Amplifier cannot detect remote machine configuration.

[Agarwal__Mayank]

I am trying to use VTune to get memory consumption for my binaries. I have installed VTune on windows and trying to connect to (remote SSH) linux to get the results. However it doesn't move past the first step and gives the error - "Amplifier cannot detect remote machine configuration."

From your another thread I picked a command

INSTALL_VTUNE_DIR/bin64/amplxe-python INSTALL_VTUNE_DIR/bin64/amplxe-runss.py --no-modules --log-folder=WRITABLE_FOLDER --target-system=ssh:USER@TARGET_IP --target-install-dir=/opt/intel/vtune_amplifier_2018.3.0.566015 --ui-output-format xml --context-value-list

These logs are repeated for few times (may be retries) but doesn't exit with specific error. Do you think these are permissions issue?

Hi.

What version of VTune do you use?

Could you try the last VTune from vtune.intel.com and share amplxe-python output one more time?

Is it the same message in output if you try to use VTune/bin64/ssh.exe directly?

Thanks, Kirill

[Agarwal__Mayank]

I am using 2019 Update 8

If I try to ssh.exe directory this is what I get but yes it can successfully login into the host. The bold ones are inputs provided by me.

The authenticity of host '<<HOSTNAME>> (X.Y.Z.A)' can't be established.
RSA key fingerprint is xxx.
Are you sure you want to continue connecting (yes/no)? yes

<<PasswordForUser>>

[Kirill_U_Intel]

ok, let's try to use VTune keys to check passwordless connection

ssh -o BatchMode=yes -o ServerAliveInterval=5 -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o ConnectionAttempts=1 <USER>@<MACHINE-NAME> -i %USERPROFILE%\.ssh\id_rsa_vtune_<USER>@<MACHINE-NAME> "echo Hello"

where

"%USERPROFILE%\.ssh\id_rsa_vtune_<USER>@<MACHINE-NAME>" is private key that was generated by VTune automatically.

[Agarwal__Mayank]

It connects to linux and in fact post asking me password it adds public key to the authorized_keys file as well on linux. But it still remains stuck. I ran amplxe-python as well to collect the logs.

In amplxe_runss.py.12376.logssh and it shows a lot of these files with suffix as 'log0, 1, 2....

Warning: Permanently added '<HOST_NAME>,<IP>' (RSA) to the list of known hosts.
dup - ERROR: DuplicatedHandle() :6
fcntl(-2, F_GETFL): Bad file descriptor

You can see amplxe_runss.py.12376 attached along with this thread. It looks like it keep on trying ssh post that as I lots of amplxe_runss.py.12376.logssh.log{N] files being made and each of them has this above exception.

[Kirill_U_Intel]

To be clear.

• do you have public key on the target linux? something like "ssh-rsa bla-bla-bla vtune" in /home/USER/.ssh/authorized_keys
• do you still need to set password to get access to the remote linux? Please, provide output for 'ssh <USER>@<MACHINE-NAME> -i %USERPROFILE%\.ssh\id_rsa_vtune_<USER>@<MACHINE-NAME> "echo Hello"'

We could not run collection without passwordless access and looks like something wrong here

Re: do you have public key on the target linux? something like "ssh-rsa bla-bla-bla vtune" in /home/USER/.ssh/authorized_keys

Yes

Re:  do you still need to set password to get access to the remote linux? Please, provide output for 'ssh <USER>@<MACHINE-NAME> -i %USERPROFILE%\.ssh\id_rsa_vtune_<USER>@<MACHINE-NAME> "echo Hello"'

No I don't need to enter password to get access. It works just fine.

Are there authorised output in this case?

Yeah I do get the above warnings :)

[Kirill_U_Intel]

Did VTune copy /home/<USER>/vtune_amplifier_2019.8.0.604197/vtune_amplifier_target_x86_64.tgz on the target?

Could you unpack it directly? 

tar xf /home/<USER>/vtune_amplifier_2019.8.0.604197/vtune_amplifier_target_x86_64.tgz -C /home/<USER>/vtune_amplifier_2019.8.0.604197/

[Kirill_U_Intel · Accepted solution]

Do you have disk space enough?

VTune try to copy C:\\Program Files (x86)\\IntelSWTools\\VTune Amplifier 2019\\target\\linux\\vtune_amplifier_target_x86.tgz and C:\\Program Files (x86)\\IntelSWTools\\VTune Amplifier 2019\\target\\linux\\vtune_amplifier_target_x86_64.tgz to /home/<USER>/vtune_amplifier_2019.8.0.604197/

and unpack them there.

Can you copy and unpack manually?

[Agarwal__Mayank]

It gets copied on to linux and gets inflated as well

Let's check that collector is ok.

Could you run /home/<USER>/vtune_amplifier_2019.8.0.604197/bin64/amplxe-runss --context-value-list?

What is target system? What is version of glibc ' /lib64/libc.so.6  -v'?

[Vitaly_S_Intel]

It looks like you're using pretty old Linux which is not supported by VTune. Which one is it?

VTune 2019 supports RHEL 6 & 7. The problem is that VTune binaries are built on RHEL6 - so, they won't execute on RHEL5.

You probably need to take an older VTune version.

[Agarwal__Mayank]

Do you think you can point me to the relevant installer/download for VTune Profiler version?
