Basic utility to query the Splunk management REST interface with valid credentials.
Users can pull back a bit of data but probably want admin permissions (see here) to get interesting data, and the management port 8089 needs to be exposed.
If you're on a local instance, you may need to specify localhost:8089 instead of cloudinstance.splunkcloud.com:8089.
./splunkon https://instance.splunkcloud.com:8089/ username password
JSON file with the entire (very verbose) Splunk responses logged to splunkon.json
$ ./splunkon https://localhost:8089 admin password123
