  1. Service Integration Bus Performance Tool A simple performance monitoring tool (using PMI) for WebSphere SIBus Messaging and/or WebSphere Business Events Author - David Granshaw

  2. Main Objective To provide developers, testers, PoCs and customers with a simple way to understand how their applications are executing and performing. Note it is an alphaworks tool, not an official IBM product

  3. The tool uses PMI Statistics • What are PMI (performance monitoring infrastructure) statistics? • PMI are effectively statistics added by developers to provide runtime information about performance • The statistics conform to a set of standard rules so they can be accessed using the WAS console or via a standalone client (i.e. this tool) • Why not just use the WAS Console to view PMI stats? • You can but the idea of this tool is to automatically select, enable and present the relevant PMI statistics to make it simple to understand how your SIBus or WebSphere Business Events is performing • The presentation of data the PMI data is tailored to a WAS SIBus or WebSphere Business Events user. • Statistics are updated every few seconds • It is simple to select or deselect additional statistics.

  4. Examples of Performance Data – SIBus MessagingThese are just examples of the many statistics For WebSphere SIBus Messaging: • Current message production and consumption rate for every queue and topic on the system (including temporary queues) • Message production and consumption rates broken down by reliability level for each queue and topic • Current number of producers/publishers and consumers/subscribers attached to each queue/topic • Number of messages, using the Best Effort reliability level, that have been discarded • Numbers of threads in each thread pool (for example: MDBs, ORB, Web container) • Number of bytes written and received by the application servers, message engines, and MQ links • Heap size and current percentage of free heap.

  5. Examples of Performance Data – WebSphere Business EventsThese are just examples of the many statistics For WebSphere Business Events: • Number and type of events arriving and the rate of arrival • Number and type of actions being generated and the rate of generation • The number of rules being processed and the rate of processing • A complete list of all event types, action types and business event rules currently deployed on the WebSphere Business Events server • The ability to view the durability and persistence of events and actions • A view of the CPU and java heap that WebSphere Business Events is currently consuming.

  6. Using the PMI Tool • Run the start up script and select the server or dmgr to connect to: • That is all you need to do. • The tool will determine whether SIBus and/or Business Events is installed • The stats for the chosen server will then be enabled and automatically displayed. The WAS soap port is generally: 8880 for a single server 8879 for a dmgr

  7. General Stats Page Click on the left hand tree to select the PMI stats of interest 38% of the java heap is currently being used. This WAS process is using 17% of the system CPU.

  8. SIBus example : Topics Topics currently defined in SIBus The server is publishing and consuming non persistent messages 9209 messages were published to this topic (current arrival rate is 100 evts/s) 929 actions were published to this topic (current rate 10 actions/s) There are no incomplete publications i.e. messages are being processed fast enough to avoid build up

  9. WebSphere Business Events example : Events and Actions WBE Events : Number of events received and event arrival rate 50,414 events (PerfEvent1Rule) have arrived. These events are currently arriving at a rate of 100 events/s. WBE Actions : Number actions generated and rate of generation 7,320 actions (OptionAction)have been generated. They are currently being generated at 10 events/s.

  10. Additional examples: WBE Interaction Sets 1 interaction set is being used. The interaction set has been evaluated 13,213 times (current rate of evaluation is 100 events/s). WAS Thread pool data

  11. Examples of other stats immediately available… SIBus • Queue message stats • Communications stats • Number of bytes read/written to/from JMS clients or other messaging engines • Number of client or messaging engines connected • Number of communication errors • WMQ link stats • Number and size of messages sent/received • Data store stats • JCA Connection Pool stats - Current, mean and low/high water connections for JCA • WebSphere Business Events • Fetchers - Count of JDBC and JRules Fetchers. • Object Grid Queue depth (for WBE Object Grid partitions and WXS queues) • Steps cache usage (number of Steps cache hits) • Delayed event/action data - difference between actual and expected execution times • Rule processors data (number of rule processors currently being used)

  12. Additional stats can be easily enabled This shows the additional stats that can be enabled on SIBus topics. Checking and unchecking the boxes will enable or remove PMI stats.

  13. WBE Clusters The tool will work with clusters. The tool connects to the dmgr on port 8879 and will display a list of all the available servers. Simply click on the server name to enable all the WBE centric PMI performance statistics for that server. The tool will only connect to one server at a time but multiple instances of the tool can be used to view different servers simultaneously.
