MH-13487 Initialize this repository

[pmiddend]

MH-13483 introduces basic statistics visualization facilities into Opencast. In particular, a statistics provider implementation for InfluxDB 1.x time series is provided, i.e. Opencast can visualize InfluxDB time series data.

The Opencast InfluxDB Adapter (this pull request) is implemented as a standalone Java application that continuously parses the Apache log files HTTP access logs to gather data about the usage of assets (here: "Views" of video files) and feeds those info into InfluxDB.

The adapter optionally uses the External API to find out to which series a given event belongs so that view data can be aggregated on series level, too.

Currently implemented feature set:

• Both single- and multi-tenant support
• External API integration to retrieve additional metadata from Opencast (series)
• Dynamic time window analysis of HTTP accesses to heuristically determine "number of views" (access to the same resource within a given time window don't count as multiple views)
• Some filter options to ignore requests that should not be counted

Current limitations:

• The adapter is implemented for a specific Apache log format. In theory, it could be generalised to support other log formats, web servers or even to a general line-based log analyzer. This is, however, not in the scope of this work.

This work is sponsored by SWITCH.

@wsmirnow @staubesv I'm assuming that Plapadoo and co should have write access to this repo. I've given @doofy and @pmiddend write for this repo. Anyone else needed?

Hi Greg, you can grant write permissions to all Opencast developers. But it will take a while. Doing it on demand is also an option. No really, I havn't a strong opinion about that. It is ok, if the main developer have write access to this repo.

@gregorydlogan I would say that all Opencast committers should have write access to this repo.

[gregorydlogan]

@staubesv @wsmirnow committers already have write access, but @pmiddend didn't. @doofy already did, but I forgot he was a committer :)

@wsmirnow What is the status of this review?

[wsmirnow]

Looks fine for me. I havn't run this code but the build was successfull.

Thanks for the review!
