So you can quickly respond to any issues found with different options. One of the things that will help you in troubleshooting any issues — is Secure Channel verbose logging. Remember to set this back to 1 when done resolving any issues. I have written solutions that include tasks to add and remove management group assignments to SCOM agents before:. But, what if you are doing a side by side SCOM migration to a new management group, and you have thousands of agents to move?
There are a lot of challenges with that:. It contains one disabled rule, which will multihome your agents to your intended ManagementGroup and ManagementServer. This is also override-able so you can specify different management servers initially if you wish:.
This rule is special — in how it runs. It is configured to check once per day seconds to see if it needs to multi-home the agent. If it is already multi-homed, it will do nothing. If it is not multi-homed to the desired manaement group, it will add the new management group and management server. But what is most special, is the timing. Once enabled, it has a special scheduler datasource parameter using SpreadInitializationOverInterval.
This is very powerful:. What this will do, is run once per day, but the workflow will not initialize immediately. It will initialize randomly within the time window provided. In the example above — this is seconds, or 4 hours.
This means if I enable the above rule for all agents, they will not run it immediately, but randomly pick a time between NOW and 4 hours from now to run the multi-home script. This keeps us from overwhelming the new environment with hundreds or thousands of agents all at once.
You can even make this window bigger or smaller if you desire by editing the XML here. If you multi-homed all of these to a new management group at once, it would overwhelm the new management group and take a very long time to catch up. You will see terrible SQL blocking on your OpsMgr database and events about binding on discovery data while this happens. The idea is to break up your agents into groups, then override the multi-home rule using these groups in a phased approach.
You can start with agents over a 4 hour period, and see how that works and how long it takes to catch up. Then add more and more groups until all agents are multi-homed. These groups will self-populate, dividing up the number of agents you have per group. They query the SCOM database and use an integer to do this. By default each group contains agents, but you will need to adjust this for your total agent count. Also note there is a sync time set on each group, about 5 minutes apart.
This keeps all the groups from populating at once. You will need to set this to your desired time, or wait until 10pm local time for them to start populating. Agents that are down or in maintenance mode will multi-home when they come back up gracefully. Using the groups, you can control the load placed on the new management group and test the migration in phases.
Using the groups, you can load balance the destination management group across different management servers easily. This monitor was very noisy in previous versions of this MP. Changes made: This now ships disabled out of the box. If you want to accurately monitor for time synch on Windows Server and later, enable this monitor. This monitor previously had a VERY strict threshold of 1ms. The default threshold is now 60, milliseconds 60 seconds.
You should set this value to what would be actionable in your environment for time sync. In general, collecting events is a bad practice.
Many customers have been impacted by event storms, that fill the OpsDB and consume massive amounts of space filling their Data Warehouse, for almost zero value. Now, all rules that only collect events not alert on them have been disabled out of the box. If an event is important, it should generate an alert. Otherwise, if it is not actionable, it becomes noise, bloat, or at worst: takes down your SCOM environment.
You can overwhelm a DW very quickly with this MP if you just turn this on blindly. In general, I recommend you test and experiment with this new style of Process monitoring in a lab environment, and not bring this specific MP Microsoft. There are some other enhancements and fixes as well, documented in the MP guide…. A common issue I find in customer environments, is that they do not set their agents to be able to fail over to multiple Gateways, or they do not set their Gateway servers to be able to fail over to multiple management servers.
You should always configure Gateway Failover otherwise you will issue hundreds or thousands of Heartbeat failures should you ever take the Management Server down for planned or unplanned maintenance. It will also gather important information, like if the workflows generates an alert or not, and the details of the alert like default priority and severity. In the past we would use tools like Telnet, or Portqry to test port connectivity, but often this is not installed and not easily available.
Luckily, we always have PowerShell! Here is a quick and dirty PowerShell script you can run as a single line, to test name resolution and port availability.
Customer is migrating agents from a complex environment into new management groups. Before they did this — they wanted to ensure that agents were not firewalled off from the new management servers. This can be a monumental task in large environments, especially with unique gateway and firewall deployments. I have added a discovery which will handle this scenario to the SCOM. Management MP available here:.
