You can see the output is in five columns.
|
||
|
|
||
|
The first column is CPU-id, the second is PID, third is the time since boot in
|
||
|
microseconds since the previous action. The fourth and fifth columns
|
||
|
represent the action happening. The Tcl command or procedure name is prefixed
|
||
|
by an indicator reprenting what is happening. These may be -> (procedure
|
||
|
entry), <- (procedure return), > (command entry), or < (command return).
|
||
|
|
||
|
As each action is taken, the fourth and fifth columns are indented by 2 spaces.
|
||
|
This shows which procedure or command is calling which.
|
||
|
|
||
|
If the output looks shuffled, check the CPU "C" and "TIME" columns, and
|
||
|
post sort based on TIME if necessary.
