jvmtop's Issues
Resolve symlinks to shell wrapper location
The first line of code in the shell wrapper should read:
DIR="$(cd "$(dirname "$(readlink -f "$0")")" && pwd)"
to support symlinking to that script. Else jvmtop won't find its JAR.

jvmtop sees only itself running in AIX
What steps will reproduce the problem?
1. Running jvmtop on AIX with WebSphere JVMs
2.
3.
What is the expected output? What do you see instead?
Seeing all running JVMs
What version of jvmtop are you using? On what operating system?
The latest (just downloaded)
Please post the output of the following commands:
java -version
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2)
Classic VM (build 1.4.2, J2RE 1.4.2 IBM AIX build ca142-20090307 (SR13) (JIT
enabled: jitc))
echo $JAVA_HOME (for unix/linux systems)
twausxwasapp57:/home/i262666 >echo $JAVA_HOME
/usr/java6
echo %JAVA_HOME% (for windows)
Please provide any additional information below.
When running jvmtop it sees only itself running. Most likely because the the
security because the JVMs are run under the "wasadmin" account by the WAS
administration.
However, when I run the following command
ps -elf | grep java
all JVMs are displayed.
Appreciated your help

Does not work - possible solution.
jvmtop does not work for me (ERROR: Could not attach to process). Running
64-bit ubuntu 13.04.
I also noticed that jstack does not work but running jstack like this works:
jstack -J-d64 -m <pid>
Maybe this can be used in jvmtop to fix the issue?

A --help argument would help
What steps will reproduce the problem?
1. ./jvmtop.sh --help
jvmtop has several arguments that can only be learned through looking at a few
different pages in the wiki - since there is no source code, hard to know if
they are all documented anywhere.
What is the expected output? What do you see instead?
[me@localhost~]$ jvmtop --help
JvmTop 0.7.1 alpha, http://code.google.com/p/jvmtop
Usage: info [OPTIONS]... [PID]
Monitor JVM metrics on the command line
Options (only one can be specified):
--help this text
--once [PID] Run jvmtop one time, then exit
--delay N Delay N seconds between updates
--profile PID Profile a specifc JVM instance
Examples:
jvmtop Summarize all currently running JVM's
jvmtop 3944 Display detailed information for a single JVM (pid #3944)
jvmtop --delay 3 --profile 3944
Profile process #3944, updating the display every 3 seconds
Plus appending what you currently have written up for the column definitions on
the ExampleOutput wiki page would be a nice touch.
or for an unknown argument:
[me@localhost~]$ jvmtop --foo
jvmtop: unrecognized option '--foo'
Try --help for more information.
Actual:
[me@localhost~]$ jvmtop --help

An option to display threads in their thread groups would be awesome
Enhancement.
It would be awesome to be able to organize the details view in a hierarchy /
tree which would group threads under their parents. htop is an example of do
this for processes. Personally, I have never found that of much use, but I see
a lot of application for this type of output for JVM threads.
Pitfalls I see are that searching the thread group tree repetitively might be
too cpu / time consuming and there is no guarantee that thread groups all have
unique names, so things might get a bit tricky.
An interim step might be to simply display all threads rather than the top 10.

Connecting to a PID with -p or --pid does not work
Using JvmTop 0.8.0 alpha.
According to the help -p or --pid must be used to connect to a PID, but instead
-p or --pid must not be specified to connect to a PID.
When connecting to a PID, do not specify -p or --pid:
./jvmtop.sh 2384
instead of:
./jvmtop.sh -p 2384
or
./jvmtop.sh --pid 2384
Cheers, Ian.

Enhancement.
What steps will reproduce?
1. jvmtop.sh --once <pid>
What is the expected output? What do you see instead?
When running a monitoring program like top once, the screen doesn't clear
before displaying output, the results simply appends to existing location in
the window. This allows me to see, for example, the results of --once twice in
the same window.

Unable to attach to other user`s JVMs, even if root
What steps will reproduce the problem?
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1. start a JVM with user X
2. try to run jvmtop from another user, or root, it will not attach.
3. with JConsole I can attach to all JVMs when JConsole starts as root.
What is the expected output? What do you see instead?
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
More of a nice to have really. I have close to 10 JVMs running on a system,
all owned by different users, and it would be nice if I could monitor all of
them from a single instance of jvmtop.
What version of the product are you using? On what operating system?
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
jvmtop 0.4.1
Mint 14, native install and inside VirtualBox, same results.
all JVMs use:
java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b11)
Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)

Keep up the great work, I love this tool.

hi,
Like i had discussed about my intention to develop a nagios plugin by using
jvmtop.sh, i completed the script. On testing. I get to see a shocking result
about the thread creations in my linux centos box. I set nagios to check and
run script every 2 min. but when i looked at the performance in HTOP. i see the
thread is continuously growing by .jvmtop.sh. I started on Friday. and today on
monday it almost created a min 2000 thread!!. consuming 300MB resident memory,
and all having priority 15.
With this much thread creation by jvmtop, i dont think nagios plugin will work
on top of it. below is the line which executes the jvmtop.sh and grep the jvm
process. eg: script.sh -j org.jboss.Main
tmp_output=$(/usr/local/nagios/libexec/jvmtop.sh --once | grep $PROCESS)
Let me know whats your openion on this.

please provide source code downloadable file
Please provide a downloadable file for the source code, other than using the
standard download link from the source tab in the the google code source
browser. This is going to be more downstream friendly to provide to other
operating systems.
Right now I can only do it this way:
http://jvmtop.googlecode.com/archive/a3904b5b7e3adc5244e8658f8c54ef849e3ca56e.zi
p
However there is no way to track this in being changed. However, if you had a
downloadable link named, for example: jvmtop-src-0.8.0.tar.gz or
jvmtop-src-0.8.0.zip, this can be tracked quiet easily.
Thanks so much!

jvmtop detail mode output should group related info
Enhancement.
For example:
- GC info is split on 2 lines
- uptime and %CPU are on different lines
- pid & user are far apart
- system time & JVM up time are displayed differently
- a mix of formats in the header makes parsing with awk or perl harder than needed
Probably first on my list would be to reorganize the output to make it more
top-like and to ensure that things that are related to each other are near each
other.
One possible suggestion for a reorg:

ant dist fails because dist directory is not created
I just cloned the git repo and executed ant dist, which fails with the message:
/home/foo/tmp/jvmtop-git/jvmtop/jvmtop/build.xml:42: Problem creating jar:
/home/foo/tmp/jvmtop-git/jvmtop/jvmtop/dist/jvmtop.jar (No such file or
directory) (and the archive is probably corrupt but I could not delete it)
The problem is that the jvmtop/dist directory doesn't exist. The bit about the
corrupt archive is spurious.
Here's a patch to create the directory. After this change, I find that ant dist
runs to completion successfully.

while you're at it, how about including the date/time like top does. this would
be especially useful when running as a background task.

Doesn't work on OS X
What steps will reproduce the problem?
1. Try and run with OS X
2. Does not work. Says requires real JDK.
tools.jar is not packaged up as a separate jar in the OS X JDK. You don't need
to add it to the classpath like on Windows/Unix. I wrote and tested the
following fix:
if [ `uname` != 'Darwin' ] ; then
if [ ! -f "$TOOLSJAR" ] ; then
echo "$JAVA_HOME seems to be no JDK!" >&2
exit 1

Would it be possible to add an option to suppress the cut of the thread list
("Note: Only top 10 threads (according cpu load) are shown!") in the detail
mode?

An arugment along with --once to filter exact JVM Process name to query.
hi,
In order to Minimize CPU time and CPU % taken by jvmtop.sh to find and display
all the JVM found, can we have an argument like
./jvmtop.sh --once <jvm name>
eg:
./jvmtop.sh --once org.jboss.Main
OUTPUT:-
JvmTop 0.7.1 alpha - 06:13:38, amd64, 4 cpus, Linux 2.6.18-19, load avg 0.00
http://code.google.com/p/jvmtop

11228 org.jboss.Main 549m 3993m 70m 304m 0.00% 0.00% S6U25 compiere 74
This would limit what jvmtop search and query for. making less CPU usage and
intensive.
