Myths
– vCenter Operations Manager is only for the Enterprise with thousands
of virtual machines
– I am a vSphere Ninja – esxtop is the only tool I need. vCops got
nothing on me
5
Overview ‒ Features
– How much capacity have I left in my environment – when will I run out
of resources and what resource (storage, cpu, memory, network)
– Reclaim waste
– Proactive alerting
– Root Cause analysis
– Deep forensics analysis
– vCenter Operations Manager is a lot more than badges and it is a lot
more than we can cover in 50 minutes!
6
Why Badges?
9
- vSphere has several hundreds counters per object
- Translate all of these numbers into Badges. Makes it easier to troubleshoot
without being a vSphere Expert
- If a Badge changes color figure out why and fix it
vCenter Alarms versus vCops Smart Alerts
– vCenter uses static thresholds
– vCops uses dynamic thresholds
– Each object has its own thresholds calculated
13
Virtual Machine CPU Usage Alarm in vCenter
14
Warning
5 min > 75%
Alert
5 min > 90%
How often does
this actually report
a fault?
Dynamic Threshold in vCops
15
- Instead of static thresholds vCops uses dynamic thresholds (DT)
- No need to get alert if a machine is doing what it normally does
- How do we know normal behaviour is good behaviour??

What About Performance Graphs and ESXTOP?
20
- They are still relevant
- Use the right tool for the job
- These tools are complementary. All have their strenghts and weaknesses
ESXTOP vs. Perf. Graphs vs. Metric Chart
– Use ESXTOP for ”live” monitoring
– Use vCenter Performance Graphs for ”real-time” (past-hour)
– Use vCops Metric Chart for everything that is not ”real-time”
– Trendline, Dynamic Thresholds, Multiple Graph on one page. All counters
available, 5 minutes intervals.

Finding the Most IO Intensive Virtual Machines
- Users have reported slow disk performance
- You want to find out what virtual machines is saturating the storage array.
- You have 30 ESXi hosts, 40 datastores and 600 virtual machines.
Approximately 15 VMs per datastore.
- What do you do?
22
– Start 30 ESXTOP in batch mode and add all data to Excel?
– Open 600 Performance Graphs in vCenter and save them all?
– All of the data is in the vCenter Database, but not easily accessible!
– With vCops it is extremely easy to find this information.
The Key word is ”Heat Maps”
23
Finding the Most IO Intensive Virtual Machines
vCops Heat Maps
– A Heat Map is a graphical representation of one or two metrics.
– Use them to find ”Hot-Spots” in your environment
– One Metric defines the Size of the blocks in the map
– The second metric defines the Color of the blocks in the map
– Build your own or use the pre-defined
24
Build You Own Heat Map of Use the Pre-defined
25
- Build your own heat map
- Color by Read Latency and Size by Commands Per Second
Custom Dashboards
- The Option to build your own views of the infrastructure
- Drag and drop
- Widgets
- Heat Maps
- Metric Graph
27
Why Customizable Dashboards
– Create different views of the infrastructure
– Storage View
– Network View
– vSphere View
– CPU analysis
– Memory analysis
– Datastore analysis
– My favorite: Forensics dashboard
28
Summary
– Use vCenter Operations Manager Metric Chart for insight into every
counter. No rollup
– Use the Badges in your troubleshooting methodology
– Use Smart Alerts to find out if the object is behaving normal
– Use Heat Maps to find hotspots
– Build your own views of your infrastructure with Custom Dashboards
