BRIEF SUMMARY OF EACH TOOL

Performance Monitor

–        Use to get information about the application’s health.

–        Use to see if and when the suspicious symptom happens.

–        Save a log file. It can be analyzed later.

–        Part of the Windows Operating System.

 

 

PAL (Performance Analysis of Logs)

–        The PAL tool reads in a Performance Monitor counter log (any known format) and analyzes it using complex, but known thresholds (provided).

–        The tool generates an HTML based report which graphically charts important performance counters and throws alerts when thresholds are exceeded.

–        The thresholds are originally based on thresholds defined by the Microsoft product teams and members of Microsoft support, but continue to be expanded by this ongoing project.

Process Monitor

–        Capture of thread stacks for each operation make it possible in many cases to identify the root cause of an operation

–        Reliable capture of process details, including image path, command line, user and session ID

–        Filters can be set for any data field, including fields not configured as columns

–        Advanced logging architecture scales to tens of millions of captured events and gigabytes of log data

–        Process tree tool shows relationship of all processes referenced in a trace

–        Boot time logging of all operations

Process Explorer

–        Easy way to see information from processes.

–        What is each thread doing? Call stack is available.

–        How is the CPU usage? You can see the CPU usage, Kernel and User Mode.

–        You can see which program has a particular file or directory opened.

–        You can search for a specific handle or DLL among the processes running.

MPSReport

–        Check DLL’s versions, hotfixes, software updates.

–        Compare if two machines have the same drivers, registry settings and softwares.

Download:

http://support.microsoft.com/kb/823393/

SPSReport

–        Think of MPSReport for SharePoint.

–        The SPS Reporting Tool is utilized to gather detailed information regarding a systems current configuration.

Download:

http://www.codeplex.com/spsreport

SPDisposeCheck

–        The SPDisposeCheck utility will assist you dig through your custom SharePoint MSIL assemblies looking for areas in your code that may require “closer examination” and might lead to Dispose() related memory leaks.

–        A manual code review is still required to cast out ‘false positives’ that the tool may produce in the output report

Dependency Walker

–        Scans any 32-bit or 64-bit Windows module (exe, dll, ocx, sys, etc.) and builds a hierarchical tree diagram of all dependent modules

–        For each module found, it lists all the functions that are exported by that module.

–        Detailed information about each file including a full path to the file, base address, version numbers, machine type, debug information, and more.

–        Useful for troubleshooting system errors related to loading and executing modules.

SQL Nexus

–        You don’t need to be a DBA to use this tool. J

–        You can quickly and easily load SQL Trace files; T-SQL script output, including SQL DMV queries; and Performance Monitor logs into a SQL Server database for analysis.

–        Excellent tool for isolating problems on the SQL Server side.

CLRProfiler

–        Focused on managed heap

– Who allocates what

– What objects survive

– What is on the heap

– Who is holding on to objects

–        Instrumented application writes log

–        Separate tool to analyze log offline

–        Intrusive tool

–        By default, every allocation, every call is logged

–        Expect 10 – 100 x slowdown

–        Logging can be turned off selectively for speedup

–        Not a tool to measure where time is spent

– Great tool to analyze IIS logs

– Generate great charts

– User interface easy to interact

– Downside: slower than running regular LogParser scripts

Download:

PowerShell

–        Why do you need to learn another scripting language?

–        Less code than JScript and VBScript to accomplish the same task.

–        Total integration with .NET Framework.

–        Great for administrators and developers.

–        In PFE we use PowerShell as the preferred programming language used to create tools!

–     Alternative to LogParser tool.

Download:

PowerShell is part of Windows 7 and newer versions.

For other Windows versions you can download from:

Application Verifier (for Native coded applications)

– When the application is using APIs correctly:

–        Unsafe TerminateThread APIs.

–        Correct use of Thread Local Storage (TLS) APIs.

–        Correct use of virtual space manipulations (for example, VirtualAlloc, MapViewOfFile).

– Whether the application is hiding access violations using structured exception handling.

– Whether the application is attempting to use invalid handles.

– Whether there are memory corruptions or issues in the heap.

– Whether the application runs out of memory under low resources.

– Whether the correct usage of critical sections is occurring.

– Whether an application running in an administrative environment will run well in an environment with less privilege.

– Whether there are potential problems when the application is running as a limited user.

– Whether there are uninitialized variables in future function calls in a thread’s context.

DebugDiag

–        You can create rules in order to collect dumps under specific conditions.

–        Crash rule – used for exceptions.

–        Performance rule – used for performance problems in any application, based on any Performance Monitor counter (like Procdump but with more options and UI). Also used for hangs or performance problems in IIS, based on internal ETW events.

–        Memory and Handle Leak rule – for memory leaks coming from native code.

–        Manual Dump collection– used in cases when the rules don’t apply, like performance.

–        Automated Analysis feature – DebugDiag can debug the dump for you and present a report with the findings! The dump files don’t need to be collected with DebugDiag.
