New monitoring for existing vendor classes

I’ve seen this question come up a few times in the forums, and thought I would write a quick post on correct targeting for monitoring instances of an existing class.

For example, let’s say you have the Exchange 2013 management pack installed and you want to collect some additional counters on Exchange Server 2013. You can easily create these counters, either by using the Operations Console or Visual Studio Authoring Extensions (or you favorite xml editor), and target the rule/monitor correctly.

You will need to add a reference to the Exchange pack either way. If you are using VSAE, it’s very easy to do this. If you are using some other xml editor, then you need to add the reference to the manifest section of you custom pack. VSAE is always going to be the easiest way to add references and target a sealed vendor public class.

If you are using an xml editor, an easy way to figure out what class to target is to open the pack with MPViewer and then taking a look at the Exchange Server class.

If you click on the Raw XML tab in the details pane, you will see the class id you need to put into the target of your new rule or monitor.

Another easy way to find the class id of your target is to use the Operations Command Shell. For example:

get-scomclass -displayname ‘Exchange Server’ | select name, id

These are just some options for finding the correct class id. If you are creating these monitors/rules using the Operations Console, then you don’t need to worry about finding the class id – the Operations Console will automatically add the correct id and give it a UI namespace.

Please target responsibly.

What is required for Visual Studio Authoring Extensions?

This post had been updated on November, 2014 with important licensing considerations.

 

If you are interested in diving into the authoring extensions, but don’t want to commit by spending money on the full Professional or Ultimate editions of Visual Studio, you have a couple options.

Previously, you could have first installed the Isolated Shell, then the Integrated Shell. Once that is done, go ahead and install the VSAE.

Recently, Microsoft had released Visual Studio Community 2013, which allows us to use the authoring extensions as well.

IMPORTANT NOTE!!!

There are specific licensing terms that need to be read in the fine print. In some cases, you may not use the free “community” edition or the “shell” versions to develop management packs for your organization.

You must read the Visual Studio Licensing Whitepaper to understand when and how you may use these free versions.

Monitor Percent Memory Used

I’ve seen this in the forums quite a bit, so I felt I should write a pack that monitor for Windows % memory used. I basically just took the script from the Windows packs, that claims (in the script comments) to work across all base Windows OS’s, and plugged it into a data source. Then I created a monitor type and a unit monitor.

I will post the xml here, but you can also download the management pack at the end of the post. I have only tested this on Windows 2008 and Windows 2012. As the base OS script says, it’s compatible with all versions. The default target of the unit monitor is Windows Server Operating System, so keep that in mind. The unit monitor is enabled by default. Because it target Windows Server Operating System, the Source of the alert will be just that; it will not be the computer name.

By default, it runs every 15 minutes and has a threshold of 90%. It will alert after 2 intervals over threshold. You can override interval, threshold, and match count. MatchCount is the number of intervals over threshold before generating an alert. You choose how you want to implement it 🙂

If you have a request for a new rule or unit monitor, ask in the comments section and I’ll do what I can to expand on this pack.

Find base class, hosting class, and all properties using powershell

A few years ago, I wrote a powershell script that returns the entire base and host class path for a given class, including all available properties on each of the classes. This can be useful in a few different scenarios, including management pack development.

I haven’t used the script in a while, but the other day ran into a situation where it was quite handy. I had to update it to work with SCOM 2012, however, so I thought I would post the updated script here for future reference.

You can find the SCOM 2007 version here.

 

##This script accepts a class name, and returns the entire
##Base class path.  It also returns Host Class for each
##Base class returned.  You'll see the entire
##class path for the given class.

Automate management packs using powershell

I’ve been asked on a few occasions to automate management packs. Unfortunately, there isn’t much information about how to do to do this using Powershell in the MSDN development kit. I am providing a couple Powershell functions you can add to your automation process that will generate a new management pack.

Just update the output directory, pack name, pack display name, and version in the highlighted lines.

 

function CreateNewPack ($id, $name, $version) {
    $mpStore = New-Object Microsoft.EnterpriseManagement.Configuration.IO.ManagementPackFileStore
    $managementPack = New-Object Microsoft.EnterpriseManagement.Configuration.ManagementPack($id, $name, (New-Object Version(1,0,0,$version)), $mpStore)
    $managementPack.DefaultLanguageCode = 'ENU'
    $managementPack.DisplayName = $name
    $managementPack.Description = $name + ' management pack was auto-generated'
    $managementPack
}
function WriteManagementPack ($directory, $mp) {
    $mpWriter = new-object Microsoft.EnterpriseManagement.Configuration.IO.ManagementPackXmlWriter($directory)
    $mpWriter.WriteManagementPack($mp) | Out-Null
}
$directory = 'c:\My Pack'
$mp = CreateNewPack 'MyNewPack' 'My New Pack' 1
$mp.AcceptChanges()
WriteManagementPack $directory $mp
