23.03

Update 01-inputs.pfelk

fixed #470

22.04

Incorporated default security (elastic) into the pfelk repo. Added more steps and inhibited script from doing a complete installation but it's a simple solution to getting started with OPNsense & pfSense remote logging.

22.01

Data Streams, native ILM support and various tidying (more efficient logging)

v20.3

Various updates and tweaks. This release was to capture the past several months of revisions. Additionally, the file structure was amended to allow for a more seamless install (docker/host). The pipelines.yml file points to the new conf file location (/etc/pfelk/conf.d) and those wishing to add multiple pipelines (e.g. Wazuh etc..) can now amend the pipelines.yml for additionally pipelines while utilizing the default conf.d folder (doesn't conflict with pfelk).
