Application Monitoring Challenges

Development

IT Operations

“Why? It works fine in

staging”

“But I only know it’s unavailable when my

customers call”

“So how is it failing?”

“How should I know, I didn’t write the code”“How do I monitor your .NET application for

availability in production?”“!@$#% $^%& *^!!!”

“It is your server, not my code !”

Solution: Application Monitoring

Application Real-Time Architecture Discovery and Modeling

•Discover and gain insight into the relationships between the software and hardware components within your application environment

End User Experience Monitoring

•Understand how your end users experience your application’s performance and quality

User-Defined Transaction Profiling

•Trace the performance of specific critical business transactions across the application stack and infrastructure

Application Component Deep Dive Monitoring

•Monitor the health of an application, and rapidly diagnose problems

Application Performance Analytics

• Optimize Resources

• Improve Business Processes

Diagnostic Information

Problem Resolution

Identifying Problems

Operations Manager State view indicates

application health Alerts indicate application

problems Notifications and actions can

be configured based on alerts

AVIcode View events by time Create notifications for

alerting directly from web console

Using SCOM for Alerting

Alert Types AVIcode events

with diagnostic detail

Alerts based on app performance counter deviations

Monitors Based on

application performance counters

Search for:

Isolating the Problem?

AVIcode Events are correlated and categorized across monitored

application tiers to isolate the problem area

Host metrics are correlated application events to expose relationships between app and resources

Operations Manager Synthetic monitoring to understand application availability

Monitor host platform/services health to understand when dependent services are experiencing problems

How Do we Diagnose an App Problem?

Leverage AVIcode to diagnostic information to understand what the app/user was executing

Determine if its an operational or application support issue

Initiate incident / problem management processes to route information to appropriate teams

Analyzing Real-time Application Events

Event Types

Events are divided into 4 major categories Application Errors

Performance

Operational Info

System Failures

Application failures are further dividedinto one of three Aspects Application Failure

Connectivity

Security

Performance Events

Client-side Performance Event Breakdown

Server-side Performance Event Breakdown

Application Failure Events

Client-side JavaScript exception

and parameters Ajax request failures

Server-side Server-side application

exceptions Categorized by app failure,

security and connectivity

Client-side JavaScript Failure Breakdown

Server-side Failure Event Breakdown
