This repository contains open-sourced libraries and commands developed by Gravwell.

There are a selection of Gravwell-specific libraries and tools:

• ingest/ contains the ingest library, which is used to connect to a Gravwell indexer and upload data.
• ingesters/ contains the source code for Gravwell ingesters.
• generators/ is a collection of tools that generate artificial data for testing Gravwell or any other log analytics system.
• manager/ provides a very simple init command which we use in Docker containers.
• chancacher/ implements a caching library we use for ingesters.

There are also a few libraries which may be of use outside Gravwell-specific applications:

• filewatch/ is a library that can monitor files on the filesystem for changes; we use this in the FileFollow ingester.
• timegrinder/ is a timestamp extraction library we use to extract timestamps from arbitrary data
• ipexist/ contains a library for efficiently storing and checking for the existence of an IPv4 set with high density sets.
• winevent/ is a library which can interact with the Windows Event subsystem to extract XML rendered events.
