web application instrumenting JBoss 7 to provide resource metrics to JBison

1. Deploy the war file (copy into JBOSS_HOME/standalone/deployments)

2. Start JBoss

3. Navigate to http://127.0.0.1:8080/buffalo/rest/datasource/ExampleDS to gather metrics for the ExampleDS data source

4. Deploy another data source (via mysql-ds.xml) and navigate to http://127.0.0.1:8080/buffalo/rest/datasource/TestDS/mysql-ds.xml

5. Create a JSON monitor in JBison (https://jbison.com) to monitor the metrics exposed by buffalo

More details on my blog http://kijanowski.blogspot.com/2013/02/collecting-monitoring-and-charting.html

It is possible to collect one particular metric of all data sources, for example the number of available connections in the pool: http://127.0.0.1:8080/buffalo/rest/datasources/pool/AvailableCount Available parameters are:

• ActiveCount
• AvailableCount
• AverageBlockingTime
• AverageCreationTime
• CreatedCount
• DestroyedCount
• MaxCreationTime
• MaxUsedCount
• MaxWaitTime
• TimedOut
• TotalBlockingTime
• TotalCreationTime

Or the number of Prepared Statement Cache Access: http://127.0.0.1:8080/buffalo/rest/datasources/jdbc/PreparedStatementCacheAccessCount Available parameters are:

• PreparedStatementCacheAccessCount
• PreparedStatementCacheAddCount
• PreparedStatementCacheCurrentSize
• PreparedStatementCacheDeleteCount
• PreparedStatementCacheHitCount
• PreparedStatementCacheMissCount

The JVM memory stats are available at: http://127.0.0.1:8080/buffalo/rest/jvm/memory/heap-memory-usage http://127.0.0.1:8080/buffalo/rest/jvm/memory/non-heap-memory-usage

The JVM memory pool stats are available at: http://127.0.0.1:8080/buffalo/rest/jvm/memory-pool/{name}/{type}

where {name} is:

• Par_Eden_Space
• CMS_Old_Gen
• Par_Survivor_Space
• CMS_Perm_Gen
• Code_Cache

where {type} is:

• collection-usage-threshold
• collection-usage-threshold-count
• usage
• peak-usage
• collection-usage

The Thread usage metrics are available at: http://127.0.0.1:8080/buffalo/rest/jvm/threading

The http/https connector metrics are available at: http://127.0.0.1:8080/buffalo/rest/connector/http http://127.0.0.1:8080/buffalo/rest/connector/https

The JMS metrics are available at: http://127.0.0.1:8080/buffalo/rest/messaging/default/jms-queue/testQueue http://127.0.0.1:8080/buffalo/rest/messaging/default/jms-topic/testTopic
