command-line - 如何仅从命令行从 jmx 界面提取 jmx 统计信息？

Question

我想提取这些数据http://code.google.com/p/memcached-session-manager/wiki/JMXStatistics通过 jmx 但仅使用命令行。

这是因为这是进入我得到的服务器的唯一途径。

任何指针都会有所帮助

提前致谢

在猛烈抨击 JMX 协议(protocol)无法通过 ssh 进行隧道传输之后，我完成了这个快速且肮脏的解决方案。
(1) 找到了一些 jmxterm 的东西，(2) 将一些简单的命令放入其中(运行 MBean 操作)(在检查了 JConsole 连接到本地 tomcat 时所做的事情之后..)和 (3) 将其格式化为可读的内容。

#!/bin/bash

# wget http://downloads.sourceforge.net/cyclops-group/jmxterm-1.0-alpha-4-uber.jar

JARFILE="jmxterm-1.0-alpha-4-uber.jar"
JMXHOST=127.0.0.1
JMXPORT=9003

function die() { echo $1 ; exit 1 ; }
function checkexe() { [ -x `which $1` ] || die "cant find executable program $1" ; }

PROGS="java grep cat sed tr xsltproc xmllint"
for P in $PROGS ; do checkexe $P ; done
[ -f $JARFILE ] || die "can't see jar file $JARFILE"

## jmxterm commands to get thread stack dump
cat >/tmp/myscript.jmx<<EOF
domain java.lang
bean java.lang:type=Threading
run dumpAllThreads 1 1 
quit
EOF

## get the stack traces
java -jar $JARFILE -l $JMXHOST:$JMXPORT -i /tmp/myscript.jmx > /tmp/allthreads.txt

grep "threadId" /tmp/allthreads.txt || die "stack trace get seemed to fail ?!"

## turn them into xml
cat /tmp/allthreads.txt | \
    sed \
        -e "s|\[ |<array>|g" -e "s| \]|</array>|g" \
        -e "s|{|<obj>|g" -e "s|}|</obj>|g" \
        -e "s|\([^ <>]*\) = \([^ <>]*\);|<\1>\2</\1>|g" \
        -e "s|\([^ ]*\) = \([^;]*\) *;|<\1>\2</\1>|g" | \
    tr '\r\n\t' ' ' | tr -s ' ' | \
    sed \
        -e "s|\([^ =]*\) = \([^;=]*\);|<\1>\2</\1>|g" \
        -e "s|\([^ ]*\) = \([^;]*\);|<\1>\2</\1>|g"\
        -e "s| *, *||g"  > /tmp/allthreads.xml

## xsl to convert xml-ified stack traces to simpler format
cat >/tmp/jmxterm_threads.xslt<<EOF

EOF

## simplify xml
xsltproc /tmp/jmxterm_threads.xslt /tmp/allthreads.xml | xmllint --format - > /tmp/allthreads_simple.xml

cat /tmp/allthreads_simple.xml
