Viewing common tabs for all node types

On the Nodes page, you can view the Overview, Hardware, Network, Storage, and Events tabs for all node types.

The StorageGRID Webscale system contains Admin Nodes, Storage Nodes, and, optionally, Archive Nodes and API Gateway Nodes.

Example Overview tab

On the Overview tab, you can view general information about each node, such as the name, software version installed, and any unacknowledged alarms for the node. If any alarms are listed, you can click the link in the Service column to get details about each alarm.

To display a different time interval, select one of the controls above the chart or graph. You can select to display the information available for intervals of 1 hour, 1 day, 1 week, 1 month, or 1 year. Or you can set a custom interval, which allows you to specify date and time ranges.

Example Network tab

The Network tab displays a graph showing network traffic for the node over time.

The Network Traffic graph indicates the total amount of network traffic across all of the network interfaces on the node. Communication to the node is "Received" and communication from the node is "Sent" or "Transmit."

Example Storage tab

Although the Nodes page for each node type contains a Storage tab, the information on that tab differs depending on the node type:
  • Admin Nodes, Archive Nodes, and Gateway Nodes each contain a list of disk devices and volumes on the node.
  • Storage Nodes contain graphs showing data storage and metadata storage used over time, as well as a list of disk devices and volumes on the node.

Example Events tab

The Events tab displays system events that help with troubleshooting. The Last Event provides an area of focus when an error occurs. After resolving issues, click Reset event counts to return the counts to zero. For details, see the information about troubleshooting.
Note: To reset event counts, you must be a user who belongs to a group that has the Grid Topology Page Configuration permission enabled.
