How to detect SIGTERM,SIGKILL signal in UNIX

Dear All

We have JBOSS server running on Linux we need to track Graceful Shutdown(SIGTERM) and Forceful Shutdown(SIGKILL) timestamp and write it into one file, I am new to UNIX Signal processing if is it possible how to detect it?

We generally do
$kill PID For Graceful Shutdown(SIGTERM)
$kill -9 PID For Forceful Shutdown(SIGKILL)

Thanks in advance.Is is possible using Shell Script or C or JAVA if yes please suggest me.

We or else someone is killing the process id of java process associated with JBOSS.
i.e we get Java process ID from `ps -ef|grep java` command output and someone is killing this PID using kill command. I have to track at what timestamp java process is killed and associated SIGNAL information i.e either SIGTERM , SIGKILL or it is for system's abnormal shutdown

Is it possible to track this information ? if yes Please help me it's an urgent.........

Regards
Mnmonu

dxshutdown(8)						      System Manager's Manual						     dxshutdown(8)

NAME
dxshutdown - Performs various types of automated system shutdown. SYNOPSIS
/usr/bin/X11/dxshutdown OPTIONS
The dxshutdown command accepts all of the standard X Toolkit command-line options, which are documented in the OPTIONS section of the X(1X) reference page. DESCRIPTION
The Shutdown Manager application, dxshutdown, provides the system administrator with a graphical user interface for running user-specified scripts at shutdown time in addition to performing the following types of automated system shutdown: Halt (and restart console mode) Reboot Single-user mode shutdown Message-only shutdown Dependencies: None. You do not need to configure anything prior to running Shutdown Manager. You must be root to run Shutdown Manager. Shutdown Manager also lets the system administrator display one or more warning messages prior to system shutdown. The dxshutdown command uses the Tru64 UNIX shutdown command as an API, passing command-line arguments as specified by application defaults and user inputs. The Shutdown Manager also provides the following features, which the shutdown command does not provide: Selection of a preshutdown script to be executed prior to system shutdown Easy cancellation for a shutdown while the timed countdown is in progress Maintenance of an error- and-script output log under /var/adm/sysman/dxshutdown.log Saving and restoring user-selected shutdown options over multiple invocations of the Shutdown Manager application For additional information about the graphical user interface, see the online help volume, which is available from the Help button in the main window of the Shutdown Manager application. To start dxshutdown from the graphical user interface: Click on the Application Manager icon on the CDE front panel. Double click on the System_Admin application group icon. Double click on the Daily Admin application group icon. Double click on the Shutdown Manager appli- cation icon. EXAMPLES
To start Shutdown Manager from the command line, enter: dxshutdown To open the Shutdown Manager help volume from the command line, enter the following command: /usr/dt/bin/dthelpview -h /usr/dt/appconfig/help/C/DXshutdown.sdl FILES
Shutdown Manager executable Shutdown Manager log file Shutdown Manager help volume Shutdown Manager resource file (for option settings) SEE ALSO
Commands: fasthalt(8), halt(8), rc0(8), reboot(8), rwalld(8), shutdown(8), sync(8), X(1X) dxshutdown(8)
