AGENDA
•End-to-end monitoring, what and why?
•Recent updates
•Available tooling
After the session, you’ll have an overview of Azure E2E
monitoring techniques, whether you’re an IT Professional of a
Developer.

@fincooper #TUGAIT
WHAT AND WHY
•By E2E I mean full-stack and
actionable monitoring of:
▪Availability
▪Health
▪Performance
▪Security
▪SLA
•Having E2E monitoring infrastructure
in place helps you to :
▪Know how your application performs
▪Understand how users use your app
▪Fix issues and bugs faster
▪Helps you answer “is it my app or
Azure”

APP INSIGHTS APPLICATION MAP
• Maps your application component dependencies
• Monitoring of load, performance, failures and alerts, at
component level
• You can drill down to a speific Azure Monitor or Azure Service
diagnostic view, such as SQL Database Advisor
• Helps you spot the problemmatic component more easily

@fincooper #TUGAIT
APP INSIGHTS WEB TEST ALERTS
Availability test
•You can test any website
•Up to 16 Azure locations supported
•Not just HTTP response: can be configured to require certain
content to be retrieved (welcome text, image etc)

@fincooper #TUGAIT
APP INSIGHTS WEB TEST ALERTS
Recorded step tests
Recorded steps support:
• Session recording with Visual Studio or browser
• Timing and random number input
• Authentication with SAML or AAD

@fincooper #TUGAIT
APP INSIGHTS ML ALERTS
•Failure Anomalies.
•Performance Anomalies.
•Azure Cloud Service issues.

@fincooper #TUGAIT
APP INSIGHTS POWERBI PACK
•Combine metrics from
multiple applications in
one portal for self-
service BI
•Premade visualisations
for active users, page
views, sessions, browser
and OS version, and
geographic distribution of
users in a map

@fincooper #TUGAIT
SCOM MONITORING
•Two important Azure-related Management packs for System Center
Operations Management
▪SCOM Azure Management Pack
▪SCOM Application Insights Management Pack (new)
•You can add App Insights at build-time to get performance monitoring
capabilities to SCOM.
▪If you implement App Insights SDK in your web application, you can also
expose this custom telemetry in SCOM

SCOM MONITORING

@fincooper #TUGAIT
OMS MONITORING
•Operation Management Suite (OMS) provides several infrastructure
monitoring capabilities out of the box:
▪Network Performance Monitoring
▪Storage, compute and Microsoft middleware performance
•With OMS, you can use a powerful Lucene-based query engine to
search trough your System Center / daemon logs
▪You can ask e.g. for data on all unhealthy network links
▪Or status of disk usage and patching for all VMs
•You can also bring all Application Insights telemetry into OMS search
logs!

@fincooper #TUGAIT
OMS SERVICE MAP
•Built on the BlueStripe acquisition
•Automatically maps dependencies of your Windows or Linux VMs
▪Shows connections between servers, ports and processes
▪You need to install an agent
•Use Service map to gather a holistic SLA view on your IaaS appications
▪Drill down to machine level to see OMS performance monitoring data
▪Think Application Map for infra!
