Python Support

Python is supported out of the box without users having to modify their containers, code, SDKs or anything else. Just deploy the Polar Signals Agent and you're done.

Supported Versions​

3.6.0 - 3.12.x

Troubleshooting​

The agent determines whether a process is a Python process by checking if the main binary starts with python or if there is a dynamically linked library, that contains libpython.

$ ldd /path/to/python
❯   linux-vdso.so.1 (0x00007fffccf70000)
    libpython3.11.so.1.0 => /path/to//libpython.so (0x00007f2bf8800000)
    libm.so.6 => /usr/lib/libm.so.6 (0x00007f2bf8713000)
    libc.so.6 => /usr/lib/libc.so.6 (0x00007f2bf8531000)
    /lib64/ld-linux-x86-64.so.2 => /usr/lib64/ld-linux-x86-64.so.2 (0x00007f2bf8e68000)

If a process has been identified as a Python process, the agent logs if it fails to detect the version, or any other information it requires for successfully profiling it. Check the logs once you've verified that the main binary either starts with python or it dynamically links a libpython object.
