Following is the command I used to get data related to the DataFlowEngine.
I wanted to know the % usage of cpu and memory.
This command will show the processes with its PID as :
Now I want the further details related to that PID that I can get after searching in ps -elf table.
How to use the output of above given command (ps avg | grep Data) as input to the ps -elf and then filter the PID and Process Name using one line command?
If script then it would be ok as well.
I know we can use awk or sed command to filter that.

Hi,
Wondering if anyone could help me with a simple script to filter out multiple things from a file.

If that makes sense. Basically a... (2 Replies)
I have ran into a small issue and I am not sure how to fix it.
In one of our current scripts we have this line which does a grep to get the pid of the process.
ps -ef | grep nco_p_syslog | grep $x | awk '{print $2}'
However this is not returning anything due to the how long the value... (7 Replies)

dapptrace
dapptrace(1m) USER COMMANDS dapptrace(1m)NAME
dapptrace - trace user and library function usage. Uses DTrace.
SYNOPSIS
dapptrace [-acdeFlhoU] [-u lib] { -p PID | command }
DESCRIPTION
dapptrace prints details on user and library function calls. By default it traces user functions only, options can be used to trace library
activity.
Of particular interest is the elapsed times and on cpu times, which can identify both function calls that are slow to complete, and those
which are consuming CPU cycles.
Since this uses DTrace, only users with root privileges can run this command.
OPTIONS -a print all details
-b bufsize
dynamic variable buffer size. Increase this if you notice dynamic variable drop errors. The default is "4m" for 4 megabytes per CPU.
-c print function call counts
-d print relative timestamps, us
-e print elapsed times, us
-F print flow indentation
-l force printing of pid/lwpid per line
-o print on-cpu times, us
-p PID examine this PID
-u lib trace this library instead
-U trace all library and user functions
EXAMPLES
run and examine the "df -h" command,
# dapptrace df -h
examine PID 1871,
# dapptrace -p 1871
print using flow indents,
# dapptrace -Fp 1871
print elapsed and CPU times,
# dapptrace -eop 1871
FIELDS
PID/LWPID
Process ID / Lightweight Process ID
RELATIVE
relative timestamps to the start of the thread, us (microseconds)
ELAPSD elapsed time for this system call, us
CPU on-cpu time for this system call, us
CALL(args)
function call name, with some arguments in hexadecimal
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
dapptrace will run forever until Ctrl-C is hit, or if a command was executed dapptrace will finish when the command ends.
