Jan 19, 2021 9:51:59 AM / by Fritz posted in Data Fusion, Software Updates, Logging

Gravwell 4.1 introduces a new module - Enrich - that can add static data to every entry in a query. Sometimes you need to add static data to a dataset, such as the standard deviation itself across all entries in the dataset or annotations about the query, or you may want to fuse several data points from a resource. The enrich module provides this simple but important feature.

4.1.0 Feature Spotlight: Upload Data from the Gravwell UI

Jan 12, 2021 8:54:36 AM / by John Floren posted in Software Updates, ingester, pcap

Sometimes, you just need to get data into Gravwell without setting up any ingesters--maybe you want to analyze a collection of log files somebody emailed you, or maybe you've got a pcap file from Wireshark. We've had command-line tools for this for years, but with Gravwell 4.1.0 we're pleased to announce a new feature: a flexible and easy-to-use interface for ingesting data inside the web interface! This UI lets you drag-and-drop line-delimited logs, packet capture files, or entries downloaded from a Gravwell query; Gravwell will figure out what you gave it and parse it appropriately.

Introducing Gravwell Macros

Nov 27, 2019 9:24:55 AM / by John Floren posted in Software Updates

One of the exciting new features in Gravwell 3.3.0 is search macros. Anyone who's experimented much with Gravwell knows you may often end up crafting a long and complex regular expression which you'll want to use over and over, but such a long regex makes the query hard to work with. Macros let you turn that long regular expression (or any other part of a search query) into a much shorter name you can use again and again.

Feb 27, 2019 10:51:08 AM / by Kris Watts posted in Software Updates

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.
