Loki OSS is just a sales pitch for their managed service. It doesn't work well without dedicating significant time tweaking and configuring it. Documentation is confusing at best if you want to do anything serious. You have to also be ready to handle support calls if you open it up for others to use, because it WILL have issues fairly regularly if you have a good volume of logs and query range is more than a day or two.

Unless you have the bank to go with their managed service, don't bother.
