Step-by-Step – Installing System Center Operations Manager (SCOM) 2019 on Windows Server 2019 with SQL 2017

This post I will be installing System Center Operations Manager 2019 (SCOM) RTM, Build Number 10.19.10050.

Here is some of the background information. As this post will concentrate on the installation of SCOM 2019, I am going to omit the setup and configuration of the Domain Controller, Windows Server 2019 for the SCOM Management Server. Also to note, I am using a PaaS instance of SQL 2017 (hosted on Azure), likewise the entire environment lives on Azure in an IaaS and PaaS configuration.

Service Accounts and Local Administrator:

DomainAccount Description Local Admin on…
domainSCOM_AA SCOM Action Account SCOM
domainSCOM_DA SCOM Data Access/SDK Account SCOM
domainSCOM_SQL_READ SCOM SQL Reader n/a
domainSCOM_SQL_WRITE SCOM SQL Writer n/a
domainSCOM_Admins SCOM Administrators Group SCOM
domainSQL_SA SQL Service Account n/a

Now, if you’re lazy like me, or are tired of doing this setup for environments, I have scripted the automation of these accounts. You can find that link here, Microsoft TechNet Gallery.


Let’s Begin:

Since I am hosting SQL on a dedicated server, I will install SSRS (SCOM Reporting) on that server.

Well, that’s not new… Prerequisites. Since this is a clean, vanilla Windows 2019 server, we will need to install all the necessary Web Console components, along with Report Viewer Controls (probably SQL CLR Types too..).

  • For the Report Viewer Prerequisites, go HERE.
  • Here is the PowerShell command I ran to install the necessary IIS features/roles:
Import-Module ServerManager
Add-WindowsFeature Web-Server, Web-WebServer, Web-Common-Http, Web-Default-Doc, Web-Dir-Browsing, Web-Http-Errors, Web-Static-Content, Web-Health, Web-Http-Logging, Web-Log-Libraries, Web-Request-Monitor, Web-Performance, Web-Stat-Compression, Web-Security, Web-Filtering, Web-Windows-Auth, Web-App-Dev, Web-Net-Ext45, Web-Asp-Net45, Web-ISAPI-Ext, Web-ISAPI-Filter, Web-Mgmt-Tools, Web-Mgmt-Console, Web-Mgmt-Compat, Web-Metabase, NET-Framework-45-Features, NET-Framework-45-Core, NET-Framework-45-ASPNET, NET-WCF-Services45, NET-WCF-HTTP-Activation45, NET-WCF-TCP-PortSharing45, WAS, WAS-Process-Model, WAS-Config-APIs -restart

 

Once the server is back online, you will need to register ASP.Net.

6

You will need to apply the following using Command Prompt (as Administrator)). Yes, this is a screenshot from a previous post…Forgot to capture the screenshot when running it this time..

  1. cd %WINDIR%Microsoft.NETFramework64v4.0.30319
  2. aspnet_regiis.exe -r
  3. IISRESET
  4. Reboot your server…

Once the server is back online, let’s try that Prerequisites check again….

Great! Now all of Prerequisites have been met!

Provide a meaningful Management Group Name (there’s no going back after this…)

SQL Server will be where your SCOM SQL instance(s) were installed. Remember, to either disable the Windows Firewall, or open SQL TCP Ports 1433.

 

I recommend always keeping this off, and manually updating your SCOM infrastructure.

One quick review. Looks good. Hit Install, and get some fresh air!

A few minutes later….

Sweet! All good. I hope this helps. If you have any questions or issues, please drop me a line.

Happy 2019 SCOM’ing!

What’s new in System Center Operations Manager (SCOM) 2019?

When it comes to monitoring your on-premises datacenter, System Center Operations Manager (SCOM) is still the tool of choice. The System Center stack has been the Microsoft go-to toolset for decades for datacenter management. System Center 2019 it is expected be made Generally Available (GA) in the next few weeks, as Q1 comes to an end.

It is also worth mentioning, SCOM and the entire System Center 2019 stack will be following the Long-Term Servicing Channel (LTSC) model.

Some of the key features that will be highlighted with the release of SCOM 2019 are below.

  • Improved Azure Management Pack (faster and easier to manage)
  • Improved HTML5 dashboards – The new web console has no dependencies on SilverLight and is officially HTML5
  • Azure Service Map Integration
  • Enhanced notifications and alert management – Rich HTML notifications are now default
  • Customize and Preview HTML notification content
  • Email notification improvements such as the ability operators (‘OR’ and ‘EXCLUDE’) to the criteria builder
  • Backend support for SQL Server 2017 and SilverLight dependencies removed
  • Enhanced Agentless alerting during failover scenarios
  • Enhanced certificate validation for Web Application monitoring
  • Application Performance Monitoring (APM) support for CSM (Client Side Monitoring) for Edge and Chrome
  • Support for OpenSSL 1.1.0 for Linux platforms
  • Kerberos support for Linux agent
  • Linux log file monitoring (any custom datasource ie. docker/kubernetes container monitoring)

Happy Retirement SCOM GSM (Global Service Monitor)

Earlier this month, Microsoft announced that the SCOM’s (Operations Manager) GSM (Global Service Monitor) will officially call it quits and retire the service, effectively, November 7th, 2018. As it is a sad day for us, long-time SCOM administrators, the future remains bright, as Microsoft makes way for Application Insights. Over the last year or so, I have done numerous presentations and conferences on Azure’s Application Insights (App Insights), and demonstrating the natural evolution from SCOM APM to Azure App Insights. However, before we start talking about Azure’s App Insights, we need to start thinking about migrate away from GSM.

If you don’t know, GSM, Global Service Monitor in System Center Operations Manager provides the ability to monitor the availability of external web-based applications from multiple locations throughout the world. Microsoft Azure has this feature already within App Insights, called, “Availability“. Creative, I know.. But it does exactly that, measures the availability of your application.

Fellow MVP, Kevin Greene wrote an amazing, and in-depth article on how to migrate your application and GSM to Azure App Insights, so please have a read here. Over the next few blog posts, I would like to provide some detailed demos on Application Insights and how you can start taking advantage of this service to start monitoring your applications.

Enabling SCOM 2016 Agent Proxy

Not too much has changed when it comes to SCOM 2012R2 and SCOM 2016. This post is a similar post to SCOM 2012R2, but applicable to SCOM 2016. (See that post here).

You could go to the computer that SCOM is complaining about and manually enable the agent proxy via Administration > Managed Computers, and modifying its properties, see below:

Or…… you could make your life easier, and do this…

The fix is easy, and the explanation are both below:

To resolve the “Agent proxy not enabled” alert for all machines in your current environment, run the following PowerShell code in the SCOM PowerShell Console:

get-SCOMagent | where {$_.ProxyingEnabled -match "False"} | Enable-SCOMAgentProxy

To prevent this alert in the future, run the following below:

add-pssnapin "Microsoft.EnterpriseManagement.OperationsManager.Client"; new-managementGroupConnection -ConnectionString:<strong>yourSCOMMGMTserverFQDNhere</strong>; set-location "OperationsManagerMonitoring::"; Set-DefaultSetting -Name HealthService\ProxyingEnabled -Value True
