IPMI and Gravwell Part 1: Building an IPMI Ingester

Apr 8, 2021 11:45:13 AM / by Fritz posted in ingester, HOWTO, IPMI

(This post is part one of a two-part technology series around building and using an IPMI ingester and kit. Part two coming soon.)

In many data aggregation and analysis tools, the ecosystem is fully closed source, and often even data ingest protocols are proprietary. This means that if you want to ingest a novel data format of your own, you’re either, a) $%*! out of luck, or b) forced to collapse your data into some form of low performance, textual, line-delimited data that a generic log ingester will work with.

At Gravwell HQ, we take a different approach. All of our ingesters are open source and freely available under a BSD license, and our ingest framework is open and available as a Go library. In this post, we’ll be taking a tour of how we wrote a real and officially supported Gravwell ingester: the new Gravwell IPMI Ingester. We’ll cover how we manage configuration files, set up and manage indexer connections, and transform IPMI data into a flexible JSON schema before sending it out.

Overview

Today we are going to talk about something very important - beer.  Homebrewing has a long tradition and many master brewers started by making swill in their basement.  So today, I am going to go over my homebrew setup, how it is instrumented, how I use low-cost sensors to monitor every stage; and how a little bit of automation saved a kegerator and a few carboys.
