Prosess [pid] in timeline (tracelogger in ring mode)   
IDE401
when viewing a kev file generated from tracelogger in ring mode we see the string "Prosess" followed by [somepid] in 
timeline instead of OrigProcessName [pid].  Is it planed that we can change/edit the string
"Process" manually to real process name the case set, that there is a pretty  good reason for the things actually 
displayed as  "Prosess [pid]" in the timeline view ?

Thanks,
Jeevan

The reason for this is quite simple.
TraceEvents like "CreateProcessName" which the IDE takes the information about process names from, are triggered only 
once on tracelogger start/attach to procnto-instr by procnto itself.
If your trace now runs long enough, these events will be overwritten because you're running in "ring mode".
I don't now if QNX has a plan for making process names editable int the IDE, but what you can do, is to append 
appropriate "CreateProcessName" events to the tracefile, this is a bit tricky - but it works (we do this for threadnames
 on 6.3.0 which has no threadname support).

Hey HP - why not extend your util to add the process names too - then you could post it to the bazaar project. :-)

Re: Prosess [pid] in timeline (tracelogger in ring mode)   
I tryed to find an example on how to add a ProcessName Event at the end of a ringbuffered kernel event trace, but I 
couldn't find one. 
I managed to insert a PROCCREATE_NAME Event, but there is only one row in the traceprinter output (containing the ppid 
and pid, but not the name).

Could someone please post a small example, how add the process names?

Thank You!

I have some code around that adds thread names.  I can send that your way and
you should be able to adapt it to your needs.

Let me fish around for a few minutes...

Did you already find an example? 

Thank You!

okey dokey, here we go ...
see the attachment, it is an example of how to do this.
I didn't test this one 'til now - it'san adaption of a different function which is inserting thread names for traces of 
an 6.3.0 system.
But it should work - maybe except of compilation errors.
you will need to provide the list of names,  pids and ppids.
I hope the source is self explaining, if not and you have more question - just ask

Re: Prosess [pid] in timeline (tracelogger in ring mode)   
Thanks a lot! 
the source is pretty much self explaning. I did not know one has to mess around with this beg, cont & end header thing. 
This was one of the missing pieces...
To get it working for me (on a 6.3.2er version), I had to add 1 to the position of the last timestamp and to the "add 
the process names here" position in the file. Otherwise the timestamp was wrong and thus it was not possible to open the
 .kev file in the ide.

Thanks again! 

Greets,
Matthias Ecker
