Graylog Sidecar is a lightweight management service that you install on each host for the central control and monitoring of log collector processes, including Filebeat, Winlogbeat, and Auditbeat. Sidecar eliminates the need to configure and maintain collectors on each server by allowing you to define reusable, centrally managed configurations in the Graylog interface. These configurations can be deployed across many hosts using tags, ensuring consistent behavior and reducing administrative overhead.
