Siloed organizations result in the “It’s not me!” syndrome

The Real Cost of Silo Monitoring

Each MOT (moment of truth is also a silo) is indicated by a red box – The more silos you have, the more time it takes to manually triage a problem.

Time is money…!

Save Time – Save Money

As illustrated in the two figures, 14 interactions vs. 3 interactions – Before automation vs. after automation.

VDI Service Monitoring eliminatesfinger pointing!

Independent monitoring ofindividual applications

Status of network elements, bandwidth utilization, etc.

Holistic view of the end user service

eG’s Key Differentiators Monitoring VDI Environments

April 14, 2023

VDI Monitoring Needs

• Total end to end visibility into your VDI environment Which users are logged in? What applications are they

accessing? Who are the resource intensive users? What latencies are they seeing? Is user load balanced across the servers?

• Ability to quickly pin-point where the bottlenecks are Network? Server? VM? Broker? Application? Disk? Contention among guests for needed resources?

• Flexible management reporting C-level reports Usage reports Capacity planning / optimization reports Collection of chargeback metrics

• Should be easy to deploy, excellent ROI Out-of-the-box capabilities Little customization needed Minutes to install, fine-tune in hours Don’t need experts to use the technology

VDI Monitoring Challenges

Disk reads

MS AccessOutlook , Word Processing

Excessive disk reads by the user running MS Access slows down accesses for the user running Outlook & Word processing

Multi-tier infrastructures are difficult to manage.

Adding VMs to the mix makes the problem even harder!!!

VDI Monitoring Challenges

• Not feasible to deploy an agent per OS / VM

Higher deployment overhead, time-consuming

Higher licensing cost

Higher resource consumption

• Different requirements for monitoring application server and virtual desktops

Application servers hosted on VMware

Desktops hosted on VMware

Few VMs (<10) per ESX server 30-40 VMs per ESX server

VMs mostly powered on all the time

VMs powered on/off dynamically

In-depth application monitoring required (Citrix, Oracle, etc.)

Monitor user activity, access patterns


The eG Monitor for VDI InfrastructuresTM

Patent Pending In-N-Out MonitoringTM with Automated Correlation - Monitor the outside (server metrics)

- Monitor the inside (desktop and app metrics)


Monitoring Virtual Desktops with eG

• Layer Model

• Drill down view into different aspects of the VDI system

List of users logged on to virtual desktops

Details of resource usage foreach user desktop session


• Individual Desktop view

• Inside Monitor - Drill down view of a Guest Desktop



• Process detail inside view of a Guest Desktop


Comparing Performance Across VMs


Virtual Desktop Monitoring

• How many desktops are powered on simultaneously on the ESX Server?

• Which users are logged on and when did each user login?

• How much CPU, memory, disk and network resources is each desktop taking?

• What is the typical duration of a user session?

• Who has the peak usage times?

• What applications are running on each desktop?

VMotion Monitoring

• Which ESX Server is a virtual guest running on?

• When was a guest moved from an ESX Server?

• Which ESX Server was the guest moved to?

• Why was the guest migrated? What activities on the ESX host caused the migration?

What the eG VM MonitorTM

Reveals

Case Study

Target Environment & ObjectivesScope

• A VDI environment with 750 Desktops.

Objectives

• Total visibility into their VDI infrastructure

• Users were constantly complaining of performance issues and fingers were being pointed at the virtualization group, the customer wanted to get the right information on where the issues were.

• Compare demand on the infrastructure to resource consumption

• Automatic Baselining of Key Performance Measurements – The ability to learn the norm of an environment automatically based on the data collected over a period of time.

• Capacity Planning Reports

• Pro-actively isolate and alert on issues within desktops.

VDI Latency

The average network latency experienced by user desktops hosted on the ESX servers is between 0.01 and 0.05 secs.

ESX – CPU Utilization

We can see different Virtual Guests executing on ESX server SCD2VMH516 have reported of High Ready % - This could mean that there might be an CPU bottleneck caused by some process on the Console OS or could be an application on the Virtual Machines taking too many CPU Cycles to execute…

Load Balancing in the VDI Farm

There are between 28 and 30 registered Guests per VDI server.

ESX – VDI User Load ReportThe ESX VDI servers with Maximum number of users (26) are SCD2VMH512,SCH2VMH513 SCH2VMH517 and SCH2VMH200.

Even though there are around 28 registered guests, There are few servers with very less number of users namely SELGVMH202, SNRMVH201 and SSPRVMH201

VDI Servers Memory Utilization

Each of the 25 ESX servers have more than 16 GB of Memory allocated to them.

This chart shows the Non-Kernel Memory usage of the ESX servers. Non-Kernel Memory is the that part of Memory allocated to Virtual Guests.

This chart shows the Free Memory available at the ESX Host level after allocating resources to all the Virtual Machines. We can see that the SCD2VMH ESX servers have lower free memory when compared to the rest of the servers.

Identifying Resource Hogs

The user colvtw is seen taking nearly 100% CPU for 30 minutes on Virtual Machine VFREVM1025. This virtual Machine is part of ESX server SFREVMH202

Identifying Resource Hogs

The user colvtw is accessing MSACCESS application on Virtual Machine VFREVM1025 which is consuming nearly 100% CPU on the Virtual Machine.

Common Console for All Access Technologies


The Value Proposition of the eG VDI Monitor

In-N-Out Monitoring gives unique view of server- and user-focused activity & resources Proactively detect and correct problems before users notice Increase revenues by reducing mean time to repair Efficient use of operations staff

eG Enterprise Manager

Case Study - Summary

• eG Enterprise was implemented in one afternoon.

• eG was able to identify configuration issues that helped the customer prevent potential scalability and performance issues.

• eG provided end-to-end visibility into the target infrastructure that enabled the customer to keep track of all their important service level parameters.

• eG was routinely able to isolate issues that could potentially affect the entire environment and pro-actively identify the root cause. This helped the customer to focus on where the real issues where and fix them and saved the virtualization team from being unnecessarily blamed.

• eG helped the customer understand the demand on the target infrastructure and the amount of hardware resources consumed to service that demand.

• eG provided an in-depth view of each and every desktop that helped the customer teams to service the support calls effectively. The ability to provide this information without an agent on the client was important to the customer
