Post result to
application server
In distributed environments, much of this processing is going on within the
mediation server. Once OpenManage Network Manager produces the polling
results, it adds them to a queue that the server then reads. In effect,
OpenManage Network Manager has posted the results to the application
server. Once the application server receives these results, it inserts them into
the database for later querying. Monitor this queue through the JMX console
> oware > service=MonitorPollingHandlerMBean.
