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

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
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

hi
i am using the same plugin its showing the output as you have given when executed directly but when i am tryingto execute it through NRPE is showing "NRPE unable to read output".
May i know how do you incorporated this plugin in your nagios.
