6 Scalability with Dell EMC OpenManage Integration with Microsoft System Center (OMIMSSC) for System Center
Operations Manager (SCOM)
1.4 Setting up Proxy MS to monitor multiple devices
1.4.1 Prerequisites for setting up Proxy MS for scaling up the number of monitored
devices
• Ensure that proxy management server is discovered as an agent-based computer on the SCOM
console.
• NOTE: Ensure that the proxy management server is hosted on a management server that is
part of the All Management Servers Resource Pool (AMSRP).
• Configure registry settings on the proxy management server.
• Apply Microsoft public hotfix: https://support.microsoft.com/en-us/help/4481376/ on each SCOM
server and on every proxy management server in the Scalability setup. On the proxy management
server, locate SnmpModules.dll in C:\Program Files\Microsoft Monitoring
Agent\Agent\SnmpModules.dll.
1.4.2 Recommendations to configure Proxy MS
• You can check for number of devices that you want to monitor and create proxy management server
accordingly. Each proxy management server can monitor a maximum of 250 devices in scalable
mode or 30 devices in detailed mode.
• Note: In the scalable mode of OMIMSSC, inventory and health monitoring details are
displayed up to the device and component group level. However, in the detailed mode of
OMIMSSC, inventory and health monitoring details are displayed for individual components
such as memory, processors, Compute Usage Per Second (CUPS), BIOS, and sensors in
addition to the group level details.
• Maximum number of proxy management servers that can be hosted on a single management server
is four in scalable mode and two in detailed mode.
• Symmetrically distribute the proxy management server across all the management servers in the
resource pool.
• Ensure not to overload management servers by adding a greater number of proxy management
servers. When using proxy management server, the safe limit for a management server is to monitor
a maximum of 1,000 devices in the Scalable mode or 60 devices in the Detailed mode.
1.4.3 Configure registry settings on the proxy management server
1. After extracting the OMIMSSC_<Version>.A00_SCOM.zip file, do the following:
Copy DellEMC-SCOM-Agent-Registry.reg and DellEMC-Proxy-MS-Configuration-Script.ps1
files from the extracted location on each of the proxy management server in the same directory.
Run the DellEMC-Proxy-MS-Configuration-Script.ps1 script from the PowerShell CLI (by using
administrator privileges).
• NOTE: The above sample script is provided to simplify configuration of the above required
settings on the proxy management server. Dell Technologies does not officially support this
script.
