Deploying System Center 2012 – Operations Manager

Single-server management group installation

The single-server management group scenario combines all the management group roles that can coexist onto a single instance of the Windows Server 2008 R2 SP1 operating system running as a member server in an Active Directory domain. This instance can be on dedicated hardware or on a virtual computer. The Operations console can be deployed to computers other than the single server, and the web console is accessed via a browser.

Available Operations Manager Services in Single-Server Deployment

  1. The single-server management group configuration supports the following services:
  2. Monitoring and alerting
  3. Reporting (available in the Operations console but not in the web console)
  4. Audit collection
  5. Agentless exception management
  6. Data (accessed by using the web console and the Operations console)


The single-server management group configuration is the easiest to deploy, but there are limitations to its capabilities and therefore limitations to what it is commonly used for.

High Availability and Redundancy

The single server, single management group resides on a single set of hardware. This configuration supports only one instance of each server role and therefore cannot support agent failover between management servers.

Gateway Server

This configuration does not include the gateway server role. Because of this, all monitored devices must be in the same Active Directory domain as the management server or you must use certificates on both the managed computer and the management server to provide for mutual authentication.

Distributed management group installation

The distributed management group installation will form the foundation of 99 percent of System Center 2012 – Operations Manager deployments. It allows for the distribution of features and services across multiple servers to allow for scalability and also provides availability. It can include all Operations Manager server roles and supports the monitoring of devices across trust boundaries through the use of the gateway server.

The following diagram presents one possible option for the distributed management group topology

System Center 2012 – Operations Manager Cross Platform Visibility

Microsoft System Centre Operations Manager 2007 introduced Distributed Application Models and Synthetic Transactions as part of extending the visibility of monitoring solution.  In the later version, SCOM 2007 R2, Microsoft enhanced the visibility by introducing Cross Platform Monitoring.  The cross platform monitoring provided the ability to monitor non-Microsoft operating system such as HP-UX, AIX, Linux and Solaris.

The introduction of native network monitoring and .NET / J2EE Application monitoring support in SCOM 2012 provides the ability to capture all components within your networks that are part of providing services to the users.

Following diagram represents the Components, Applications and  Operating System platforms  monitored out of the box through system Centre 2012 – Operations Manager.

More about network monitoring capabilities:

SCOM 2012 includes significant new network monitoring capabilities that make it a much more comprehensive monitoring solution for network admins. Some basic features have been present in older versions, but SCOM 2012 expands on these capabilities.

Following features are Included in SCOM 2012 out of the box:

  1. Network device discovery, monitoring and reporting
  2. SNMP v3 support. Previous versions of SCOM supported SNMP v1 and v2.
  3. IPv4 and IPv6 support
  4. Port/interface monitoring which includes: Up/down monitoring, Traffic volume, Utilization, Dropped packet rate, Broadcast traffic stats etc..
  5. VLAN health monitoring (Auto discovery of all the VLANs)
  6. Overall connection health
  7. Hot Standby Router Protocol (HSRP) group health
  8. New visualization/dashboards which includes : Overall network health summary, The health of a device on the network, its  interface-level statistics, its neighbors and connected windows servers monitored by SCOM etc..

    Great overview of SCOM 2012!! I’m new to SCOM, so this may be a very basic question. I was told Service Manager is needed to take advantage of SCOM. We have a different ITSM solution, so I do not want to install Service Manager. We just need to do monitoring of our server, DB, network, etc… Can I use SCOM without SM?

    • System Center Service Manager is a Microsoft ITSM solution. SCOM integration with SCSM will enable you to create tickets automatically at the event of any alerts.
      You do not require SCSM to monitor your servers, DBs, network, etc… SCOM alone can fulfill your requirements.
      however, if your existing ITSM solution has connector available to integrate with SCOM, you can leverage the same instead of SCSM.
