Node
Browser limitations require configuring a specific port in order for these graphs to display properly. The Node and Graphs options are disabled until a port is specified in records.config (in /opt/WCG/config, by default).
- Update this variable to enable the Node and Graphs pages:
proxy.config.admin.overseer_port INT ##
where ## is a valid port number.
- Restart Content Gateway.
If the node is part of a cluster, two sets of statistics are shown:
- Information about the single node and
- Information showing an average value for all nodes in the cluster. Click the name of a statistic to display the information in graphical format.
