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

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

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
