Trace logger info during system boot up   
Hi,

I want to get trace logger info. during system boot up.
On one of the forum i seen below command which i included in the build script but it is not working. trace logger itself
 not yet started.
tracelogger -S10 &

Please suggest whats happening here also let me know any utility is there to work out which i can include on my build 
script so during boot up the trace logger will be automaticallly started and kev file will be available.

Thanks & Regards,
Robin

AW: Trace logger info during system boot up   
Hi Robin,
with -S you're telling tracelogger to use the given number as total logfile size.
10 Bytes is not very much :-)
In general you have two options:
1. tell tracelogger the max size of logfile to use
2. tell tracelogger the time to record, with infinite logfile size

1. traclogger -n0 -S10M &
2. traclogger -n0 -s20 &

the diff is that capital S is size in bytes and lower s is time in seconds.

For more information take a look at the ref manual
http://www.qnx.com/developers/docs/6.4.0/neutrino/utilities/t/tracelogger.html

BTW: if you want to trace your system startup you may be interested in the
combination of -M -S, which gives minimal impact to your system:
3. tracelogger -n0 -M -S20M &
will give you a logfile of 20MB in /dev/shmem/tracebuffer.kev
be aware that /dev/shmem is very transient

to be sure that tracing has ended I would recomment that you allways either check that tracelogger has exited by "pidin ar" or you just do a "slay tracelogger"

Re: AW: Trace logger info during system boot up   
Hi,

Thnx for your reply.

To my surprise i dont see any tracelogger running also there kev file s also not seen on the path. I suspect it could be
 a memory issue so reduced to even 1MB but still the same result. With pidin ar below are the process running.

     pid Arguments
       1 proc/boot/procnto-instr
       2 devc-seromap -u1 -F -e -S -b115200 0xfffb0000^2,46,k
       3 devf-generic -s0,32M -L1000 -r -f1
   16388 inflator -v /rodata
   16390 i2c-omap
   20487 dspmgr -i /proc/boot/dsp_image.out -p30 -s1280 -b5912 -v1
   32776 io-audio -odisable_sw_mixer -domap i2c_addr=26
   40965 ipcl -o speed=1000 -p45
   40969 devu-ohci -P25 -a0xfffba000 -i38 -vvvvvvvs
   61451 ksh ksh
   61452 PowerManagerProc -a1 -w1 -t2 -p50 -v

some things to check:
-what's the free mem after a normal startup -> pidin in
-is there any message on your console?
-just check a "tracelogger -n0 -s3.0 &" on your cmd line -> any error message?

Re: AW: AW: Trace logger info during system boot up   
Hi,

Below r the ans for your ques:

some things to check:
-what's the free mem after a normal startup -> pidin in - (Ans) - 11MB free
-is there any message on your console? - (Ans) - No messages on trace logger seen on the console.
-just check a "tracelogger -n0 -s3.0 &" on your cmd line -> any error message? - (Ans) - Working correctly. No error messages

FYI - I could get the kev files any where during my normal operation apart from system boot up.

AW: AW: AW: Trace logger info during system boot up   
anyway
what's the exact cmd line your using?
do you realy use /dev/shmem as destination or do you use -f filename ?
maybe your destination filesystem is yet not present when you're invoking tracelogger

Re: AW: AW: AW: Trace logger info during system boot up   
Hi,

I have one more question. Is it possible to stop the trace logger at user convenient time (from software).

Say i have to stop the trace logger if some event has occured.

If so pls let me know the util.

Thanks,
Robin
