Displaying DTrace Consumers
To extract DTrace data from a DTrace consumer, you must first determine the DTrace consumer of interest by running the ::dtrace_state
MDB dcmd
:
> ::dtrace_state ADDR MINOR PROC NAME FILE ccaba400 2 - <anonymous> - ccab9d80 3 d1d6d7e0 intrstat cda37078 cbfb56c0 4 d71377f0 dtrace ceb51bd0 ccabb100 5 d713b0c0 lockstat ceb51b60 d7ac97c0 6 d713b7e8 dtrace ceb51ab8
This command displays a table of DTrace state structures. Each row of the table consists of the following information:
-
The address of the state structure
-
The minor number associated with the
dtrace
device -
The address of the process structure that corresponds to the DTrace consumer
-
The name of the DTrace consumer (or
<anonymous>
for anonymous consumers) -
The name of the file structure that corresponds to the open
dtrace
device
To obtain further information about a specific DTrace consumer, specify the address of its process structure to the ::ps
dcmd:
