How to retrieve connection statistics for a resource adapter in EAP 6

Solution Verified - Updated -

Environment

  • Red Hat JBoss Enterprise Application Platform (EAP)
    • 6.x

Issue

  • How can the "Active", "In-Use" and "Available" connections for a resource adapter be monitored?

  • I am trying to get the statistics in domain mode using the below example -

/deployment=ra16outij.rar/subsystem=resource-adapters/statistics=statistics/connection-definitions=java\:\/testMe:read-resource(include-runtime=true)

but when I am using tab to run command as above cli doesnt recognising "subsystem"

[domain@X.X.X.X:9999 /] /deployment=wmq.jmsra.rar/[not able to go further]

Resolution

  • For a simple resource adapter (testRar.rar) with a connection factory bound in JNDI as java:/eis/ABCConnectionFactory the following CLI commands return connection statistics:
[disconnected /] connect
[standalone@localhost:9999 /] /deployment=testRar.rar/subsystem=resource-adapters/statistics=statistics/connection-definitions=java\:\/eis\/ABCConnectionFactory:read-resource(include-runtime=true)
{
    "outcome" => "success",
    "result" => {
        "ActiveCount" => "1",
        "AvailableCount" => "20",
        "AverageBlockingTime" => "0",
        "AverageCreationTime" => "0",
        "CreatedCount" => "1",
        "DestroyedCount" => "0",
        "InUseCount" => "0",
        "MaxCreationTime" => "0",
        "MaxUsedCount" => "1",
        "MaxWaitCount" => "0",
        "MaxWaitTime" => "0",
        "TimedOut" => "0",
        "TotalBlockingTime" => "0",
        "TotalCreationTime" => "0"
    }
}
  • For domain mode CLI command will be :
[domain@localhost:9999 /] /host=<HOST_NAME>/server=<SERVER_NAME>/deployment=testRar.rar/subsystem=resource-adapters/statistics=statistics/connection-definitions=java\:\/eis\/ABCConnectionFactory:read-resource(include-runtime=true)

NOTE - From EAP 6.3.x onwards, resource adapter's statistics are disabled by default. Hence you need to enable it using CLI command :

[domain@localhost:9999 /] /host=<HOST_NAME>/server=<SERVER_NAME>/deployment=testRar.rar/subsystem=resource-adapters/statistics=statistics/connection-definitions=java\:\/eis\/ABCConnectionFactory:write-attribute(name=statistics-enabled,value=true)
  • It is not possible to obtain statistics if the resource adapter is deployed as a module and not as a deployment (i.e in deploy directory).
