profiling - Fail to profile remote java app using TPTP -

-

i trying profile cpu usage using tptp. application profile run on linux rh as5. installed , configured agent controller described here

i ran java application using command

java '-agentlib:jpibootloader=jpiagent:server=standalone,file=log.trcxml;cgprof' myapp

the monitoring station all-in-one tptp version 4.6.2. followed stepes described here

on eclipse - on "profile configuration" choose new configuration "attach agent", set host remote linux machine myapp running, test connection succeed , when "agents" tab, see "pending...", background process "feching children host" running , can't find makes impossible profile.

any idea?

java '-agentlib:jpibootloader=jpiagent:server=enabled;cgprof' myapp

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
