    @Shiva Ravichandran , From your description, I know the MonitoringHost.exe consumes high CPU on SCOM Gateway server with Windows Server 2008 R2 Version. If there's any misunderstanding, please let us know.

    For windows server 2008 R2, there's some known issue with CPU. we can see if it met our situation:
    https://support.microsoft.com/en-us/topic/operations-manager-agents-consume-100-percent-of-cpu-resources-for-the-monitoringhost-exe-process-a0523d63-aead-a4cf-0a29-387b7147ed49
    https://support.microsoft.com/en-us/topic/the-monitoringhost-exe-process-may-consume-all-the-cpu-resources-when-a-large-amount-of-performance-data-is-created-by-using-a-managed-data-source-module-in-system-center-operations-manager-2007-02b514c3-9c69-a2ab-d03c-63f4d177c4a3

    However, if it is not, could you collect the following information to clarify?

    1. Could you let us know the SCOM version?
    2. When did this issue happen? Have we changed anything before the issue occurring? Have we imported any new MPs?
    3. Check the Operations Manager event log during the high CPU time to see if there's any finding.

    Meanwhile, we suggest to install all the latest hotfixes for the Windows 2008 R2 server and clear cache to see if it can help.

    As pre Crystal mention, there is a known issue in early version of SCOM. As a result, please update the latest CU for your SCOM environment and also apply latest update on windows environment. Moreover, i want to know more detail information for this

    1. what is the version of SCOM
    2. any error log in event log
    3. on agent machine
      Stop Microsoft monitoring agent service
      Remove the folder %systemdrive\Program Files\Microsoft Monitoring Agent\Agent\Health Service State
      Restart Microsoft Monitoring agent service
