TIME-WINDOWS (Experimental)

Syntax
TIME-WINDOWS <time_value1>:<time_value2>[,<time_value1:time_value2>]
See the description of the time format in Time Value.
Variable
VT_TIME_WINDOWS
Description
Use the
TIME-WINDOWS
option to set up a time frame within which the Intel® Trace Collector will save the events into the trace file. When
TIME-WINDOWS
is not set, Intel Trace Collector collects the whole trace.
To set several time windows, use the necessary number of time frames separated by commas.
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. The time of the first communication depends on the application.
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 10
th
to the 20
th
second.
