Python Versions in Splunk 8.0

sarvesh_11 — Tue, 18 May 2021 12:02:18 GMT

Hello Splunkers!

Wish You are safe and healthy from this pandemic.

I am using Splunk 8.0 Version, because it gives the flexibility with Python Versions (Python 2 and Python 3).

I have 2 different Splunk Applications, that gives me scripted inputs.

1 of the app executed on Python 2.7.17 and another runs on Python 3.7.17

How can i achieve the inputs from both of these apps?

Hi @sarvesh_11,

probably (I never tested it!) you could have two python instances, but my hint is to migrate as soon as possible the old one to the last Python version, because in few time Python 2 will be out.

Ciao.

That’s the last option I am left with.

but I wonder, why Splunk 8.0 embedded with 2 Python versions, if this usecase is not possible.

Hi @sarvesh_11,

Splunk 8 has both the versions for retro compatibility but, for my knoledge, you can enable only one of them.

Did you tried the Python3 script with the Python2 interpreter?

Ciao.

No I did not.

Is there any handy doc or some link to which I can refer and resolve.

if that resolves, that would be great help.

TIA,

Hi @sarvesh_11 ,

You can try modifying app.conf for a specific app under the install stanza:

python.version = {default|python|python2|python3} * When 'installit.py' exists, selects which Python version to use. * Set to either "default" or "python" to use the system-wide default Python version. * Optional. * Default: Not set; uses the system-wide Python version.

https://docs.splunk.com/Documentation/Splunk/latest/admin/appconf#.5Binstall.5D

This will apply the change only to that app and leave your other app with the default python version from your default server.conf.

Cheers,

David

No @DavidHourani , that doesnt solves it.

I gave python.version in both app.conf for different application, but unable to execute Python3 scripts.
