Auto Refresh (Every 5 Seconds) | Automatically refresh all trend charts every 5 seconds — useful for monitoring active workloads in real time. |
Linkage Chart | Synchronize chart cursors so you can see the values of different metrics at the same point in time, making it easier to correlate anomalies across metrics. |
Chart Layout | Set the number of trend charts displayed per row. |
Add Instances and Metrics | Add or change the instances and metrics shown in the dashboard. |
Details (in a trend chart) | Expand the chart and adjust the time range for a closer look at a specific metric. |
