBAS-1436 URL: http://jira.jboss.com/jira/browse/JBAS-1436 Project: JBoss Application Server Issue Type: Task Security Level: Public(Everyone can see) Components: JCA service Reporter: Adrian Brock Assigned To: Vicky Kak Priority: Minor Fix For: JBossAS-4.2.3.GA, JBossAS-5.1.0.CR1 Forum Discussion Thread: http://www.jboss.org/index.html?module=bb&op=viewtopic&t=48682 **This is a holder issue. Each section should be raised as a new issue as it is developed with a link from this issue.** There are a number of areas in JCA that need better management capabilities. Some of these stats may also reveal the need for new configuration/tuning parameters. In core JCA: 1) Better visibility on the ManagedConnectionFactory. This is currently a DynamicMBean that provides basic config parameters, but we could also provide a proxy/wrapper to provide statistics of operations on the factory and its ManagedConnections. a) createManagedConnections b) matchManagedConnections c) events on from the listeners 2) Better visibility of the Pool(s) Only top level statistics are provided (you cannot see the subpools). The statistics are also not synchronized with the pool (for performance reasons and also the fact that each stat is retrieved on individual MBean getAttribute requests) Additional statistics could include wait times when requests are waiting on an empty pool, idle time of unused connections, etc. 3) Better visibility of the ConnectionManager Currently this has no visibility for management. Its main responsibilties are transactions enlistment and security. e.g. This could show how long is wasted because <track-connection-by-tx/> does not return the connection the pool until transaction completion. 4) JDBC resource adapter PreparedStatementCache stats Query time stats etc. 5) JMS resource adapter Message send/receive stats 6) Inbound messaging Stats for message delivery 7) Transaction inflow Stats for transaction inflow and also display a list of current inbound transactions 8) Work management Stats for the work management pools and timers
