Humio

The integration between Humio and Fylamynt provides users with the ability to automate and streamline cloud log management.

Overview

Humio is powerful and extremely useful for system administrators. It provides a fast, flexible platform for logs and server metrics. With Humio Cloud, your log entries and other metrics are sent to your own private, secure repository. You’ll then use the Humio web interface to analyze your data and to create alerts to let you know when events occur or parameters are exceeded.

The alerts can be later ingested by Fylamynt with this integration and relevant information can be retrieved actively in the middle of any investigation from Fylamynt.

Use Cases

• Trigger a workflow in Fylamynt, when a specific Humio Alert goes into the state of ALERT.
