Managing Deciders
The Traffic Manager manages the vWAF cluster automatically. Any problems that arise with the cluster are reported on the Traffic Manager Admin UI and can be resolved from there.
If you need to manage your cluster manually, please contact your support provider.
CAUTION Use the Decider Cluster Nodes tab in Cluster Management for information purposes only. Do not edit your configuration here unless you were advised otherwise by your support provider.
Retrieving statistics
You can check the load and availability of resources on any decider node at a glance, without having to log in to each node manually.
To display a detailed, graphical statistics view for a particular node:
- In the Action column, click the View Statistics icon.
- From the Time period drop-down list, select the period for which you want the data to be shown.
At the top, the statistics view lists precisely which version of vWAF is running on the decider node.
Below this version data, there are the following diagrams:
Diagram | Meaning |
|---|---|
Combined requests | Distribution of requests (accepted + denied) per minute that have been handled by this decider node. |
System load | Distribution of CPU load on this node. |
Free disk space for logs | Available disk space for log files along time. |
Free physical system memory | Available free physical system memory along time. |
Average disk space for logs | Average available disk space for log files within the selected Time period. |
Average physical system memory | Average available physical system memory within the selected Time period. |
Filtering the display
If you have a large cluster with many cluster nodes, you might like to filter the list of nodes so that you can find specific nodes more quickly.
To filter the list, disable the corresponding options shown on top of the list:
- Disable the option show running to hide all nodes that are up and running correctly.
- Disable the option show degraded to hide all nodes that are enabled but not running.
- Disable the option show disabled to hide all nodes that are disabled.
You can freely combine these options. The options are retained until you log out, but when you log in at a later time, all nodes will be visible again.
