the 7 secrets of performance management in virtualized environments
DESCRIPTION
Whether you virtualize desktops or critical business applications, the dynamics and complexities of virtualized environments can cause significant performance and user experience issues that can diminish the benefits of virtualization and risk interruption of critical business processes. The toughest performance problems are the ones where users call and complain that "my application is slow". IT administrators often struggle to determine the root-cause of the problem and restore service levels: Is it the application server? The virtualization layer? Is it the network? Database? Storage ...? Join our live webinar with virtualization experts Dave Bartoletti (Forrester Research) and Srinivas Ramanathan (eG Innovations), and find out how to deliver: • Reliable performance assurance and user satisfaction • Complete performance visibility across your virtualized environment • Automatic, rapid root cause diagnosis for even the most complex performance problems • Pre-emptive problem detection and alerting before users call • Rapid ROI through right-sizing and optimizationTRANSCRIPT

Busting the Myths
1. Virtualization makes performance management easier.
2. Resource reservation ensures that VMs don’t interfere with each other.
3. The hypervisor view of virtual machines is sufficient to manage a virtual infrastructure.
4. Virtualization platforms already include all tools and metrics needed to manage the virtual layer.
5. Virtualization is just another silo that can be managed independently from other tiers.
6. Scaling is linear - more hardware means more performance.
7. VDI performance can be managed using tools that support Virtual Servers.

7 Secrets of Performance Management in a Virtual Infrastructure
Srinivas RamanathanCEO & Founder eG [email protected]
© eG Innovations, Inc | www.eginnovations.com
Myth #1: Virtualization makes performance management easier
Physical Virtual
Performance management is more important with virtualization
© eG Innovations, Inc | www.eginnovations.com
Myth #1: Virtualization makes performance management easier
Scope for performance management remains the same 10 servers, 30 guests => 300 virtual machines to monitor
New elements and features that need to be managed Hypervisor, datastores, LUNs, resource pools, cluster, DRS, vMotion,
snapshots, vSwitches, … Higher complexity because of resource sharing across VMs
VMs share CPU, memory, disk, network resources A single malfunctioning application in a VM can impact performance of
all other VMs
Performance management is more difficult with virtualization
© eG Innovations, Inc | www.eginnovations.com
Myth #2: Resource reservation ensures that VMs don’t interfere with each other
Resource reservation not always possible, or practical Defeats one of the big advantages of virtualization – resource
sharing
Resource sharing is a powerful concept, but …
© eG Innovations, Inc | www.eginnovations.com
Myth #3: The hypervisor view of virtualmachines is sufficient to manage VMs
• The Outside view shows the portion of physical resources used by each VM (CPU, disk, memory)
• Provided by the virtualization hypervisor
• Useful for capacity planning and identifying certain VM issues
• Does NOT show why a VM is consuming resources

Apps inside a VM
• The Inside view shows the portion of resources allocated to a VM that are used by each application and each user of the VM
• Provided by the guest OS (for Windows: WMI)
• Useful for user load balancing, identifying guest OS issues, misbehaving applications, and unauthorized user activities
• Does show why a VM is consuming resources, accelerates fix

The New Reality! Virtualization makes performance management more challenging.
Conventional management tools not sufficient to handle the new dependencies and dynamicity that virtualization introduces.
IT operations teams now need virtualization-aware, unified management solutions 360 degree visibility into every layer, every tier - networks, physical servers,
virtual machines, hypervisors, storage, applications Correlation across these diverse metrics to pin-point the root-cause
Management tools need to be domain-specific – VDI vs. virtual server

Virtualization-Aware Root-Cause Diagnosis
Response time metrics for the web-based service: ISG_WEB
Checkout and TransferBalances transactions have unusually high response times
Clicking on any of these transactions displays the service topology diagram for this web-based service

Virtualization-Aware Root-Cause Diagnosis
• Know which tier of a business service is impacted
The dependency arrows and color coding make it clear that a problem with the MS SQL Server is impacting the web server.
© eG Innovations, Inc | www.eginnovations.com
Virtualization-Aware Root-Cause Diagnosis• Know where the root-cause of a problem lies:
The SQL Server VM is hosted on an ESX Server, and something in the ESX Server itself is impacting the SQL Server VM.
Clicking on this icon brings up the layer model for the ESX server.
© eG Innovations, Inc | www.eginnovations.com
Virtualization-Aware Root-Cause Diagnosis
Something is wrong with CPU usage of the ESX console.
The ESX console is taking up close to 50% of the server’s physical CPU, which is very unusual !
• Know which layer is impacted – Network? System? Application?
The problem is at the OS layer.
Clicking on the diagnosis button lets us find out why.

Virtualization-Aware Root-Cause DiagnosisList of the top 10 CPU processes running on the vSphere/ESX service console
A Samba backup job is using almost 95% of the ESX console’s virtual CPU !
This is the root-cause of the web response time issues !

Virtualization-Aware Root-Cause DiagnosisWithout root-cause diagnosis, you have no idea where the problem lies
The root-cause of the problem
The effects of the problem
Simply clicking on this diagnosis button shows the root-cause of the problem: the Samba issue shown in the previous slide
All the problems appear to be equally important.
With root-cause diagnosis, you have a clear idea of what to do to resolve the problem.
