Badges – Health

Answers complex questions like:• How is the entire virtual data center doing?

• For every cluster, host, datastore, what’s their health?

Health is the current operational state• It represents what is wrong now and should be

addressed within 1 day. Thus Health needs to be scored

such that if it’s red, then it really needs attention.

Weather Map

• Simple way to check that entire farm is healthy

• Shows health of all parent and child objects

• Each square can be VM, ESX, datastore, cluster datacenter,

vCenter

Value Explanation

75 – 100 Normal behaviour

50 – 75 The object experience some problems.

25 – 50 The object might have serious problems. Check, and take action as soon as possible

0 – 25 The object is either not functioning properly or will stop functioning soon

CONFIDENTIAL 60

Badges – Workload Answers complex questions like:• For every object how is Demand vs Spply?

• For every single VM, is CPU/Memory/Disk/Network

bound?

• Any VM is not getting what they are entitled/required?

• What’s the normal workload range for every object in

our vDC?

Workload is not utilisation or usage

• More accurate than utilisation as it takes many factors

than just utilisation

Workload = (Demand/Entitlement)

• Entitlement is dynamic. Affected by shares, limit, etc.

• Demand ≠ Usage

• Usage may mean passive usage (RAM page is there but no

write/read at all

• Score is Max(CPU, RAM, Disk IO, Net IO)

Value Explanation

0 – 80 Workload is not high.

80 – 90 The object is experiencing somehigh resource workloads.

90 – 95 Workload on the object isapproaching its capacity in ≥1 areas.

>95 Workload on the object is at or over its capacity in ≥1 areas.

CONFIDENTIAL 61

Badges – Anomalies Answers complex questions like:• Is our vDC doing as usual? Are there any unexpected

changes (as we have dynamic environment)?

• Which VMs, ESX, cluster, datastore etc are behaving

abnormally?

• … and exactly which counters are the culprits?

Identifying metric abnormalities

• It needs to learn dynamic ranges of “Normal” for each

metric, so give it >3 cycle per metric

• A month-end job means it needs 3 months

• Normal range changes after configuration or application

changes

Anomalies score

• High number of anomalies:

• Usually an indication of problem

• Demand change

• Application team changed code/app

• KPI (Key performance Indicator) metrics impacts the

anomalies more than non KPI metrics

Value Explanation

0 – 50 Normal Anomaly range

50 – 75 The score exceeds the normal range.

75 – 90 The score is very high.

> 90Most of the metrics are beyond their thresholds. This object might not be working properly or will stop working soon.

CONFIDENTIAL 62

Badges – Faults Answers complex questions like:• What fault do we experience in our vDC?

• For every object, what faults does it have?

Specific knowledge of which vCenter events

• Which events affect Availability and Performance of

which object?

• Pulled from active vCenter events

• Example:

• Loss of redundancy in NICs or HBAs

• Memory checksum errors

• HA failover problems.

• Each fault has a default score

• Highest individual Fault Score drives the Fault object

score

Best Practices

• Do not change Fault Threshold

• Use Alerts View to manage Faults. You can Filter it to

just show Faults.

Value Explanation

0 – 25 No fault is registered on the object

25 – 50 Faults of low importance happens on object.

50 – 75 Faults of high importance happens on object.

> 75 Faults of critical importance happens on object

CONFIDENTIAL 63

Badges – Risk Answers complex questions like:• Do we have risk from performance or capacity in our

vDC? If yes, where are they and how serious?

• Which objects are at risk? What is the specific risk?

Risk Score takes into account

• Time Remaining

• Capacity Remaining

• Stress

Risk is an early warning system

• Identifies potential problems that could eventually hurt

the performance

• The Risk Chart shows Risk score over the last 7 days,

giving a view of trend

Value Explanation

0 – 50 No problems are expected in the future.

50 – 75 There is a low chance of future problems or a potential problem might occur in the far future.

75 – 100 There is a chance of a more serious problem or a problem might occur in the medium-term future.

100 The chances of a serious future problem are high or a problem might occur in the near future

CONFIDENTIAL 64

Badges – Time remaining Answer complex questions like:• How much time do we have before we need to buy

more server, storage, network before performance

starts to degrade or we run out of capacity?

• For every cluster, VM, datastore, how much time do we

have?

Measures time remaining before each

resource type reaches its capacity• CPU

• Memory

• Disk (IOPS & Space)

• Network I/O

Early warning of upcoming provisioning

needs• Based on Score Provisioning buffer. Default value is 30

days.

• Set in “Capacity & Time Remaining” section

Value Time remaining

50 – 100 > 2x SP Buffer (60 days)

25 – 50 < 2x SP Buffer

<25 Near SP Buffer

0 < SP buffer (30 days)

CONFIDENTIAL 65

Badges – Capacity remaining Answer complex questions like:• How many more VM can we put without impacting

performance or using up capacity?

• For every cluster, VM, datastore, which components (CPU,

RAM, Disk, Network) would run out first?

Early warning system• A low score of 1 mean you still have >30 days.

• Measures how many more VMs can be placed on the

object

Percentage of Total VM “Slots” Remaining• Based on the average size of the VM on the object (e.g.

VM profile)

• Each object has its OWN VM profile size: Host, Cluster,

Datacenter, Etc.

From the table, notice value is not linear

• It is also not the same with Time Remaining threshold.

• A value of 30 means >120 days for capacity but around 40

days for time.

