DRS Lens – A new UI dashboard for DRS

Follow

DRS Lens provides an alternative UI for a DRS enabled cluster. It gives a simple, yet powerful interface to monitor the cluster real time and provide useful analyses to the users. TheUI is comprised ofdifferent dashboards in the form of tabs for each cluster being monitored.

Cluster Balance

Dashboardshowing the variations in the cluster balance metric plotted over time with DRS runs. This shows how DRS reacts to and tries to clear cluster imbalance every time it runs.

VM Happiness

This dashboard shows VM happiness for the first time in a UI. This chart shows the summary of total VMs in the cluster that are happy and those that are unhappy based on the user defined thresholds. Users can then select individual VMs to view performance metrics related to its happiness, like CPU ready time and memory swapIn rate.

vMotions

This dashboard provides a summary of vMotions that happened in the cluster over time. For each DRS run period, there will be a breakdown of vMotions as DRS-initiated and user-initiated. This helps users see how actively DRS has been working to resolve cluster imbalance. It also helps to see if there are vMotions outside of DRS control, which may be affecting cluster balance.

Operations

This dashboard tracks different operations (tasks, in vCenter Server) that happened in the cluster, over time. Users can correlate information about tasks from this dashboard against DRS load balancing and its effects from the other dashboards.

Users can download DRS Lens from VMware flings website.
