Viewing Node Metrics

Monitoring Node Metrics Using the Control System

By default, the page displays charts that show metrics for the last 24 hours. You can select a preset or specify a custom time range.

You can also zoom in (by clicking and dragging the cursor in the pane) for a more granular view. Click Zoom Out to expand time window or click:

to shift time window forwards.
to shift time window backwards.

Click associated with the chart to view information about the graph. Click to display the Customize Active Charts window. You can select charts to display and remove from the Available and Selected lists in the Customize Active Charts window. You can view up to 6 charts at a time in the page.

Use the following table when selecting the charts to view in the page. In the following table, the Charts column lists the charts that are available and the Metric column describes that type of metric that can be visualized in the chart:

Metric	Charts

^* This metric is diplayed in the default chart view for a node.

^** This metric is diplayed in the default chart view for a node and in the default list view for a table.

^*** This metric is diplayed in the default list view for a table.
