Viewing details of WAF node

Details of installed the WAF node are displayed in the table and card of each WAF node. To open the card, click the appropriate table record.

The following node properties and metrics are available:

  • Node name that was given to the node upon creation

  • The average number of requests per second (RPS)

  • Node IP address

  • Unique node identifier (UUID)

  • Token of the cloud WAF node

  • Time of the last synchronization of the WAF node and Wallarm cloud

  • Date of the WAF node creation

  • Number of requests processed by the node in the current month

Cloud WAF node card

If one cloud WAF node is installed for multiple instances, then the corresponding number of WAF nodes is grouped into one record in the table. Properties and metrics will be available for each instance.

Regenerating the token for cloud WAF node

Token regeneration creates a new token for the node.

  1. Open Wallarm UI → Nodes.

  2. Click Regenerate token in the cloud node menu or card.

  3. If the cloud node is already installed in your infrastructure, copy the new token value and specify it within the installed node settings.
