SCOM Performance Data and Power View

SCOM Performance Data and Power View

In a previous post (http://www.scom2k7.com/performance-reporting-with-power-view/) I presented a simple example of performance reporting using Power View in Excel 2013. The purpose of this post is to update the performance model for scalability and customization. Power View has limits on the volume of data and the presentation area which influence the design of the Power Pivot data model. My primary goal is to maximize the speed at which I can view data in a clear, meaningful way. I will provide an outline of the data model, the SQL queries to populate it, and the DAX statements to manipulate the data. The procedure for adding the data source and datasets has not changed from the previous post, and I will skip the specific steps here.

I use a data model similar to the performance dataset in the Operations Manager Data Warehouse schema (http://technet.microsoft.com/en-us/library/gg508713.aspx). However, I go from the instances (vPerformanceRuleInstance) to the objects and counters (vPerformanceRule) before going to the data collection rules (vRule). The object\counter pairing forms a unique string for combining with technical knowledge. I should point out that my use of the term "technical knowledge" refers to an arbitrary set of attributes for describing performance counters. For example, I might describe "LogicalDisk\Avg. Disk sec/Transfer" like this:

Object+Counter

Technology

Category

Purpose

LogicalDisk\Avg. Disk sec/Transfer

OS

Storage

Latency

This helps keep values visible in tiles and legends while communicating the meaning to an audience. The attributes become useful in filtering, too. For this post I will use an Excel workbook for storing technical knowledge, but these could be columns in a SQL table, SQL query or calculated columns in the data model.

 

Overview

A. Create Performance Data Model

B. Add Measures and Calculated Columns

C. Add Attributes for Object\Counter Values

D. Create Relationships

E. Make a View for All Servers

F. Make a View for Individual Servers

 

Step by step

A. Create Performance Data Model
  1. Set up Excel 2013
  2. Create a data source for the SCOM Data Warehouse with the following query:

    /*Perf*/

    SELECT     PERF.ManagedEntityRowId

    ,PERF.PerformanceRuleInstanceRowId

    ,PERF.DateTime

    ,PERF.AverageValue

    ,PERF.MinValue

    ,PERF.MaxValue

    ,PERF.SampleCount

    FROM Perf.vPerfHourly PERF

    INNER JOIN vPerformanceRuleInstance PRI ON PRI.PerformanceRuleInstanceRowId = PERF.PerformanceRuleInstanceRowId

    INNER JOIN vPerformanceRule PR ON PR.RuleRowId = PRI.RuleRowId

    WHERE PERF.DateTime > (GETUTCDATE() - 7)

    ORDER BY PERF.DateTime 

     

  3. Add additional datasets for each of the following queries:

    /*Object and Counter*/

    select *

    from vPerformanceRule PR

     

    /*Instance*/

    select *

    from vPerformanceRuleInstance PRI

     

    /*Rule*/

    select RU.RuleRowId

    ,RU.ManagementPackRowId

    ,RU.RuleDefaultName

    from vRule RU

    inner join vPerformanceRule PR on PR.RuleRowId = RU.RuleRowId

     

    /*MP*/

    SELECT distinct MP.ManagementPackRowId

     ,MP.ManagementPackDefaultName

     ,MP.ManagementPackSystemName

    FROM vManagementPack MP

    inner join vRule RU on RU.ManagementPackRowId = MP.ManagementPackRowId

    inner join vPerformanceRule PR on PR.RuleRowId = RU.RuleRowId

     

    /*Entity*/

    select distinct

    ME.ManagedEntityRowId

    ,MET.ManagedEntityTypeDefaultName as METype

    ,TLMET.ManagedEntityTypeDefaultName as TLMEType

    ,ME.TopLevelHostManagedEntityRowId

    ,ME.ManagementGroupRowId

    ,ME.Name

    ,ME.DisplayName

    ,ME.Path

    ,ME.ManagedEntityTypeRowId

    from Perf.vPerfDaily PERF

    inner join vManagedEntity ME on ME.ManagedEntityRowId = PERF.ManagedEntityRowId

    inner join vManagedEntityType MET on MET.ManagedEntityTypeRowId = ME.ManagedEntityTypeRowId

    inner join vManagedEntity TLME on TLME.ManagedEntityRowId = ME.TopLevelHostManagedEntityRowId

    inner join vManagedEntityType TLMET on TLMET.ManagedEntityTypeRowId = TLME.ManagedEntityTypeRowId

    where PERF.DateTime > (GETUTCDATE() - 7)

    order by ME.ManagedEntityTypeRowId

     

Note: The vPerformanceRule and vPerformanceRuleInstance views could be added as tables, but I prefer to use queries in case I want to add conditions later. For example, if I want to exclude LogicalDisk counters or dynamic instances.  

 

B. Add Measures and Calculated Columns

  1. Add a Column to the Perf dataset and rename it

    DAX

    Column Name

    =DATEVALUE([DateTime])

    Date

  2. Click an empty field in the section below the data columns 

  3. Enter max_max:=MAX([MaxValue]) in the function field (right below the ribbon) to create a measure 

      

  4. Add additional measures for other statistics                

    Measure Name and DAX

    avg_max:=AVERAGE([MaxValue])

    avg_avg:=AVERAGE([AverageValue])

    avg_min:=AVERAGE([MinValue])

    min_min:=MIN([MinValue])

  5. Add a column to the Object and Counter dataset and rename it

    DAX

    Column Name

    =CONCATENATE(CONCATENATE([ObjectName],"\"),[CounterName])

    Object+Counter


  6. Add columns to the Entity dataset and rename them

    DAX

    Column Name

    =IF([TopLevelHostManagedEntityRowId]=[ManagedEntityRowId],1,0)

    TLME

    =IF([TLME]=1,[DisplayName], [Path])

    FQDN_Rough

    =MID([FQDN_Rough],1,FIND(";",[FQDN_Rough],1,255)-1)

    FQDN

    =MID([FQDN],1,FIND(".",[FQDN],1,255)-1)

    Hostname

    =MID([FQDN],FIND(".",[FQDN],1,255)+1,255)

    Domain

    =MID([Domain],1,FIND(".",[Domain],1,255)-1)

    Domain_Short

      
  7. Add a measure to the Entity dataset

    Measure Name and DAX

    Host_Count:=DistinctCount([FQDN])

C. Add Attributes for Object\Counter Values
  1. Open a new Excel workbook
  2. Copy the Object+Counter column from the Object and Counter dataset
  3. Paste the Object+Counter column into the new workbook
  4. Create columns for Technology, Category, and Purpose
  5. Enter desired values in the columns for any or all counters (empty cells will show as "Blank" in Power View). For example:

    Object+Counter

    Technology

    Category

    Purpose

    LogicalDisk\Avg. Disk sec/Transfer

    OS

    Storage

    Latency

    LogicalDisk\Current Disk Queue Length

    OS

    Storage

    Activity

    ManagementGroupAlerts\AlertsCount

    SCOM

    MG

    Activity

    Memory\Available MBytes

    OS

    Memory

    Capacity

  • Thanks

  • I added some steps to describe adding measures. I changed "metric" to "measure," too.

  • Great post many thanks
