Hey guys ! We are Friday, and I take advantage of this last day of the week to test some new products I heard about this week!

Today we will talk about DRS-Lens, product of the VMware labs by three contributors (Sai Inabattini, Vijayakumar Subbarayan and Vikas Madhusudana) !


What’s DRS-Lens ?

DRS Lens provides a simple, yet powerful interface to highlight the value proposition of vSphere DRS. Providing answers to simple questions about DRS will help quell many of the common concerns that users may have. DRS Lens provides different dashboards in the form of tabs for each cluster being monitored


With DRS-Lens you can monitor from 1h to 24h :

Cluster Balance

Provides a graph showing 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

There will be a chart showing a summary of total VMs in the cluster that are happy and those that are unhappy. Users can then select individual VMs to view performance metrics related to its happiness, like %CPU ready time, memory swapped, etc.



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 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.


How to install it ?

To install and try DRS-Lens, you can download the .ova package here

To deploy an .ova you can see my previous post here


You can now access to the interface by :

Have a nice week-end ! 🙂
