I'm just starting to mess about with dtrace on Solaris. How do I configure a probe in a PID provider dtrace script to trigger when the process being traced exits?
I've tried pid$1:::exit where $1 is the PID but I get
'exit' is an invalid probe name (0 Replies)
creatbyproc.d(1m) USER COMMANDS creatbyproc.d(1m)NAME
creatbyproc.d - snoop creat()s by process name. Uses DTrace.
SYNOPSIS
creatbyproc.d
DESCRIPTION
creatbyproc.d is a DTrace OneLiner to print file creations as it occurs, including the name of the process calling the open.
This matches file creates from the creat() system call; not all file creation occurs in this way, sometimes it is through open() with a
O_CREAT flag, this script will not monitor that activity.
Docs/oneliners.txt and Docs/Examples/oneliners_examples.txt in the DTraceToolkit contain this as a oneliner that can be cut-n-paste to run.
Since this uses DTrace, only users with root privileges can run this command.
EXAMPLES
This prints process names and new pathnames until Ctrl-C is hit.
# creatbyproc.d
FIELDS
CPU The CPU that recieved the event
ID A DTrace probe ID for the event
FUNCTION:NAME
The DTrace probe name for the event
remaining fields
The first is the name of the process, the second is the file pathname.
DOCUMENTATION
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
bose descriptions explaining the output.
EXIT
creatbyproc.d will run forever until Ctrl-C is hit.
