PowerShell Monitor Fragment with Run As

Stop!

 

Ever need to run a PowerShell command (or script) as a specific ID?

Maybe you need to know when the command fails to catch degraded application health?

 

Let’s work into the scenario with a MP Fragment

Load Test MP fragment

Shout to Tyson Paul for his initial MP with 2016, catch his blog here!

 

This should help speed up building the MP if you have Visual Studio 2013 or 2015 with Visual Studio Authoring Extensions (VSAE).  Read Kevin Holman’s blog if this is new

Quicker method To build the MP as MP fragment, update the following:

  1. Import MP Fragment into Visual Studio for MP
  2. Replace variables in fragment
    1.   ##CompanyID##
    2.   ##AppName## – LoadTesting
    3.   ##ClassID## – WindowsServer
    4.   ##OSVersion## – 2012 = 6.2, 2012R2 = 2012.R2, 2016 = 100
    5.   ##MPReferenceID## – MWS2M for 2012, MWS2RM for 2012R2
    6.   ##RuleGUID##
  3. Obtain Rule names for Override Targets and Report rule GUID’s for the report parameters section

          get-scomrule | ? { $_.DisplayName -like “System Processor Queue Length*” } | fl ID,DisplayName,Name

          get-scomrule | ? { $_.DisplayName -like “Current Disk Queue Length*” } | fl ID,DisplayName,Name

          get-scomrule | ? { $_.DisplayName -like “Current Disk Queue*” } | fl ID,DisplayName,Name

          get-scomrule | ? { $_.DisplayName -like “Current Dis*k Queue*” } | fl ID,DisplayName,Name

          get-scomrule | ? { $_.DisplayName -like “*Current Disk Queue*” } | fl ID,DisplayName,Name

          get-scomrule | ? { $_.DisplayName -like “*Average Disk Seconds Per Transfer*” } | fl ID,DisplayName,Name

          get-scomrule | ? { $_.DisplayName -like “*Logical Disk Idle Time*” } | fl ID,DisplayName,Name

          get-scomrule | ? { $_.DisplayName -like “*Processor Time Total*” } | fl ID,DisplayName,Name

          get-scomrule | ? { $_.DisplayName -like “*Memory Available Megabytes*” } | fl ID,DisplayName,Name

          get-scomrule | ? { $_.DisplayName -like “*Network Adapter Bytes Total*” } | fl ID,DisplayName,Name

          get-scomrule | ? { $_.DisplayName -like “*Memory Pages per Second*” } | fl ID,DisplayName,Name

          get-scomrule | ? { $_.DisplayName -like “*System Processor Queue Length*” } | fl ID,DisplayName,Name

  1. Save and Import MP into environment
  2. Get Report parameter value for group ID

          get-ScomGroup | ? { $_.DisplayName -like “*Load Testing Group*” } | fl ID,DisplayName

  1. Update ##TargetGroupID##, MP version
    1. Save MP, and import into environment
  2. From SCOM Console, Authoring Tab
    1. Update group with explicit members
    2. Verify Group members
  3. From SCOM Console, Monitoring Tab
    1. Verify Performance view has performance counters
  4. From SCOM Console Reporting Tab (this may take a few minutes to push report to Reporting server)
    1. Open report and run
    2. Export data for analysis

Load Test MP with Report

Read below if you want a specific MP for load testing

 

I don’t know about you, but I’ve come across the situation where you need to compare performance.

 

This MP should help validate performance, whether to validate physical versus virtual, or a new Server Farm, storage performance between environments, etc.

Let’s start with the MP shell

 

Check out the upcoming Gallery download for MP’s and fragments here

NOTE: GUID’s will vary to your environment

 

To build the MP, you will need to update the following:

 

Pack ID to include the OS version

 

Add Reference for OS Monitoring MP (can use Visual Studio (VS) MP alias if VS is available for use in your environment)

Class Type ID with OS version

Discovery ID and Target with OS Version

 

Overrides ID with OS Version, and Target with OS MP Rule name and reference

Use the OS Monitoring MP to help with the rule names

The far right of the Override lists the Rule that must match to the OS MP

 

View ID with OS Version

 

Folder Item Element ID and ID

 

MP Display Strings with OS Version

 

Save and Import MP without the Report parameter to see what Group ID SCOM assigns the Load Test group

 

 

Part 2 – include report after group is imported

Don’t forget to update MP version under Identity!

Get Report parameter value for group ID

From PowerShell

          get-ScomGroup | ? { $_.DisplayName -like “*Load Testing Group*” } | fl ID,DisplayName

Alternatively, obtain from SQL SSMS

          select [ManagedEntityDefaultName],[ManagedEntityRowId]

          FROM [vManagedEntity]

          where [ManagedEntityDefaultName] like ‘%load%’

          order by displayname

SSMS Output

 

In MP XML, update View Target GUID to your Group ID

 

Add Report section, and update parameter values Rule GUID

 

PowerShell commands to run from MS or console installed machine

The GUID’s needed for the report parameters section

 

get-scomrule | ? { $_.DisplayName -like “System Processor Queue Length*” } | fl ID,DisplayName,Name

get-scomrule | ? { $_.DisplayName -like “Current Disk Queue Length*” } | fl ID,DisplayName,Name

get-scomrule | ? { $_.DisplayName -like “Current Disk Queue*” } | fl ID,DisplayName,Name

get-scomrule | ? { $_.DisplayName -like “Current Dis*k Queue*” } | fl ID,DisplayName,Name

get-scomrule | ? { $_.DisplayName -like “*Current Disk Queue*” } | fl ID,DisplayName,Name

get-scomrule | ? { $_.DisplayName -like “*Average Disk Seconds Per Transfer*” } | fl ID,DisplayName,Name

get-scomrule | ? { $_.DisplayName -like “*Logical Disk Idle Time*” } | fl ID,DisplayName,Name

get-scomrule | ? { $_.DisplayName -like “*Processor Time Total*” } | fl ID,DisplayName,Name

get-scomrule | ? { $_.DisplayName -like “*Memory Available Megabytes*” } | fl ID,DisplayName,Name

get-scomrule | ? { $_.DisplayName -like “*Network Adapter Bytes Total*” } | fl ID,DisplayName,Name

get-scomrule | ? { $_.DisplayName -like “*Memory Pages per Second*” } | fl ID,DisplayName,Name

get-scomrule | ? { $_.DisplayName -like “*System Processor Queue Length*” } | fl ID,DisplayName,Name

 

 

Verification

  1. From SCOM Console, Authoring Tab
    1. Update group with explicit members
    2. Verify Group members
  2. From SCOM Console, Monitoring Tab
    1. Verify Performance view has performance counters
  3. From SCOM Console Reporting Tab (this may take a few minutes to push report to Reporting server)
    1. Open report and run
    2. Export data for analysis
