TPTP trace.trcxml notation format new agent controller 4.3 [message #91028]

Hi,
I want to play around with the trace.trcxml and use/parse some stuff out
of it and link it to other data. However I am a bit puzzled about the time
notation format.

In the first part of the trace file:
<?xml version="1.0"?>
<TRACE>
<node nodeId="" hostname="localhost" ipaddress="127.0.0.1" timezone="-60"
time="1168431557.827301979"/>
<processCreate processId="78b7eb83-a20f-4a87-bf6d-9a418e6426fc"
pid="22985" nodeIdRef="" time="1168431557.827301979"/>
<agentCreate agentId="045b7246-0493-46a7-9ef4-0663db784a06"
version="2.000" processIdRef="78b7eb83-a20f-4a87-bf6d-9a418e6426fc"
agentName="org.eclipse.tptp.jvmti" agentType="Profiler"
agentParameters="server=standalone" time="1168431557.827301979"/>
<traceStart traceId="409267cd-dfad-4c3e-8a1a-8c038ba0f4a7"
agentIdRef="045b7246-0493-46a7-9ef4-0663db784a06"
time="1168431557.827538013"/>

There are clearly some "unix" time stamps, which can be therefore be
linked to other files generated on the same machine with similar
timestamps. But now at the point where it is going to track objects it
suddenly prints:

<threadStart threadId="1" time="19615175628.096279144"
threadName="Reference Handler" groupName="system" parentName=""/>
<threadStart threadId="2" time="19615175628.096366882"
threadName="Finalizer" groupName="system" parentName=""/>

Which are timestamps at the end of the 32bit lifetime in 2038.... they are
not very useful. Is this a unwanted "feature" or am I missing out on
something?

Help would be appreciated.

Best regards,
Bertrand

Hi Bertrand,

Which operating system and processor architecture are you using?

In general, the timestamps are indeed an OS timestamps (Unix in your
case). If you are using Linux on IA-32, the timestamp issues you see are
probably related to the following bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=165190

If this is the case, you may want to check the latest binaries
(currently under development for TPTP 4.4) in the following link:
http://www.eclipse.org/downloads/download.php?file=/tptp/4.4 .0/dev/TPTP-4.4.0-200701080100/javaprofiler.linux_ia32-TPTP- 4.4.0-200701080100.zip

I believe the problem was addressed in this build.

HTH,
Asaf

Hi Asaf,

Thanks, this was indeed the problem. I have one other question in the
format of the trcxml file, the size="80" element, is this in bits or in
bytes?

I am producing some nice graphs now how memory usage evolves over time,
using some scripts pulling out data and feeding it to gnuplot. If anyone
is interested I can offcourse post them once they are more or less usable.
However no nice workbench integration or something.....

Best regards,
Bertrand

The "size" attribute in in bytes.

See
http://www.eclipse.org/tptp/platform/documents/resources/pro filingspec/XML4Profiling.htm
for more details on the format of the Event Specification for Java Profiling
(AKA trace.trcxml).
