Let’s discuss SCOM SSRS permissions. The SCOM Reporting role install really comes down to three (3) things – permissions, latest SSRS EXE downloaded (for install 2019, 2022), and ReportExtensions configuration. I’ve hit some permission issues that need more ‘how to’ details.
Set SCOM Admins group permissions
Whether the permissions are set up as part of a group policy (GPO) or not, if these steps are missing, expect problems.
Verify that your SCOM Admins domain group is a local administrator on the SCOM servers (SSRS server in this case)
Right click on Start > Computer Management
Expand System Tools
Expand Local Users and Groups
Click on Groups
Double click on Administrators
Verify SCOM Admins group, or specific service/MSA accounts are listed
Computer Management with Administrators group properties documenting relevant members which include the SCOM Admins group, and any other SQL related service accounts.
Click OK
Set SQL Instance permissions for SCOM Admins group
For a smooth install, everything comes down to SCOM SSRS prerequisites. The SCOM Reporting role install really comes down to three (3) things – permissions, latest SSRS EXE downloaded (for install 2019, 2022), and ReportExtensions configuration. The go-to reference is Holman’s QuickStart deployment guides for SCOM2019 forward list the how-to starting point. This post focuses on ReportExtensions configuration, where more ‘how to’ details are needed.
Latest revision first includes a EventID 2502 monitor for scavenging failed. Second, the monitor has count logic (setup to alert with 2 events in 30 minutes). Third, EventID 2501 rule details scavenging totals. Lastly, built a weekly report to summarize the scavenging alerts (cliff notes!).

When we talk about best practices for monitoring, this will typically include (SLA) Service Level Availability. SLA is an important piece in your environment, as uptime and happy customers come with a high SLA. There are some cases where IT Teams do work on demand. On-demand work is outside of a standard change window, a scheduled change. Typically this is outside configuration management tools, responsible to update software (applications/packages), machines, drivers, compliance settings, and more. In the one-off, non-scheduled maintenance or recovery, try leveraging ‘SCOM Agent Maintenance’ PowerShell commands on SCOM agents.
SCOM Agent maintenance PowerShell commands
cd “C:\Program Files\Microsoft Monitoring Agent\Agent”
It’s that time again, time to update SQL. Just in case your configuration management solution automatically add SQL updates, you can be prepared. Secondly, if you have to tell the configuration management team to approve updates, patches, this will help jumpstart that process. Either way, knowing about the updates helps you make decisions for your organization’s change process. I believe ‘knowledge is power’, so power up and take away whatever you need to keep up to date.
Subset of the SQL product group released ‘new SQL updates’ in July

Depending on requirements, creating multiple subscriptions within SCOM to leverage subscriber/channels required. Selecting rules/monitors, and resolution state conditions to help Application teams get incidents for key issues requiring intervention. NOTE Depending on what was command channels were created for various AssignmentGroup(s) and Team(s) within the organization.

Specific Subscription details: +CRITERIA = ALL Alerts +SUBSCRIBER = CHANNEL New-SNowEvent.ps1 via POWERSHELL +CHANNEL ServiceNow SNOW Event Creation Channel
New-SNOWEvent.ps1 command channel creates ServiceNow SNOW events for alerts and incidents.
This channel will also update the SCOM alert TicketID, Owner, ResolutionState to modify SCOM alert with SNOW information, or information passed in SNOW event.

Read the ‘Configure SCOM Subscribers’ blog to build out the SNOW subscribers for multiple PowerShell command channels. Create subscribers according to design requirements.
CHANNEL New-SNowEvent.ps1 via POWERSHELL
Follow the screenshots and fill in the wizard per the steps below.
Time to update SCOM, specifically to ‘create SCOM Command Channels’, then subscribers, and subscriptions. Depending on requirements, create multiple channels within SCOM.
Save .ps1 file(s) to SCOM MS
LogAlert.ps1 to verify SCOM notification account
New-SNowEvent.ps1 to inject events into ServiceNow
New-SNowIncident.ps1 to inject incidents into ServiceNow
Save LogAlert.ps1
Create Command channel script and save to SCOM MS(s)
SNOW Event command channel injects ServiceNow SNOW events, with logic to check for alert, incident, then update the SCOM alert TicketID, Owner, ResolutionState based on runtime.
SCOM Navigation steps:
Click on Administration Tab > Notifications > Channels
Click New
Name
ServiceNow SNOW Event Creation Channel
Use New-SNowEvent.ps1 to create SCOM subscription that creates SNOW incidents, then updates SCOM alert with TicketID, Owner, Resolution State for SCOM alert.
This command channel helps admins determine variables possible to pass to PowerShell script(s).

Time to ‘Test SNOW script’ for event or incident injection. As long as the prerequisites are verified, to include network connectivity, URL, ID, Password, etc., we’re ready to go!
Once the CredentialManager piece has been completed, by the same token you can begin testing the script. Testing can begin, whether to the SCOM Admin SA account, or to the SCOM Notifications account, or even hard coding the values into your PowerShell session.
Begin script testing
The testing leverages that you’ve downloaded various integration scripts first, then being saved on SCOM MS (management servers). The following blog posts, GitHub repo’s will set up multiple methods to test from PowerShell (command line) as SA or SVC accounts.
New-SNOWEventPowerSHellOutput for REST Event injection.
Verify SCOM alert updated for ServiceNow REST injection
Check SCOM console/web console for SCOM alert updates to ResolutionState, TicketID, Owner fields, where TEAM = SYM, and Assignment Group = JustinTime Infra specified
SCOM Monitoring tab Active Alerts output view showing Owner, ResolutionState, and TicketId fields updated.
Be aware of issues
Indicator of Certificate/trust issue
Invoke-RestMethod error seen when organization cert not installed, making server sending REST injection NOT trusted.
Indicator when SNOW alert rule not configured or matching – excessive retry’s. Also note output shows summary of tests, ServiceNow SNOW detail, and SCOM alert updates.
New-SNOWEvent.ps1 failures when SNOW Alert rule not matching or created.
Logging to Operations Manager Event Log for addtional troubleshooting or debug. Unless otherwise updated, the script logs to the ‘Operations Manager’ event log, EventID = 710-712
Single Starting event indicates failed pre-requisite (pre-req NOT met)
SCOM OperationsManager events logging integration script status, as well as whoami and additional debug.
