Forrester Research: What are your top three issues in managing corporate IT Infrastructure?

Consistent end-to-end application & service performance guarantees


Traditional Approaches Add to the ComplexityTraditional Monitoring approaches are very Silo based. A solution for each of the individual areas with none of the data correlated to get an understanding of the application delivery and how our users are experiencing it.

Key Take-aways


Where is the problem?To diagnose application delivery issues we need visibility into the areas of potential bottlenecks Historically, teams use different systems to monitor specific domains without knowledge transfer

• Is the problem on my Presentations Servers?• Are the Network requests from our applications experiencing large

amounts of delay or having socket connection issues?• Are my Users desktops performing poorly due to other

applications?

Application FaultsWhy is my application crashing?

Key Questions:• What was running prior to

the crash?• Were resources being

heavily consumed?• What was the fault context?• What DLL’s were loaded?• What other events were

occurring for the user?

Automated real-time crash collectionMoment in time analysisUser activity in applicationSystem resource consumptionLoaded DLL’s

Citrix EdgeSight

Requirement:To capture enough information about the crash to assist our developers and 3rd party vendors to understand what happened.


• Run-time crash analysis for any windows application in the environment.

• Easy access to standard mini-dump file which can be forwarded to application developers.

• Complete information gathered, no need to try and reproduce the problem.

• Historical Reporting by day and hour

Application Fault Reports

Application Faults


Application PerformanceIs my application performing optimally?

Key Questions:• How much memory is the

application consuming?• What amount of CPU time is

the application consuming?• What is the network

utilization?• What are the other running

applications consuming?• What is the change analysis?

All Processes MonitoredResource metrics to the process levelNetwork metrics to the process levelHistorical Trending

Citrix EdgeSight

Requirement:Visibility into how the applications are performing in order to make intelligent decisions for the lifecycle of that application.

Performance ReportsApplication Performance


Application StabilityHow stable are my applications?

Key Questions:• What kind of error messages

are my users seeing?• How often are the applications

going into a hang state?• How often is the application

faulting?• Is the application losing

network connectivity with its DB/App Server?

Application errorsApplication hangsApplication faultsSocket error reportsSystem, application, security event logs

Citrix EdgeSight

Requirement:To understand the stability of the applications as users run them.


• Real-Time alerts to understand frequency of stability issues

• Stability Reports to understand the day to day stability of the application across the enterprise

• Overall process issues in the environment

• Application, System, and Security Logs to understand Events on the device related to the user

Errors, Hangs, Faults, System EventsApplication Stability


Identifying Infrastructure IssuesWhere is the issue?

Key Questions:• Is the server running

optimally?• Are my core Presentation

Server applications performing normally?

• Does the network show latency or connection issues?

• Are the applications showing stability issues?

• What else is consuming resources on my users PC?

All Processes MonitoredNetwork Performance MetricsApplication StabilityEndpoint Monitoring

Citrix EdgeSight

Requirement:To focus troubleshooting time and effort in the right place


Identifying Infrastructure Issues

•Real-Time Summary to show Network, Memory, Alerts, and Processor

• Real-Time Network reports to analyze the Delay, RTT, and Volume of traffic

• Network Delay for a Device to understand the delays coming off the devices

• Network Delay by Port to see the devices across the farm

Device, Application, Network


Capacity PlanningHow taxed is my environment?

Key Questions:• Can my servers support the

users from a hardware standpoint?

• Do the applications perform efficiently?

• Is the network capable of bandwidth my apps are consuming?

• Can my users desktops handle the application?

Application Faults


“Application performance problems at remote clinics that was discovered to be caused by multicast storms on the wan segment that the networking team initially didn’t think were possible.”

Application Performance


“EMR error tracking and reporting to the application owner that is allowing us to fix many errors in the application that were never being reported by the nursing staff. Our environment with generic login thin clients, no one wants to “own” a problem by letting the help desk know, so they just leave it broken and never report it.”
