This week sees the release of Gravwell 3.3.9, our last planned release prior to the 3.4.0 "Big Bang" release. The Big Bang release will introduce Gravwell kits (our way of providing pre-packaged dashboards, resources, SOAR scripts, and more) plus lots of new user interface features. But first, let's talk about 3.3.0. This relatively boring release is mostly comprised of bug fixes, a new timegrinder timestamp, and one UI tweak. Full change log available here.

We are excited to announce the immediate availability of Gravwell version 3.3.0. This release being a Minor release features a few fairly significant features and a whole heap of bug fixes and performance improvements. Over the next couple of days we will be doing a series of blog posts for this release detailing each of the new things in Gravwell, but first we need need to show off the centerpiece of this release, Overwatch.
We proud to announce the immediate availability of Gravwell version 3.2.3. This release is all about performance and bug fixes, but we did manage to slip in a new Kafka ingester.
We are pleased to announce the immediate availability of Gravwell version 3.2.2!
This one got away from us a bit and probably should be a major release, there is just too much good stuff in here. I tried to convince the team that we should just jump to version 10, but as our GUI lead started choking and muttering something about C'est absurde we decided to stick with a point release.
We've had some benchmarking requests from multiple organizations struggling with ingest performance from Elasticsearch, so we're publishing them here. The latest Gravwell release marks a significant improvement in ingest and indexing performance and this post covers the nitty gritty details. Better ingest performance means reduced infrastructure cost, less dropped data, and faster time-to-value. See how Gravwell stacks up.
We are excited to introduce autoextractors with Gravwell version 3.0.2. Autoextractors make it easy for regex gurus and binary ninjas to generate extractions and share them in a portable format. Autoextractors can dramatically simplify the process of performing field extractions from unstructured data without complicated time-of-ingest data definitions; they can built and shared by ninjas and and used by us mere mortals.
In this detailed technical guide we’ll cover analyzing Bro security analytics with Gravwell. Bro is a passive network security sensor designed to provide a plugin friendly detection framework. There are a myriad of commercial Bro vendors and almost as many ways to format and store the output. Gravwell provides an efficient and simple interface for acquiring, storing, and querying Bro data.
DNS auditing is an integral part of any I.T. security program. Name resolutions can act as a great tip for discovering malware, command and control streams, or misbehaving employees. Acquiring DNS audit data can be difficult with some DNS servers (*cough* Windows *cough*); for this post we are going to show an extremely easy method of getting DNS audit data directly into Gravwell.
To celebrate the release of the Gravwell Community Edition we are also releasing a standalone collectd ingester. Collectd is an excellent tool for monitoring the health of hardware, systems, and applications. For this post we will be demonstrating the installation and configuration of collectd to monitor the health and status of a few machines. We will be providing dashboard import codes so that you can quickly and easily import our ready made dashboards. The collectd ingester is part of the core suite of ingesters and is open source on github.
Back when we released the first version of Gravwell we immediately began sharing with friends and colleagues. Those initial testers primarily used Gravwell to monitor their home networks. They found rogue devices, neighbors leaching WiFi, poorly behaving IOT devices, and even some children that were playing video games when they should have been in bed. There was one problem, our friends wanted to give Gravwell to their friends but we aren't really a consumer software company. Our from-scratch secret sauce is what enables such game-changing pricing for larger enterprises but because we don't price on the data drip model it doesn't work for very small deployments. All that changes with the community edition...
