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.

Gravwell Ingester Preprocessors

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

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

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.
