Performance problems often occur with no real warning– Many times end users are the first to notice problems– Root cause determination is difficult and time-consuming– Solving problems requires all-hands-on-deck bridge calls
Real-time understanding of performance is lacking– No reliable understanding of the health of IT infrastructure makes IT too reactive– Siloed monitoring tools do not allow a common “truth”– No correlation across IT silos
Optimizing IT infrastructure is difficult if not impossible– Understanding the abnormal metric behaviors that lead to degradation of Key
Performance Indicators is not possible with current tools– Understanding the abnormal behaviors that define your worst performing devices is
not possible with current tools– Heavy reliance on “Tribal Knowledge” of a few application experts
Management Challenges

What If You Could…
• Automate • Eliminate time-consuming problem resolution processes
• Correlate and Accelerate • “One Click” to root cause of emerging performance problems to reduce MTTI/MTTR
• Get Proactive• Avert end user and business impact of building performance problems
• Collaborate• Aggregate and correlate data from monitoring landscape to create a single “truth”
• Optimize• Tune components to deliver optimal performance for application transactions

vCenter Operation – Standard Edition
![Page 12: vCenter Operations](https://reader035.vdocument.in/reader035/viewer/2022062501/5681677a550346895ddc7ad5/html5/thumbnails/12.jpg)
Demo
• Familiarisation of UI• Infrastructure and Analysis
• Concepts• Workload• Health• Capacity
![Page 13: vCenter Operations](https://reader035.vdocument.in/reader035/viewer/2022062501/5681677a550346895ddc7ad5/html5/thumbnails/13.jpg)
vCenter Environment - Workload
• Workload Measures• Demand for resources vs. Resources currently used• Result is a percentage of Workload
• Low number is Good – Object has the resources it needs• Can go above 100% - Object is “Starving”
• Workload summarized across critical resources • CPU• Storage• Network• Memory
• Workload Details View• View the state of the Peer and Parent Objects and troubleshoot
• Am I a victim or a villain? • Is this a population problem?
![Page 14: vCenter Operations](https://reader035.vdocument.in/reader035/viewer/2022062501/5681677a550346895ddc7ad5/html5/thumbnails/14.jpg)
vCenter Environment - Health
• Health Measures• How normal is this object behaving: • 0-100 (Higher is Healthier or Normal)• Learns dynamic ranges of “Normal” for each metric• Learns patterns of behavior and identifies metric
abnormalities• Healthy = no abnormalities
• Health and Workload together• Health High and Workload High – Normal Behavior for
this timeframe• Health High and Workload Low – Normal Behavior for
this timeframe• Health Low and Workload High – Something is amiss!
Perfomance spike• Health Low and Workload Low – Something is amiss.
Demand drops
Important NoteLow Health does not
imply a problem. It tells you that the object is acting differently than normal.
![Page 15: vCenter Operations](https://reader035.vdocument.in/reader035/viewer/2022062501/5681677a550346895ddc7ad5/html5/thumbnails/15.jpg)
Learn Normal Behavior and Identify Abnormalities
• Doesn’t assume IT data has a normal bell-shaped distribution
• Sophisticated Analytics – 8 different algorithms
• Learns your dynamic ranges of “Normal” without templates
• Learns patterns of behavior and identifies Abnormalities

Health (Deviation)
• Green square: 76–100. • The health of the object is normal. No attention required.
• Yellow square: 51–75. • The object is experiencing some level of issues. You must check and take appropriate
action.
• Orange square: 26–50. • The object might have serious issues. You must check and take appropriate action as
soon as possible.
• Red square: 0–25. • The object is either not functioning properly or will stop functioning soon. You must take
an action immediately.
• Blue square: • No data is available for any of the metrics for the time period.
• Gray square: • The object is offline.
![Page 18: vCenter Operations](https://reader035.vdocument.in/reader035/viewer/2022062501/5681677a550346895ddc7ad5/html5/thumbnails/18.jpg)
Workload
• Green circle: 0- 84. • There is no excessive workload
on the object. No attention required.
• Yellow circle: 85–94. • The object is experiencing some
high resource workloads.
• Orange circle: 95–99. • Workload on the object is
approaching its capacity in at least one area.

Storage
• Since all the datastores are on the same array, how do we quickly tell the relative workload generated by every one of them?
• For each of these datastores, how do we know the relative workload generated by the VM?
• For every VM, how do we know the latency is within reasonable number?
• How do we show all the above data in “one chart”, without the need to show a lot of numbers?

vCenter Operations Standard Architecture
Four Main Services: Collector, Analytics, Web, ActiveMQ
Bundled DB: PostgresSQL DB File-based DB
(FSDB) for raw metric storage
Single Collector for vCenter. Embedded in appliance
![Page 36: vCenter Operations](https://reader035.vdocument.in/reader035/viewer/2022062501/5681677a550346895ddc7ad5/html5/thumbnails/36.jpg)
vCenter Operations Standard Processing
2a: Analytics runs daily to determine hour-by-hour Dynamic Thresholds for
next 24 hours
2b: Full FSDB is scanned by the analytic algorithms to determine per metric best match the next 24
hour period
1a: vCenter Collector collects metrics, topology & change
events from vCenter - Ongoing -
1b: Data stored in
FSDB
3: Incoming data points are tested against Dynamic
Threshold bands and used to calculate Health,
Workload and Capacity
2c: Store metric Dynamic
Thresholds data in PostgresSQL DB
4: Results provided to UI: Update
“Badges”, provide Root Cause for
Health scores, etc.

Dynamic Threshold Algorithms
Understand the normal behavior of any time-series metric
Eight (8) distinct algorithms each determine an upper and lower ‘band’ – results of each algorithm compete to ‘win’ to represent the ‘best choice’
vC Ops Ent - Stand Alone detects metric-level abnormalities for use in:
Dynamic Thresholds are the Cornerstone to all other forms of vC Ops Ent - Stand Alone Analytics

Smart Alert Trigger
vC Ops Ent - Stand Alone tracks aggregate amount of abnormality and alerts when “explosion” is detected, or when a ‘high water mark’ is detected
Intrinsically observed that performance problems are first seen at the metric level when metrics begin to behave abnormally
• Blue shaded region represents the number of metrics for an application (represented by a set of servers/devices) that are at any given time measured abnormally
• The Red line represents an Analytically determined ever-changing level at which vC Ops Ent - Stand Alone determines a performance warning is warranted – a Smart Alert is triggered

Health Score
Automatically understand performance ‘Health’ for
• 100 (Green) = Perfect Performance (i.e., entirely normal); • 0 (Red) = Terrible Performance (extremely abnormal behavior)
A single Server, Device, Resource
Entire Tier or Silo
Entire Application or Service
Entire Datacenter
Any Arbitrary Group of Resources
Objective measure of performance based on underlying level of abnormal behavior. Adjusted based on:
# of Abnormally behaving KPI
# of Abnormally behaving metrics
Consideration of lowest / highest
volume of abnormalities