In the SCOM. This will do a port check on from the agent to each management server or gateway in this list, and report back in a class property, and another property to gather the IP address of the agent, to make quick work of new firewall requests you might have to make:.
We saw many improvements using controls based on group, class, specific rule or monitor, along with other criteria:. However — the Product Connector subscription wizard was never updated.
This is unfortunate, because both product connectors and email notification subscriptions are actually identical behind the scenes. The modules behind the scenes are the same: Microsoft. While more time consuming — you can use the same criteria and expressions in product connectors, as you would in an email notification. Internal MP Notifications Internal Library , and copy the expressions over to your product connector subscriptions. Then simply increment your notifications internal library MP version, and reimport.
Always save a backup first! Specific instance of a class raised by a single specific instance of a specific class :. Note: Keep in mind, just like many times when you edit the XML directly in a way not supported by the UI — you can no longer use the UI to edit these subscriptions.
You can delete them using the UI however. There is a registry entry used to decrypt these, and this is generated when the first management server is installed. This is normally copied to new management servers as they are added after the first MS in a management group.
If they are, Setup will contact them, and copy the registry entries needed to deal with RunAs account decryption. However, if ALL management servers have been lost, then it will re-generate a new decryption key, but this results in you having to re-enter your existing RunAs account passwords in SCOM once the recovery action is complete.
The default is any agent that generates 50 alerts, in a 60 second window — will auto-disable that workflow for 10 minutes to control alert storms. All of this activity occurs on the agent itself. Usually, when a rule generates this many alerts, it is because the rule definition is misconfigured. Please examine the rule for errors. In order to avoid excessive load, this rule will be temporarily suspended until T Rule: SCOM.
Alert Count - number of alerts from a single workflow to trigger an event about the alert storm. You will need to restart the Microsoft Monitoring Agent Healthservice on the agent, in order for these changes to take effect. You should only patch one management server at a time to allow for graceful failover of agents and to keep resource pools stable.
This is a known issue. Ignore it. Find it by scrolling through each one, the console will tell you if you already have the same version. This is a concept that I have seen several examples of, but realize not everyone knows of this capability.
You can create a rule, that targets a class hosted by an agent such as Windows Server Operating System , but have a script response run on the Management Server to take action. This is the key part:.
My example is very simple — and runs PowerShell on the Management server, creating a single simple event in the OpsMgr log. This design works in SCOM and later — where the response will execute on the Management Server that the agent is assigned to. You can use this example to do things, like query the OpsDB and generate a specific alert in response to an agent side issue — or you can put the agent into Maintenance mode by passing the computername as a parameter to the script write action.
Clusters contains virtual, abstract objects, that could be hosted by one or more nodes. We need to ensure we always monitor the clustered resource, no matter where it is running. We cannot simply target discovery and monitoring to the nodes, because by design the clustered resource will only exist on one node, then all other nodes would generate alerts. We start with a simple seed class discovery. Remoteable allows the nodes to discover for the virtual computers.
Try to use something specific to your application, such as the existence of a specific service registry for this discovery. This Windows Server class already has a property to know if the object is a cluster virtual object true or not empty. One of the first things we will pass to the script as a parameter, is the IsVirtualNode property. The script will only return discovery data for virtual objects.
There is a registry entry used to decrypt these, and this is generated when the first management server is installed. This is normally copied to new management servers as they are added after the first MS in a management group.
If they are, Setup will contact them, and copy the registry entries needed to deal with RunAs account decryption. However, if ALL management servers have been lost, then it will re-generate a new decryption key, but this results in you having to re-enter your existing RunAs account passwords in SCOM once the recovery action is complete.

For more information about how to set up, configure, and run your environment to use TLS 1. From reading the KB article — the order of operations is: Install the update rollup package on the following server infrastructure: Management servers Audit Collection servers Gateway servers Web console server role computers Operations console role computers Reporting Apply SQL scripts.
