TPTP profile files too large [message #257828]

I'm using TPTP 4.4.1 and Eclipse 3.3.2 to profile a JBOSS application. The
application is running on Windows Server 2003 with Java 1.5.0_11. I'm
using the Agent Controller in standalone mode on the server. After just a
few minutes, the profile file that is generated is typically more than 500
MB in size. Eclipse tends to crash when importing these files. I want to
profile applications for much longer time periods, so this file size is
not going to be usable.

I am using a profile file and a filter file. I can verify that the classes
I exclude in the filter file do not appear in the trace file, and the
settings in the profile file appear to be working. I have tried various
combinations of profile settings, but unless I turn tracing off altogether
the trace files are unmanageably large.

Here is an example of a profile file that I have been using:

MONITOR_MODE = none
FILTERS = true
TRACK_GC_EVENT_TYPES = none
ID_STYLE = static
OPTIONS = true
TIMESTAMPS = true
METHOD_COUNTS = false
OBJ_ALLOC_IS_ARRAY = false
STACK_INFORMATION = normal
BOUNDARY_DEPTH = 1
TICKET = false
TRACE_MODE = full
TRACE_IDREFS = false

I keep adding classes to the exclusion list in the filter file, but the
file size continues to be too large. Here is an example of a filter file I
have used:

java* * EXCLUDE
sun* * EXCLUDE
sun.misc.* * EXCLUDE
com.sun.* * EXCLUDE
com.ibm.* * EXCLUDE
org.eclipse.* * EXCLUDE
org.apache.* * EXCLUDE
org.w3c.* * EXCLUDE
org.xml.* * EXCLUDE
javax.xml.parsers.* * EXCLUDE
org.jboss.* * EXCLUDE
org.tanukisoftware.* * EXCLUDE
gnu.getopt.* * EXCLUDE
EDU.oswego.* * EXCLUDE

Any suggestions about how to reduce the size of the profile files would be
greatly appreciated. Thank you,

Ted Larson Freeman

Ted,

It's probably better to ask on the TPTP newsgroup, which I've added to
the "to" list of the reply. Paul invariably seems to answer all the
questions there. You might want to increase the heap size in your
eclipse.ini file when dealing with such big trace files.

Ted,

Here are some suggestions for you to consider:

1. For filters, try an "include list" approach as opposed to the
"exclude list" approach you are currently using.

For example, assuming all your application classes are defined under
package com.initech.*, use the following filter:

com.initech.* * INCLUDE
* * EXCLUDE

2. Start the profiler in "enabled" mode and then attach the workbench at
the point where your application starts working (i.e., skip the JBoss
initialization phases) or processes interesting requests. Then detach.

HTH,
Asaf

Thanks, Asaf! That's a big help.
