Configure the Custom Collector

import os

def main():
    cmd = os.environ['AMPLXE_COLLECT_CMD']
    if cmd == "start":
        path = os.environ['AMPLXE_DATA_DIR']
        #starting collection of data to the given directory
    elif cmd == "stop":
        pass #stopping the collection and making transformation of own data to CSV if necessary

main()

if "%AMPLXE_COLLECT_CMD%" == "start" goto start
if "%AMPLXE_COLLECT_CMD%" == "stop" goto stop
echo Invalid command
exit 1

:start

Launch the Custom Collector

Click the
Configure Analysis
button on the toolbar.
The Configure Analysis window opens.
Make sure the correct target system and target type are selected in the
WHERE
and
WHAT
panes.
In the
Advanced
section of the
WHAT
pane, edit the
Custom collector
field to add a command launching your external collector, for example:
on Windows*:
python.exe C:\work\custom_collector.py
on Linux*:
python home/my_collectors/custom_collector.py
From the
HOW
pane, select the required analysis type, for example,
Hotspots
.
Configure available analysis options as you need.
Click the
Start
button to launch the
VTune
Profiler
analysis and collect custom data in parallel.
VTune
Profiler
does the following:
Launches the target application, if any, in the suspended mode.
Launches the custom collector in the attach (or system-wide) mode.
Switches the application to the active mode and starts profiling.
If your custom collector cannot be launched in the attach mode, the collection may produce incomplete data.
