## Monitoring the ORB

ORB statistics are disabled by default. To gather ORB statistics, enable monitoring with this `asadmin` command:

    set serverInstance.iiop-service.orb.system.monitoringEnabled=true
    reconfig serverInstance

### Connection Statistics

The following statistics are gathered on ORB connections:

- `total-inbound-connections` Total inbound connections to ORB.

- `total-outbound-connections` Total outbound connections from ORB.

Use this command to get ORB connection statistics:

    asadmin get --monitor
        serverInstance.iiop-service.orb.system.orb-connection.*

### Thread Pools

The following statistics are gathered on ORB thread pools:

- `thread-pool-size` Number of threads in ORB thread pool.

- `waiting-thread-count` Number of thread pool threads waiting for work to arrive.

Use this command to get ORB thread pool statistics:

    asadmin get --monitor
        serverInstance.iiop-service.orb.system.orb-thread-pool.*