Manually import the management packs. The first thing I do when I download the updates from the catalog, is copy the cab files for my language to a single location then extract the contents: Once I have the MSP files, I am ready to start applying the update to each server by role. You can also spot check a couple DLL files for the file version attribute: Next up — run the Web Console update: This runs much faster. A quick file spot check: Lastly — install the console update make sure your console is closed : A quick file spot check: Additional Management Servers: I now move on to my additional management servers, applying the server update, then the console update and web console update where applicable, just like above.
On any Audit Collection Collector servers, you should run the update included: A spot check of the files: Updating Gateways: I can use Windows Update or manual installation. The update launches a UI and quickly finishes.
You MAY be prompted for a reboot. See the KB article for more details. You can update this RDL optionally if you use that type of reporting and you feel you are impacted. If you see a warning about line endings, choose Yes to continue. Manually import the management packs There are 60 management packs in this update! I import all of these shown above without issue. You can now do this straight from the console: You can input credentials or use existing RunAs accounts if those have enough rights to perform this action.
Finally: Update the remaining deployed consoles This is an important step. Known issues: See the existing list of known issues documented in the KB article.
The errors reported appear as below: —————————————————— 1 row s affected 1 row s affected Msg , Level 13, State 56, Line 1 Transaction Process ID was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Cause: When we initially connect to the Web console, we check to ensure the client has a code signing certificate that matches the.
Known Workarounds: Manually handle the certificate distribution. When you are prompted to run or save the SilverlightClientConfiguration. Run the SilverlightClientConfiguration. Right-click the. In the dialog box that appears, click Install Certificate.
Select the Place all certificates in the following store option and then select Trusted Publishers. Click Next and then click Finish. Refresh your browser window.
Microsoft responded. This is a major change from all previous versions of SCOM. Longer term 5 years of mainstream support lifecycle. High Level Deployment Process: 1. Install Windows Server to all server role servers. Install the Management Server and Database Components 7.
Install the Reporting components. Deploy Agents 9. Import Management packs Set up security roles and run-as accounts Prerequisites: 1. Install Windows Server to all Servers 2. Join all servers to domain. Install all available Windows Updates. This document will not go into details and best practices for SQL configuration. Consult your DBA team to ensure your SQL deployment is configured for best practices according to your corporate standards.
Default instances are fine for testing, labs, and production deployments. Production clustered instances of SQL will generally be a named instance. For the purposes of the POC, choose default instance to keep things simple. You can accept the defaults for the service accounts, but I recommend using a Domain account for the service account. This will help performance when autogrow is needed. Alternatively, you can use the OMAdmins global group here.
This will install and configure SRS to be active on this server, and use the default DBengine present to house the reporting server databases. This is the simplest configuration. If you install Reporting Services on a stand-alone no DBEngine server, you will need to configure this manually.
Choose Install, and setup will complete. Run Setup. You might see an error from the Prerequisites here. If so — read each error and try to resolve it.
On the Proceed with Setup screen — click Next. On the specify an installation screen — choose to create the first management server in a new management group. Give your management group a name. Click Next. Accept the license. Leave the port at default unless you are using a special custom fixed port. If necessary, change the database locations for the DB and log files. Leave the default size of MB for now. On the Web Console authentication screen, choose Mixed authentication and click Next.
On the Diagnostic Data screen — click Next. Click Install. Close when complete. Before continuing it is best to give the Management Server time to complete all post install processes, complete discoveries, database sync and configuration, etc. Resolve any issues with prerequisites, and click Next. Accept the license terms and click Next. Select the correct database from the drop down and click Next.
Use Mixed Authentication and click Next. Locate the SCOM media. Select the following, and then click Next : Reporting Server Accept or change the default install path and click Next. Accept the license and click Next. Type in the name of a management server, and click Next. Choose the correct local SQL reporting instance and click Next.
Once you have SCOM up and running, these are some good next steps to consider for getting some use out of it and keep it running smoothly: 1. Fix the Database permissions for Scheduled Maintenance Mode The database permissions need to be edited to stop errors and allow Scheduled Maintenance to work. You can provide your license key during setup, or post installation using PowerShell. This is not a good setting for steady state as our databases will need to grow larger than that very soon.
