One of the most popular syslog-ng destinations is Elasticsearch. Humio, a log management provider, supports a broad range of ingest options and interfaces, including an Elasticsearch-compatible API. Last week, Humio announced Humio Community Edition, which provides the full Humio experience for free, with some limitations on daily ingestion and retention time. I tested the Community Edition, and it works perfectly well with syslog-ng.
If you come from the Humio side, you might wonder what syslog-ng is.
