Are we all developers (or related)? Who has heard of DFO? Design for Operations Who thinks stack traces in event logs are cool? Who thinks editing an XML configuration file in notepad to reconfigure your application is a good idea?

Design for Operations Windows Eventing, Performance Counters & WMI Windows PowerShell PowerShell Cmdlets MMC 3.0

Design for Operations Building applications that can be deployed Building applications that can be operated Caring about Operations [And about your debugging friends at Microsoft]

Developers build applications in a silo Hand application over to Operations Operations operate the application Applications can’t be configured or monitored with management tools used by IT Staff No Knowledge Sharing Developers required to troubleshoot No Feedback Loop

Health Model “What is not working and how bad is it?” How to Detect something is wrong How to Correct problem Realized through Instrumentation Events Performance Counters WMI

Online Offline Failed Performance Problem Dependency Problem Other Problem Security Problem Integrity Problem Started (All processes started) Stopped (All processes stopped) Shut down (All processes killed) Failed (Event: Can’t recover can’t even stop) Problem Detected (Event: Database is not available) Recovered Successfully (Event: Database reconnection established) Degraded

WMI Provider WMI Events WMI Properties.NET Application EventsConfiguration Performance Counters & Diagnostics Event Logs (Application, User Defined) Performance Counters Debug Tracing

Register Event Log Source Write Event if(!EventLog.SourceExists(“Source”)) { EventLog.CreateEventSource(“Source”,”Log”); } if(EventLog.SourceExists(“Source”)) { EventLog myEventLog = new EventLog(); myEventLog.Source=“Source”; myEventLog.Log=“Application”; myEventLog.WriteEntry(“Event Message”, EventLogEntryType.Information, 1000, 45); myEventLog.dispose(); }

Create Event Class Derive from BaseEvent Fire the event public class CustomWmiEvent : BaseEvent { private string eventName; public string EventName { set { eventName = value; } } CustomWmiEvent wmiEvent = new CustomWmiEvent(); wmiEvent.Fire();

Why Use Windows Eventing 6.0? Better Performance Declarative Event Structure (Meta Data/Discovery) XML based Subscriptions Unified API for Eventing and Tracing Integration with Task Scheduler Any problems? No managed API… Yet… Really sorry… I mean it…

Install Counters if (PerformanceCounterCategory.Exists("MySampleCategory")) { PerformanceCounterCategory.Delete("MySampleCategory");} System.Diagnostics.CounterCreationDataCollection CounterDatas = new System.Diagnostics.CounterCreationDataCollection(); // Create the counters and set their properties. System.Diagnostics.CounterCreationData cdCounter1 = new System.Diagnostics.CounterCreationData(); cdCounter1.CounterName = "SimpleCount"; cdCounter1.CounterHelp = "Just a simple numerical count"; cdCounter1.CounterType = System.Diagnostics.PerformanceCounterType.NumberOfItems64; // Add both counters to the collection. CounterDatas.Add(cdCounter1); // Create the category and pass the collection to it. System.Diagnostics.PerformanceCounterCategory.Create("MySampleCategory", "My Sample Category Counters", CounterDatas);

Increment Data private PerformanceCounter _Counter1; … try { _Counter1 = new PerformanceCounter("MySampleCategory", "SimpleCount", false); } … if (_Counter1 != null) { _Counter1.Increment(); }

What is Windows PowerShell? Command Line Shell and Scripting Language Why use Windows PowerShell? A shell that knows.net! Makes ITPro’s and Developers talk the same language! Automates Bulk System Administration Tasks Help gain greater control of system Easy to build Custom Windows PowerShell Commands Easy to Provide GUI (via MMC or Windows Forms)

Steps to Building CmdLets 1. Download Windows PowerShell 2. Download the Visual Studio Template for Windows PowerShell Create a New Windows PowerShell Project 4. Complete the SnapIn Class Definition 5. Add Classes for your CmdLets 1. Add Attributes 2. Derive from PSCmdLet 3. Implement ProcessRecord 6. Build and Register 1. Use InstallUtil to “install” the snapin 7. Load Into PowerShell 1. Add-PsSnapIn

What is Microsoft Management Console 3.0? Provides a common administration GUI Why use Microsoft Management Console 3.0? Build administrative consoles Same technology Windows uses Consistent management experience for administrators Admin dudes love it!