Value Capacity remaining

>10 >120 days

5 – 10 60 – 120 days

2 – 5 30 – 60 days

1 <30 days

CONFIDENTIAL 66

Capacity remaining calculation Determine capacity constraint resources

Deployed or Powered On VMs• Powered off VMs only use disk space resources

• Powered off VMs use ALL of the 4 resources

Calculation example:

• The limit is 40 more VMs

• We have 9 deployed VMs

• 40/(40+9) = 81%

You can drill down to see details

• You can check all 9 components as shown on right

• This helps to answer the question which components have

how many days or VM left

• Summary = min (all 9 components)

CONFIDENTIAL 67

Badges – Stress Answer complex questions like:

• In our vDC, do we have stress points or periods? How bad is it?

• For every cluster, VM, datastore, which ones are experiencing

stress and how bad is it?

Measures long-term or chronic workload (6

weeks)

• Chart shows weeks break down of Stress for each day/hour

averaged over the last 6 Weeks

• Workloads > 70% = “Stressed”

• Threshold Configurable as per screenshot below Value Explanation

0 – 1 Normal score. No action needed

1 – 5 Some of the object resources arenot enough to meet the demands.

5 – 30 The object is experiencing regular resource shortage.

>30Most of the resources on the object are constantly insufficient. The object might stop functioning properly.

CONFIDENTIAL 68

Stress Calculation

Stress Score is a % and is based on area of Workload Above “Stress Line”

Threshold compared to the Total Capacity of the object• Stress Score = (Stress area / Stress Zone) *100

• But max value can be > 100% as the workload can be >100.

Example• Stress Line is 70% Workload

• 12% of the area is above the 70% threshold

• Stress Score is 12

CONFIDENTIAL 69

Badges – Efficiency Answer complex questions like:

• Are there optimization opportunities in our vDC?

• How well do we do in terms of VM provisioning? Do

we get them right?

Efficiency Score factors

• Reclaimable waste

• Density ratio

Graph Depicts VMs by Percent

• Optimal – Optimally Provisioned VMs

• Waste – Over Provisioned VMs

• Stress – Under Provisioned VMs

• Not used in Efficiency Calculation (see Risk)

Value Explanation

>25 The efficiency is good. The resource use on the selected object is optimal.

10 – 25 The efficiency is good, but can be improved. Some resources are not fully used.

0 – 10 The resources on the selected object are not used in the most optimal way.

0 The efficiency is bad. Many resources are wasted.

CONFIDENTIAL 70

Badges – Reclaimable waste Answer complex questions like:

• Do we over provisioned the VMs in terms of CPU, RAM and

Disk? If yes, what’s the degree of over provisioning?

• For every cluster, VM, datastore, what can we reclaim?

It identifies the amount of reclaimable

resources

• CPU

• Memory

• Disk

Reclaimable Waste = Reclaimable Capacity /

Deployed Capacity

• Waste Score = Max(CPU Waste Score, RAM Waste Score,

Disk Space Waste Score)

• Disk calculation can also include old snapshots and

templates

Value Explanation

0 – 50 No resources are wasted on theselected object.

50 – 75 Some resource can be used better.

75 – 100 Many resources are underused

100 Most of the resources on the selected object are wasted.

CONFIDENTIAL 71

Badges – Density Answer complex questions like:

• How high can we push our consolidation ratio before we experience performance problem?

• Now that’s a million dollar question!

• For every datacenter, cluster, ESXi, what are our key ratios and how much head room do we have?

Contrasts Actual vs Ideal Density

• Identify Optimal Resource Deployment Before Contention Occurs

• Ideal is based on demand, not simple

configuration.

• High Density is good. 100 is not too high.

Value Explanation

>25 Good consolidation

10 – 25 Some resources are not fully consolidated

0 – 10 The consolidation for many resources is low

0 The resource consolidation is extremely low.

CONFIDENTIAL 72

Using badges together

Workload High & Anomalies Low & Stress High

• Workload – Object is Running Hot. Potentially Starving

for Resources

• Anomalies – Normal Behavior for this timeframe

• Stress – Object is often running under high Workload.

Workload High & Anomalies Low & Stress Low


for Resources

• Anomalies – Normal Behavior for this timeframe

• Stress – Object usually has enough resources

Workload High & Anomalies High


for Resources

• Anomalies – Abnormal behavior for this timeframe

If there are Alert and Fault too, then it is a sign

of major issue

Add resources

Not likely a big problem…

a cyclical workload spike?

Something is a miss! Immediate attention.

Recommendations

Network Set 1Gbps physical adaptors to autonegotiation for optimum performance

NetworkChange the default port group security settings ForgedTransmits and MACAddressChange to Reject

NetworkAvoid mixing NICs with different speeds and duplex settings on the same uplink for a port group/dvportgroup

StorageSeparate the space allocations on shared datastores for templates and media/ISOs from virtual machines

CONFIDENTIAL 83

Recommendations

VirtualMachines

Set the memory reservation value for Java-based (JVM) virtual machines to the OS required memory plus the JVM heap size

VirtualDatacenter

Use vCenter Server roles, groups, and permissions to provide appropriate access and authorization for virtual infrastructure administration. Avoid using Windows built-in groups (Administrators)

VirtualMachines

Use as few vCPUs as possible. Do not use virtual SMP if application is single threaded and will not benefit from additional vCPUs

VirtualDatacenter

Set up a redundant service console port group to use a separate vmnic on a separate subnet for improved HA redundancy
