How can I find out why one of my vxWorks tasks was delayed?

Question

In vxWorks, I can issue the "i" command in the shell, and I get a list of tasks on my system along with some information, for example, the following example:

  NAME ENTRY TID PRI STATUS PC SP ERRNO DELAY
---------- ------------ -------- --- ---------- ------- - -------- ------- -----
tJobTask 1005a6e0 103bae00 0 PEND 100e5860 105fffa8 0 0
tExcTask 10059960 10197cbc 0 PEND 100e5860 101a0ef4 0 0
tLogTask logTask 103bed78 0 PEND 100e37cd 1063ff24 0 0
tNbioLog 1005b390 103bf210 0 PEND 100e5860 1067ff54 0 0

For tasks that have been postponed, I would like to know what they are superimposed on.

Is there any way to do this?

Answer 1

The w command will do exactly what you want:

  NAME ENTRY TID STATUS DELAY OBJ_TYPE OBJ_ID OBJ_NAME
---------- ---------- ---------- ---------- ----- ----- ----- ---------- --------
tJobTask 0x1005a6e0 0x103bae00 PEND 0 SEM_B 0x10184088 N / A     
tExcTask 0x10059960 0x10197cbc PEND 0 SEM_B 0x10183ff8 N / A     
tLogTask logTask 0x103bed78 PEND 0 MSG_Q (R) 0x103be358 N / A     
tNbioLog 0x1005b390 0x103bf210 PEND 0 SEM_B 0x103bf198 N / A
