Using esxtop to identify storage performance issues in ESX/ESXi

Today we have a new vSphere video that demonstrates how to use esxtop to identify storage performance issues in a vSphere ESX / ESXi environment.

The esxtop utility and the latency statistics that it provides are very useful when troubleshooting performance issues with SAN-connected storage. Watch our latest video and learn!

For additional information see VMware Knowledge Base article Using esxtop to identify storage performance issues for ESX / ESXi (multiple versions) (1008205).

Uploading diagnostic information for VMware through the Secure FTP portal

VMware recently launched the new VMWARE Secure Data Transfer portal which offers the ability to upload diagnostic information and files to VMware in a safe and secure way.

To address a Support Request, VMware Technical Support may request diagnostic information from the affected VMware products. Our video today provides a demonstration of the procedures necessary to upload diagnostic information to VMware using the Secure FTP (sftpsite.vmware.com) portal.

Uploading diagnostic information to VMware using the Secure FTP portal includes these methods:

  • Using your web browser and the HTML Interface
  • Using your web browser and the Java Applet
  • Using the command-line from a Linux operating system
  • Using third-party clients

Notes

  • Internet Explorer 9 and above is supported.
  • Other supported browsers include Firefox, Chrome, and Safari.
  • When uploading with Internet Explorer 10/11, you may have to switch to compatibility mode.
  • Do not use the HTML interface to upload files larger than 2 GB.

This video is based on VMware Knowledge Base article Uploading diagnostic information for VMware through the Secure FTP portal (2069559).

Manually collecting diagnostic logs from the Android VMware switch

In today’s new video tutorial, we discuss and demonstrate the process for manually collecting diagnostic logs from the Android VMware Switch.

The normal method to collect the logs from a VMware Ready device is using the VMware Horizon Mobile Server console or through the Horizon Workspace console to which the device is connected. However, if the device fails to connect to the server, you may have to collect the logs from the device itself.

This video provides steps to collect the logs from a VMware Ready device on which the VMware Switch application is installed when other methods are not applicable.

For additional information, see VMware Knowledge Base article Manually collecting diagnostic logs from the Android VMware Switch (2058741).

Troubleshooting virtual machine performance issues

Here is our third Support Insider Live video episode with tips straight from the mouths of our front-line Technical Support Engineers.

Our video today features Sajjad Siddicky talking about his go-to tools for troubleshooting performance issues with virtual machines. Performance of our vms is something we are all concerned with, but where does one start?

Check out this two minute video:

Sajjad recently wrote a piece about VisualEsxtop you can read here. VisualEsxtop is an enhanced version of resxtop and esxtop.

Additional information relating to virtual machine performance issues can be found in KB article: Troubleshooting ESX/ESXi virtual machine performance issues (2001003).

Read more about our new Support Insider Live video series here.

Troubleshooting wiki

We recently ran a survey that sampled customers who opened support requests with us, and one of the questions asked if you would be interested in a new troubleshooting wiki to supplement our other self-help resources. The results are in and we are now discussing.

This got us thinking… perhaps that question needs to be refined. Are you responding to the troubleshooting aspect of the question, or are you responding about the prospects of a wiki?

Whenever we post something here on The Support Insider that indicates it is a troubleshooting tool, we see a lot of interest. Customers like you want to be able to quickly deal issues you encounter, and VMware approved tools or methods are very popular. For instance, our Resolution Path KB articles. We know you’re very interested in anything new we can produce in this area, and a wiki is just one approach. We want to consider all options and use the best tool for the job.

In our next survey, we’ll be sure to be a bit more specific in asking what it is you’d like to see. Maybe you’d like to tell us in the comments below what you’d like most from us?

Protip: When we post a blog topic here that touches on troubleshooting, we tag it. You can view all of our troubleshooting related posts using this URL: http://blogs.vmware.com/kb/tag/troubleshooting. You can use the same URL construct for any of the tags we use in our posts (listed right underneath every post), for example: http://blogs.vmware.com/kb/tag/sso

Collecting diagnostic information from vSphere using the vSphere Web Client

When working with VMware Technical Support you will routinely be asked to provide diagnostic log bundles from your vSphere environment.  Our technical support staff use these in their investigation of your reported issues and in some instances to determine root cause.

We have a new video today which discusses and demonstrates how you can use the vSphere Web Client to collect the diagnostic information for the ESXi and vCenter Server systems, which run in your vSphere 5.1 environment.

This video is specifically geared towards users of our vSphere 5.1 product suite.

In this tutorial you will be guided through the necessary steps for gathering the log bundles from your vSphere 5.1 systems using the vSphere Web Client.

When the vSphere Web Client is connected to the vCenter Server system, you can select hosts from which to generate and download system log files and the option to include vCenter Server and vSphere Web client logs.

For additional information, see VMware Knowledge Base article Collecting diagnostic information for ESX/ESXi hosts and vCenter Server using the vSphere Web Client (2032892).

Note: For best viewing results, ensure that you have the 720p setting selected and that you are viewing using the full screen mode.
