Intel(R) Trace Collector Configuration
NOTE
In some cases correct order of messages can be lost and you can get a message about
reversed timestamps:
[0] Intel® Trace Collector WARNING: message logging: 168 different
messages, 0 (0.0%) sends without receive, 5 (3.0%) receives without send,
163 (97.0%) messages with reversed time stamps.
To avoid this issue, include the first communication into the first time window.
Example
TIME-WINDOWS 0:1,10:20
In this case, Intel Trace Collector will trace the first communication, the events from the
beginning to the first second and the events from the 10th to the 20th second.
TIMER
Syntax
TIMER <timer name or LIST>
Variable
VT_TIMER
Default
gettimeofday
Description
Intel Trace Collector can use different sources for time stamps. The availability of the different
timers may depend on the actual machine configuration.
To get a full list, link an application with the Intel Trace Collector, then run it with this
configuration option set to LIST. By setting the verbosity to 2 or higher, you get output for each
node in a cluster. If initialization of a certain timer fails, no error messages are printed in this
mode and the timer is specified as unavailable. To see error messages, run the program with
TIMER set to the name of the timer that you want to use.
TIMER-SKIP
Syntax
TIMER-SKIP <number> 0
Variable
VT_TIMER_SKIP
