web application instrumenting JBoss 7 to provide resource metrics to JBison
-
Deploy the war file (copy into JBOSS_HOME/standalone/deployments)
-
Start JBoss
-
Navigate to http://127.0.0.1:8080/buffalo/rest/datasource/ExampleDS to gather metrics for the ExampleDS data source
-
Deploy another data source (via mysql-ds.xml) and navigate to http://127.0.0.1:8080/buffalo/rest/datasource/TestDS/mysql-ds.xml
-
Create a JSON monitor in JBison (https://jbison.com) to monitor the metrics exposed by buffalo

- 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 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

where {type} is:
- collection-usage-threshold
- collection-usage-threshold-count
