-# How to chart performance with VM insights
+# Chart performance with VM insights
 
-VM insights includes a set of performance charts that target several key performance indicators (KPIs) to help you determine how well a virtual machine is performing. The charts show resource utilization over a period of time so you can identify bottlenecks, anomalies, or switch to a perspective listing each machine to view resource utilization based on the metric selected. While there are numerous elements to consider when dealing with performance, VM insights monitors key operating system performance indicators related to processor, memory, network adapter, and disk utilization. Performance complements the health monitoring feature and helps expose issues that indicate a possible system component failure, support tuning and optimization to achieve efficiency, or support capacity planning.

+VM insights monitors key operating system performance indicators related to processor, memory, network adapter, and disk utilization. Performance complements the health monitoring feature and helps to:
+
+- Expose issues that indicate a possible system component failure.
+- Support tuning and optimization to achieve efficiency.
+- Support capacity planning.
 
 ## Limitations
-Following are limitations in performance collection with VM insights.
+Limitations in performance collection with VM insights:
 
-- **Available memory** is not available in all Linux versions including Red Hat Linux (RHEL) 6 and CentOS 6. It will be available in Linux versions that use [kernel version 3.14](http://www.man7.org/linux/man-pages/man1/free.1.html) or higher. It may be available in some kernel versions between 3.0 and 3.14.
-- Metrics are only available for data disks on Linux virtual machines using XFS filesystem or EXT filesystem family (EXT2, EXT3, EXT4).

 ## Multi-VM perspective from Azure Monitor
 
-From Azure Monitor, the Performance feature provides a view of all monitored VMs deployed across workgroups in your subscriptions or in your environment. To access from Azure Monitor, perform the following steps.

-On the **Top N Charts** tab, if you have more than one Log Analytics workspace, choose the workspace enabled with the solution from the **Workspace** selector at the top of the page. The **Group** selector will return subscriptions, resource groups, [computer groups](../logs/computer-groups.md), and virtual machine scale sets of computers related to the selected workspace that you can use to further filter results presented in the charts on this page and across the other pages. Your selection only applies to the Performance feature and does not carry over to Health or Map.
