Summary of Commands trace
UCS 1000 R4.2 Administration 585-313-507 Issue 3 April 2000 609
• Use the sleep argument of the trace command to decrease the time that
trace sleeps between reading the buffer. The default sleep time is 200
milliseconds.
• Increase the size of the trace buffer by adding or modifying the line
TRACE_BUFFER_SIZE=X in the /vs/data/irAPI.rc file, where X is the
number of messages that the trace buffer can hold. The default is 256.
Increasing the value of X should reduce the chance of losing trace
messages.
! CAUTION:
If you change the size of the trace buffer, you must stop and restart the voice
system (stop_vs and start_vs). Otherwise, you will not be able to run trace.
Examples
The following are examples of valid level lists and ranges:
1,2 Trace levels at 1 and 2
1-4,FE Trace at levels 1, 2, 3, 4, and 20
all Trace at levels 1-32.
Note: Levels are not hierarchically inclusive. That is, level 3 does not
imply that tracing at levels 1 and 2 also occurs, which could be
achieved by using a range starting from 1. For example, 1-3 for
levels 1, 2, and 3.
