RDS Host is a member of the RDS Farm. This dashboard gives an overall performance of the RDS Host, with the ability to drill down and troubleshoot the host.

Design Consideration

This dashboard is designed to complement the RDS Farm Performance dashboard and has a similar design. It acts as the details dashboard, allowing you to drill down from a farm to one of its host members.

For a smaller environment, where you can manage directly at the host level, this dashboard is also designed as an entry point. You can directly navigate from the World level to the Host level, bypassing the RDS Farm.

How to Use the Dashboard

Review the RDS Hosts Performance Distribution bar chart.

  • Expect all of them to be in the green range. At the very least, none of them should be in the red.

  • Selecting one of the bars reveal the objects within the bucket. Click the Maximize button in the tool bar of the widget to clearly see the list. You cannot select one of the rows to drive other widget.

Review the table Pods.

  • Expect all of them to be in the green range. At the very least, none of them should be in the red.

  • Pay attention to the hosts that are not performing.

Select one of the entries in the table.

  • Its members, RDS Farms are shown in the table underneath.

Review the table RDS Farms and Hosts.

  • Expect all of them to be in the green range. At the very least, none of them should be in the red.

  • Observe the hosts that are not performing.

Select one of the entries in the table.

  • The KPI of the selected entry is shown in the scoreboards. There are five scoreboards showing different aspect of performance.

  • Its relevant property is shown in the property widget.

Select one or more entries in the scoreboard.

  • The line chart below the scoreboard plots the selected metrics.

  • Use the metric chart widget to compare metrics to see if there is any correlation.

  • You can also stack them. For example, you can combine Read IOPS and Write IOPS to get the Total IOPS. But, you should not combine Read Latency and Write Latency to get total latency as you must consider the read to write ratio.

Point to Note

You cannot drill down from RDS Host to its session, because there is no relationship. It has to be done at the RDS Farm level.
