using jboss objects


Hi all

I need to make a script that controls or checks certain assets of a JBoss server. Like if the server is running or down, or how much memory he uses, etc.
Now, via the website of Nagios, i've found a script which i can use

Code:
# ./check_mbean_collector -H host -p 5566 -m jboss.system:type=ServerInfo -a ActiveThreadCount -w 200 -c 400
JMX attribute ActiveThreadCount has value 63|jboss.system:type=ServerInfo:ActiveThreadCount=63
So this is an example of it working, but now i want to check the used memory and when the free memory gets below a certain value, i need to get a CRIT...
Where can i find the things i need to check on this?
On the JBoss server i get an overview of everything, but i really don't have a clue where to start looking...

Can someone help me with this ^^?

thanks in advance

UPDATE

okay, i've found it
Code:
# ./check_mbean_collector -H host -p 5566 -m jboss.system:type=ServerInfo -a FreeMemory -w 460280464 -c 500000000
JMX attribute FreeMemory has value 404803920|jboss.system:type=ServerInfo:FreeMemory=404803920
so i geuss the memory is in bytes?
but that doesn't matter, so when i run this i get the result as you see above
when i run this through Centreon/Nagios i get an Ok or CRIT or whatever when the value gets above a certain value.
So actually i get a WARNING when the free memory gets ABOVE a certain value (that doesn't make sense.. because i need to know when it gets BELOW a certain value...)
how can i manage this?

Thanks
