After facing an enormous monthly bill at a major log aggregation provider, and suffering through a whole mess of frustration setting up open-source alternatives, I built Logmunch for anybody out there who wants unstructured, full-text search of their logs, in a package that’s easy to set up, fast, and free as in beer.
Logmunch can easily process 1MB/s of logs, running on a $4.11/mo VPS. Full-text search queries resolve in fractions of a second. Operators are standing by.
You're going to want to read the manual.
