Error initializing Python driver object, init() returned FALSE; driver='s_r2s#0'

Hi, I seem to be unable to get this working. I followed the instructions, but syslog-ng won't start.

config is pretty simple:

source s_r2s {
    python(
      class("r2s.source.REST2SyslogSource")
      options("interval",60)
      options("auth_url","https://api.opsgenie.com/v2/logs/")
      options("alerts_url","https://api.opsgenie.com/v2/logs/")
      options("api_key","XXXXXXXXX")
    );
};

destination d_tcp { syslog("127.0.0.1" transport("tcp") port(514) ); };

log {source(s_r2s); destination(d_tcp); };

• CentOS 7
• Python 3.6
• syslog-ng 3.28

@mjknoxie in order to work with R2S you will need to implement 3 classes:
a class that inherits from R2SAPIAdaptor - responsible for constructing the URLs and calling the REST endpoints
a class that inherits from R2SItemFormatter - responsible for parsing the response (each of the returned items)
and a class that inherits from R2SAPIPaginator - responsible for implementing the pagination strategy (usually, the REST API will provide a limited set of items per page, hence there is a need to paginate through all pages)

you can review the base classes under: r2s/extensions/abstract.py

You can see example for each of this custom class under: r2s/extensions/proofpoint/pcasb where we have 2 extensions: one that fetched alerts (using a page num pagination strategy) and another extension which fetch system events (using a next_page token strategy).

also you will need to add the extension name and class paths in the syslong config file (the readme shows and example of that)