We need to pre-grow these to allow for enough free space for maintenance operations, and to keep from having lots of auto-growth activities which impact performance during normal operations. Pre-size the Data Warehouse: You will need to plan for the space you expect to need using the sizing tools available and pre-size this from time to time so that lots of smaller autogrowths do not occur.
Set up SQL maintenance jobs. Be proactive. Configure Data Warehouse Retention. Enable Agent Proxy as a default setting I prefer to simply enable agent proxy for all agents. Backup Unsealed Management packs You need to set this up so that in case of a disaster, or an unplanned change, you will have a simple back-out or recovery plan that wont require a brute force restore of your databases.
This process has not changed from OpsMgr , so you would use the typical mechanism to push or manually install. Import management packs. Learn MP authoring. You might see these errors: Certificate Services Common Library could not be imported. Compatibility check failed with 4 errors: Error 2: Found error in 1 Microsoft. Active Directory Integration rules are not visible or editable in an upgraded Management Group. This prevents the ongoing management of Active Directory integration assignment in the upgraded Management Group.
Active Directory integrated agents do not display correct failover server information. Performance views in the web console do not persist the selection of counters after web console restart or refresh. Additionally, you receive the error message, "The management server to which this component reports has not been upgraded.
When you download a Linux management pack after you upgrade to SCOM , the error "OpsMgr Management Configuration Service failed to process configuration request Xml configuration file or management pack request " occurs. Please make sure Microsoft Word is installed. Here is the error message: Item with specified name does not exist" occurs. Accessing Silverlight dashboards displays the "Web Console Configuration Required" message because of a certificate issue.
Recommendations causes errors to be logged on instances of Microsoft SQL Server that have case-sensitive collations. Internal management pack. This monitor is no longer valid. Lets get started. My first server is a Management Server, Web Console server, and has the OpsMgr console installed, so I copy those update files locally, and execute them per the KB, from an elevated command prompt: This launches a quick UI which applies the update. This is a known issue. Ignore it. I will proceed with manual: The update launches a UI and quickly finishes.
Manually import the management packs There are 36 management packs in this update! Update the remaining deployed consoles This is an important step. Review: Now at this point, we would check the OpsMgr event logs on our management servers, check for any new or strange alerts coming in, and ensure that there are no issues after the update.
Known Issues: 1. Ok, warnings aside….. FullName, BME. DisplayName, BME. Path, dv. FullName, DiscoveryDisplayName. The Microsoft documentation for TLS 1. My first management server holds 3 roles, and each must be patched: Management Server, Web Console, and Console. The first thing I do when I download the updates from the catalog, is copy the cab files for my language to a single location, and then extract the contents.
My first server is a Management Server, Web Console server, and has the OpsMgr console installed, so I copy those update files locally, and execute them per the KB, from an elevated command prompt:. This launches a quick UI which applies the update. It will bounce the SCOM services as well. The update usually does not provide any feedback that it had success or failure….
Product Version: 7. Product Language: Manufacturer: Microsoft Corporation. Installation success or error status: 0.
You can also spot check a couple DLL files for the file version attribute. You should only patch one management server ata time to allow for graceful failover of agents and to keep resource pools stable. I will apply the update for that:. This is a known issue. Ignore it. I can also spot-check the AgentManagement folder, and make sure my agent update files are dropped here correctly:.
If you had previously applied this file in any other rollup, you MUST re-apply it now. If you are unsure if it was applied previously, you may always re-apply it. Reapplication will never hurt. Make sure it is pointing to your OperationsManager database, then execute the script. You should run this script with each UR, even if you ran this on a previous UR. The script body can change so as a best practice always re-run this. The execution could take a considerable amount of time and you might see a spike in processor utilization on your SQL database server during this operation.
I have had customers state this takes from a few minutes to as long as an hour. Do not continue. Try re-running the script several times until it completes without errors. In a production environment with lots of activity, you will almost certainly have to shut down the services sdk, config, and healthservice on your management servers, to break their connection to the databases, to get a successful run.
There are 36 management packs in this update! Only import the ones you need, and that are correct for your language. Only do this if it is blocking you from continuing.
