Intel® VTune™ Amplifier uses SCP as a mechanism to copy files to and from the host and the target system, while performing a remote collection.
Often, you may encounter an issue where VTune Amplifier will stop with the "Collection failed" error with a sub-message like:
Collection failed. The data cannot be displayed. Cannot copy [some_file] to [some_remote_destination] on target. Please check scp command.
As the error message says, you may first test if the SCP command works. To do this, you may try to copy a simple file:
scp -v my_file.txt user@remote_host:/home/[remote_user]/Desktop
For the above to work, you need to set up a password-less SSH connection to your remote host. (See the section "Setup target to not require a password" from this link for more information)
I have a file called
my_settings.txt on the desktop of my local machine and I want to copy that file on the Desktop of my remote machine with a hostname
remotetarget (mapped to an IP address in
/etc/hosts) and username
scp /home/hostuser/Desktop/mysettings.txt targetuser@remotetarget:/home/targetuser/Desktop/mysettings.txt
If the above command works, then you know SCP is working fine.
Often, SCP will fail without any meaningful error, with the verbose output finishing on
Exit status 0. The issue is based on a known bug reported here and is simply due to the remote shell outputting some text.
If when you do
ssh targetuser@remotetarget and you see some text being printed, you would want to log on the target machine and comment the outputs (defined in
Removing the printed outputs should resolve the SCP problem.
Another option could be to check if one is in an interactive shell through the
$PS1 variable and subsequently preventing the execution of the rest of the script. This can be done by adding the following on the first line of your
if [ -z "$PS1" ]; then return fi
