Verify Splunk operation using Python SDK

brent_weaver — Fri, 02 Feb 2018 23:00:38 GMT

I am working on a tool to validate that splunk is operational, both HEC and std Indexing (9997). HEC Is easy to do with either python requests or the SDK, but how can I script, in python, writing a test event directly to the indexes on port 9997? I assume that the SDK will be my friend!?!?! Any help is MUCH appreciated!

I have the following simple code:

#!/usr/bin/env python

import splunklib.client as client

HOST = "localhost"
PORT = 8089
USERNAME = "admin"
PASSWORD = "joniie"

# Create a Service instance and log in
service = client.connect(host=HOST, port=PORT, username=USERNAME, password=PASSWORD)

# Print installed apps to the console to verify login
for app in service.apps:
    print app.name

When I run this locally on the SPlunk test host (which has SDK installed) I get the following:

Traceback (most recent call last):
  File "./logger.py", line 11, in <module>
    service = client.connect(host=HOST, port=PORT, username=USERNAME, password=PASSWORD)

What am I missing? Why is this not working?

This seems to be related to Splunk 7.x tree and not my 6.5.2 systems. I remember that there is a big change in SSL/TLS from 6 -> 7 so that would make sense. So that being said, does anyone know how to work around this issue so I can use the SDK on 7.x?

Are you on CentOS or RHEL 7?
