View a Message

Messages are displayed in a table format. By default, this table is sorted by date, from the newest to the oldest. All columns, except for the Actions column, can be sorted in ascending () or descending () order by clicking the () icon. The triangle icon indicates which column is being sorted currently.

Each line in this table corresponds to a message.

Messages can come from the following sources

  • External server — These messages are sent from LevelBlue. Every hour the system checks if there are new messages. The server hosting the message is, which uses port 443. The external server signs all messages and USM Appliance checks the signature to verify the authenticity.
  • System status — These messages correspond to the operation of USM Appliance in real time. For this reason, they update frequently.

    They consist of the following status types:

    • Backup task in progress.
    • One or more plugin configuration files have been deleted.
    • Unable to analyze all network traffic.
  • User Activity — These messages correspond to user activities within USM Appliance. For example, when a user executes a backup on Configuration > Administration > Backups, and the backup ends with an error, this will generate a message.
