19. “Inside View
of User Sessions“
(Monitor users not just Servers)
Best Practice #2

20. Provide – Real Time, in-depth, user session statistics with
Correlation and quick Search.
Benefit: Reduce service downtime; Keep users happy!
Inside View for Every User
Identify problems only
visible from within the user
session

21. “Pro-Active Monitoring”
(Prevention is better than cure)
Best Practice #3

22. Pro-Active Monitoring
A critical event
was raised when
Citrix server went
down

23. Prevent Outages
Benefit: Prevent problems from impacting users!
Proactive alert sent 30
mins before the
problem occurred –
alert pertained to
user’s memory usage

24. “Monitoring of Capacity
& Configuration Changes”
(Changes and Bottlenecks)
Best Practice #4

25. PERFORMANCE ALERTS
5. Correlating Performance and Configuration
Correlate performance with configuration changes
CONFIGURATION CHANGE
Benefit: Saves endless hours of troubleshooting
Track Configuration Changes

26. 6. Historical Reports on Users, Not VMs
Benefit: Know usage patterns, trends for effective capacity planning
Find out who the top users are
Understand Usage Patterns

27. 5. Correlating Performance and Configuration
Benefit: Right size your environment for better ROI
Find Your Bottlenecks

28. I/O issues – ESX Impact

29. I/O issues – Storage Bottleneck
Benefit: Right size your environment for better ROI

31. Best Practice Approach
1. Total Performance Visibility – Complete, end-to-end
service view with performance correlation
2. Inside View of User Sessions – In-depth visibility with
In-N-Out Monitoring inside each user’s desktop
session
3. Pro-Active Monitoring – Auto-baseline and end-to-
end correlation to fix performance problems before
users get impacted
4. Monitoring of Capacity and Configuration Changes –
Right-size your environment for maximum ROI and
weed out changes that cause performance issues

35. PVS Write-Cache Storage Options
 Most use shared SAN/NAS storage
 Local disk has limited IOPS and is difficult
to maintain
 Local SSDs fail with write-heavy
workloads
 PVS servers will become a storage or
network bottleneck
 RAM has limited capacity

36. Where are the XenApp deployment risks?
 Under-sizing of the PVS write-cache
 SAN/NAS introducing storage network risk
The impact:
 Cost overruns – can be very significant
 Project delays – while infrastructure is resized
 Unhappy users and management – CFO, CIO, CEO, etc.
… leads to risk aversion and very cautious approach to project

37. Atlantis ILIO for Citrix XenApp
 Performance
– Accelerates boot/logon, provisioning, application
response time
 Storage Savings – 100%, No Storage!
– No shared storage, local disk or SSDs required
