ahhh, i got it. here is the complete script if someone want to use it under windows servers (script is originaly from w.leibzon!):

| # ============================== SUMMARY =====================================
| #
| # Program : check_jboss.pl
| # Version : 0.31
| # Date : May 16, 2007
| # Author : William Leibzon - william at leibzon.org
| # Summary : This is a nagios plugin to check jboss parameters by means
| # of twindle utility on the same host

| #
| # ============================= SETUP NOTES ==================================
| #
| # This is a nagios plugin to check JBOSS server attributes. It requires
| # local JBOSS provided twiddle utility to be available and will call it
| # (and consequently JAVA process) to actually connect to JBOSS server.
| # Therefore keep in mind that this plugin requires rather heavy processing
| # and you're lot better off doing this through NRPE.
| #
| # For setup make sure to adjust path to twiddle which is rather non-standard
| # in this plugin by default (/opt/jboss/bin/twiddle) and make sure you have
| # either utils.pm in the directory specified with "use lib" or comment it out
| # uncomment 'my %ERRORS' and 'my $TIMEOUT'.
| #
| # The attributes are data attributes of JBOSS bean which you must
| # specify with '-J'; specifying type with '-T' is also required by
| # twiddle, please see documentation for JBOSS and twiddle.
| #
| # For each attribute you specify in '-a' you must also specify warning
| # and critical values in the same order in '-w' and '-c' (see below)
| # Using '-f' would cause all attribute values to also be available
| # for Nagios performance processing and with '-A' you can specify
| # list of that attributes even if they are not otherwise listed in
| # '-a' (you can also do '-A *' to just get all the atributes).
| #
| # Warning and critical levels are specified with '-w' and '-c' and each
| # one must have exact same number of values (separated by ',') as number
| # of attribute names specified with '-a'. Any values you dont want
| # to compare you specify as ~ (or just not specify a value, i.e. ',,').
| # There are also number of other one-letter modifiers that can be used
| # before actual data value to direct how data is to be checked.
| # These are as follows:
| # > : issue alert if data is above this value (default for numeric value)
| # < : issue alert if data is below this value (must be followed by number)
| # = : issue alert if data is equal to this value (default for non-numeric)
| # ! : issue alert if data is NOT equal to this value
| # A special modifier '^' can also be used to disable checking that warn
| # values are less then (or greater then) critical values (it is rarely
| # needed). A quick example of specialized use is '--warn=^<100 --crit=>200'
| # which will cause warning alert if value is < 100 and critical alert
| # if its greater then 200.
| #
| # =================================== TODO ===================================
| #
| # 1. [0.3 DONE] Update to my latest format & code for parsing warning & critical
| # parameters so they can be of the form "<value", ">value" as well
| # as "~". Note that in this version the "<value" is specified as
| # "-value" as with check_jboss plugin - but this will be going away!
| # 2. Add support for storing values in some file so as to allow to check
| # on rate of change rather then just actual value
| # 3. As an option instead of using "twiddle" the data is retrieved
| # from JBoss HTTP status/config data.
| # 4. Add full "help" output in the "check_help" function
| # 5. [0.2 DONE] Need to change how twiddle its called so that pid of the remote
| # 6. [0.31 DONE] Added -S parameter to specify JMX service instead of type
| # shell is kept and that process can be killed during timeout (otherise
| # it maybe left hanging and become a zombie).
