3. If it’s not there
you can’t see it

4. Logs
 IIS Logs



HTTP Errors
Redirects
Internal Server Errors
 Windows Event Logs (Cloud Service Only)
 Performance Counters


Memory, CPU, Disk Access, Requests
Custom Counters (Cloud Service Only)
 Trace Logs

Trace.XXX()

Web Site Logs

9. Setting up Cloud Service Logging
 Programmatically




During role initialization
Enable diagnostics and storage transfer settings
Enable windows logs
Enable performance counters
 WADcfg (preferred)


Used to be XML raw
Now VS has user experience

Cloud Service Logs

11. Managing Logs
 What if you have many sites and cloud services

Aggregate into single table
 You’ll need filters



By application
By type of log
By deployment
 Can create filters with management tool

I.e., Cloud Storage Studio

12. Make logging
EASY

13. Encapsulate Logging
 Simplify logging for the developer
 Create a DiagnosticsHelper



Methods for Debug, Info, Warning, Exception tracing
Methods for throwing exceptions throughout application
A method for serious exceptions, send email on exception to admin
 Be sure to swallow DiagnosticHelper exceptions

Logging should not introduce new issues, wrap that up!
 Can be shared


Web Sites
Cloud Services

15. ETW is fast
DO NOT be afraid to use it

16. Event Tracing for Windows (ETW)
 Part of the Windows operating system since Windows 2000

Tools have improved significantly since then
 Tools for developers, for IT and for customers to work with
 Highly efficient tracing mechanism with decoupled architecture
 Enable or disable dynamically

No application restarts required
 Available to Azure Cloud Services and Web Sites

you won’t know it’s there

19. Monitoring
 Performance Counters



Memory
CPU

26. Service Levels and Reports
 Customers want proof of SLA compliance
 Your average up time measured monthly



Not including scheduled downtime
Sometimes scheduled downtime is limited
99.95 availability is typical
 Your average request time measured monthly


Should exclude special services/page (i.e. data upload, large reports)
2s per request average is usually desired, an SLA may state 5s (whew)
