The HPROF Profiler

Appendix D Remote Servlet Profiling 115

The syntax of HPROF is as follows:

-Xrunhprof[:help]|[:option=value,option2=value2, ...]

Using help lists options that can be passed to HPROF. The output is as follows:

Hprof usage: -Xrunhprof[:help]|[:<option>=<value>, ...]

Option Name and Value Description Default

--------------------- ----------- -------

heap=dump|sites|all heap profiling all

cpu=samples|old CPU usage off

format=a|b ascii or binary output a

file=<file> write data to file java.hprof

(.txt for ascii)

net=<host>:<port> send data over a socket write to file

depth=<size> stack trace depth 4

cutoff=<value> output cutoff point 0.0001

lineno=y|n line number in traces? y

thread=y|n thread in traces? n

doe=y|n dump on exit? y

You must also change a line in the iPlanet Web Server start script. The start

script file is server_root

/https-server_id/start. Change the following line:

PRODUCT_BIN=uxwdog

to this:

PRODUCT_BIN=ns-httpd

Start the server by running the start script. Since the server runs in the

foreground (the change in step 2), the command prompt returns only after the

server has been stopped.

4. In another window or terminal, find the process ID of the server process.

% ps -ef | grep ns-httpd

This command lists two ns-httpd processes. Look at the PPID (parent process

ID) column and identify which of the two processes is the parent process and

which is the child process. Note the PID (process ID) of the child process ID.

5. Send a SIGQUIT signal (signal 3) to the child process:

% kill -QUIT child_PID

1 2 ... 110 111 112 113 114 115 116 117 118 119 120 ... 123 124
