Gravwell Ingester Preprocessors

Mar 30, 2020 10:05:08 AM / by John Floren posted in ingester

0 Comments

Gravwell's ingesters can pull data from a wide variety of sources and we advocate keeping raw data formats for root cause analysis, but sometimes it's nice to massage the data a little before sending it to the indexers. Maybe you're getting JSON data sent over syslog and would like to strip out the syslog headers. Maybe you're getting gzip-compressed data from an Apache Kafka stream. Maybe you'd like to be able to route entries to different tags based on the contents of the entries. Gravwell's ingest preprocessors make this possible by inserting one or more processing steps before an entry is sent upstream to the indexer.

Fighting social media propaganda

Feb 19, 2019 9:55:00 AM / by John Floren posted in Software Updates, ingester, reddit

0 Comments

We're continuing to work with investigative reporters to research unscrupulous activity on social media. Most recently, Engadget published a piece on nefarious political influencers on Reddit. We’ve written in the past about analyzing social media comments, but didn’t make the ingesters publicly available. With an increasing need for research in this area, we decided that releasing our Reddit and Hacker News ingesters could help new users get started with Gravwell even faster, so we open-sourced them. Read on to learn how to get the ingesters, how to run them, and how to get started with the data.

Gravwell And Docker Deployment

Apr 5, 2018 3:50:03 PM / by Kris Watts posted in DevOps Analytics, ingester, Logging, automation, docker, cluster

Update (1/24/2019)

This post is mostly about building your own docker images. If you're interested in getting up and running fast using Gravwell+Docker, head over to our docs that cover our pre-built images: 

https://dev.gravwell.io/docs/#!configuration/docker.md

Overview

For this blog post we are going to go over the deployment of a distributed Docker-based Gravwell cluster. We will use Docker and a few manageability features to very quickly build and deploy a cluster of Gravwell indexers. By the end of the post we will have deployed a 6 node Gravwell cluster, a load balancing federator, and a couple ingesters. Also, the six node “cluster” is also going to absolutely SCREAM, collecting over 4 million entries per second on a single Ryzen 1700 CPU. You read that right, we are going to crush the ingest rate of every other unstructured data analytics solution available on a single $250 CPU.  Lets get started.
