Install Guide

a. Copy DellEMC-SCOM-Agent-Registry.reg and DellEMC-Proxy-MS-Configuration-Script.ps1 files from the extracted

location on each of the Proxy MS machine in the same directory.

b. Run the DellEMC-Proxy-MS-Configuration-Script.ps1 from the PowerShell command prompt (with administrator privileges).

NOTE:

• The script stops the agent health services, takes a backup of current registry values in the same directory path.

• The required Registry Key changes are implemented on the Proxy MS. See the table below for registry

configuration on Proxy MS

• Microsoft Monitoring Agent Health Services are started.

• Registry Path: "HKLM\SYSTEM\CurrentControlSet\services\HealthService\Parameters"

S.No. Registry Configuration

1 Set the Persistence Version Store Maximum Registry Path to 131072.

2 Set the Maximum Global Pending Data Count Registry to 20408.

3 Set the State Queue Items Registry to 20480.

4 Set the Persistence checkpoint Depth Maximum Registry to 20971520.

NOTE: For more information about the registry key settings, see https://blogs.technet.microsoft.com/.

CAUTION: Using Registry Editor incorrectly can cause serious problems that might require you to reinstall the

operating system.

NOTE: The above sample script is provided to simplify configuration of the above required settings on the Proxy MS.

Dell EMC does not officially support this script.

3. The Microsoft public hotfix https://support.microsoft.com/en-us/help/4481376/must be applied on each of the Systems Center

Operations Manager Servers and on every Proxy MS in the Scalability setup.

NOTE:

On the Proxy MS, locate SnmpModules.dll in C:\Program Files\Microsoft Monitoring Agent\Agent

\SnmpModules.dll.

Recommendations:

Here are few recommendations that are taken care of for Proxy MS:

1. You can check for number of devices that you want to monitor and create Proxy MS accordingly. Each Proxy MS can monitor

maximum of 250 devices in scalable mode or 30 devices in detailed mode.

2. Maximum number of Proxy MSes that can be added to a Management server is less than or equal to four.

3. Symmetrically distribute the Proxy MSes across all the Management Servers in the resource pool.

4. Ensure not to overload Management Servers by adding more number of proxy MS. The safe limit for a Management Server is to

monitor maximum of 1000 devices in scalable mode or 60 devices in detailed mode using Proxy MSes.

• When you add Proxy MS in the Operations Manager group Dell ProxyMSGroup, perform synchronization to apply the required

configuration changes in the Proxy MS agent. For more information, see Synchronizing Dell Proxy MS with OMIMSSC and

adding ProxyMS to DellProxyMSGroup in Dell EMC OpenManage Integration for Microsoft system Center Version 7.1.1

Operations Manager User's Guide.

Adding Proxy MS to DellProxyMSGroup and

Synchronizing Dell Proxy MS with OMIMSSC

During enrollment, a group that is named DellProxyMSGroup is created. Proxy management servers that are discovered in Operations

Manager console as an Agent Managed Windows computer, are required to be added to the group DellProxyMSGroup into the

Operations Manager console, and perform synchronization of Proxy MS with OMIMSSC.

NOTE: Ensure that you install Operations Manager Agents on all Proxy MS before performing the below steps.

To add the DellProxyMSGroup, perform the following steps:
