rmarchei / jmxsh Goto Github PK

The -T/--url_path option used to specify the path portion of the jmx service 
url is ineffective, default value of jmxrmi cannot be overridden.

This issue is due to a mismatch between the key name used for this option at 
definition time (using "url_path") and at retrieval time (using "path"). 

Patch attached.

What steps will reproduce the problem?
1. expose a command who takes an integer paramete [ ie: foo(int arg0) ]
2. call [jmx_invoke -m foo.bar:name=Bam foo -1]

What is the expected output? What do you see instead?
expected: successful update of the mbean
actual: Error: Could not find operation -1

What version of the product are you using? On what operating system?
jmxsh-R5, osx 10.7.5

Please provide any additional information below.
passing in 0 or positive values works as expected. the jmx command is an 
operation, not an attribute.

Hi,
can we get some documentation for this project?
I'm interested in finding out how to run this as a scriptable executable.
Thanks.

This project doesn't have enough document

What steps will reproduce the problem?
1. jmx_invoke -m ContentApplicationEngine:type=Cache evict


What is the expected output? What do you see instead?
There are two methods with name evict:
1)void evict(String p0)
2) void evict()

Only the first method is recognized.


What version of the product are you using? On what operating system?

Java version "1.6.0_30"
Java(TM) SE Runtime Environment (build 1.6.0_30-b12)
Java HotSpot(TM) Server VM (build 20.5-b03, mixed mode)

Linux 3.2.0-24-generic-pae #39-Ubuntu SMP Mon May 21 18:54:21 UTC 2012 i686 
i686 i386 GNU/Linux


Please provide any additional information below.

In method MBeanOperationInfo getOperationInfo(String server, String mbean, 
String opname) only the first occurrence is found.

I'm able to list mbeans in various domains and I'm able to get values of 
specific mbean attributes, but I'm unable to list all attributes of a given 
mbean.  Is this not supported or is there hidden syntax to do it?

Is it possible to connect to a JVM process without any TCP port like JConsole 
can do ?

I'm writing a Ganglia gmond python module that uses jmxsh. It was not efficient 
to constantly be writing out to a script file in order to execute commands. 
This will enable reading from standard input and returning the results of the 
commands only.

Here is the module that uses jmxsh:

What version of the product are you using? On what operating system?

Java(TM) SE Runtime Environment (build 1.6.0_27-b07)
Java HotSpot(TM) Server VM (build 20.2-b06, mixed mode)


This will work around the problem (two terminating quotes):
% jmx_get -m Catalina:type=ThreadPool,name="ajp-bio-8009"" currentThreadsBusy
4

...or this (change the order of the key/value pairs):
% jmx_get -m Catalina:name="ajp-bio-8009",type=ThreadPool currentThreadsBusy
4

Browse Mode works just fine for these mbeans.
