LogScale Configuration Parameters

Below is an alphabetical list of all of the Configuration Parameters (environment variables) used to configure LogScale on your Infrastructure. These are parameters that are exclusively related to LogScale software, as well as options that are related to other systems that integrate with LogScale (e.g., Amazon AWS, Google Cloud). Click on the name of a variable below for more details on it, along with related and similar options.

Use a simple text editor to open the LogScale configuration file, server.conf in the /etc/humio directory, and to change any of these variables on an installation of LogScale software. Once you've finished making changes, be sure to restart LogScale, depending on how you deployed it, for the server — or for each node affected in a cluster, if not all nodes.
