[Xymon] jboss monitorin

[Marco Avvisano]

Hi Andy,
we use jboss 4.3.2 / 5.0.1, and xymon client.
For Runtime bean the problem was "not registred" values, until the first 
access from jmxconsole.
I solved  adding the command

curl 'http://myserver:myport/jmx-console/HtmlAdaptor?action=inspectMBean&name=java.lang%3Atype%3DRuntime' > /dev/null

in jmxstat.sh.
Probabily i have the same problem for the column GCInfo, collect on the 
version 5.0.1 but not on 4.3.2

I use the shell script for xymon, and the environment seem to be correct.
I get this error

JMX seems to report memory in kb (jboss 4,2.3). So, if i consider the 
conversion in the tcl in mb, and on the graph in gb, i get correct 
values (es . max heap size).
Found this link about (for 1.5.0) :
http://docs.oracle.com/javase/1.5.0/docs/guide/management/jconsole.html#summary


On the version 4.2.3 i need to add a new section for ThreadPool ( 
jboss.web:typeThreadPoll,name=http-myipserver-myports). Not always find 
the way to make graph :- (the value and the color status are "attached" )
