How many different virtualization management tools do you use to manage virtual resources?

Source: Forrsights Hardware survey, Q3 2011;Q3 2012

Consolidate your management tools – no more silos

51% use more than one more than one management tool

The Forrester APM Reference Model


Yesterday: Build performance monitoring silos


Today: Unified performance management platform



MTTI

The objective: Reduce mean time to resolution

› Mean time to identify

› Mean time to know

› Mean time to fix

› Mean time to verify

Mean time to resolution is a good Operations KPI

MTTK MTTF MTTV

MTTR

HERE is the opportunity!

Reduce Waste by Attacking MTTK


The benefits of a unified APM strategy

› Lower frequency of services outages

› Shorter length of service outages

› Higher IT operations efficiency

› Greater user acceptance

› Lower cost of IT operations


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]


Myth #1: Virtualization makes performance management easier

Physical Virtual

Performance management is more important with virtualization


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


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 …


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

A problem in one tier can affect all the other tiers. Is it the network, database, app server, or virtualization tier?

Myth #5: Virtualization is just another silo that can be managed independent of other tiers

Excessive disk reads by the one VM slows down application within another VM

A problem in the virtualization tier can impact all the applications it supports. Monitoring systems need to be “virtualization-aware”.

Myth #6: Scaling is linear, more hardware means more performance

It is critical to understand the overall performance at all levels and identify the bottlenecks


Myth #7: VDI performance management can be done using tools that support Virtual Servers

Support Systems

VDIManagement focus should be:

Beyond the virtualization tier

On users, not VMs On the desktop

Performance management for VDI is extremely unique as you need a solution that combines multiple

different performance management methodologies


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

Live Solution Tour


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



• 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.


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.



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.
