View Device Logs

GigaVUE‑FM provides the ability to view logs for each device/cluster node. These logs list all the user events and enable Gigamon Technical Support to troubleshoot in case of any problems.

Note:  Log streaming is supported on HC Series devices only.

In addition to describing how to view logs, this section describes the following supported functionality related to understanding and configuring the Logs view.
