display functions on weblogic admin console

hey all,

I would like to ask if it's possible to add functions manually on the weblogic
to be displayed on the web interface of the admin console. I need this for
monitoring my application. I read the documentation of weblogic about monitoring
but didn't find any manual functions that i can add, there's only the monitoring
that weblogic offers.

the functions that i would like to add eg. number of msgs recieved, or avarage
msgs ....

Thanks you in advanced
