Agent proxy

Posted by MarcKlaver on July 1, 2011

Until now we have set the Agent proxy for an agent only when required and we used a script to do this. See this link for more information. But now Microsoft has come up with something new in the Exchange 2010 management pack. It will not discovery anything until you have set the agent proxy on for the Exchange servers (so we can’t do this afterwards anymore). So this meant for us we need to make a choice:

  1. Manually enable the proxy agent setting for all Exchange 2010 servers (now and in the future). Which means an Exchange 2010 server will not be discovered until we actually do.
  2. Enable the proxy agent for all agents.

Counting at the moment around 60 percent of the agents already has the proxy functionality enabled. So what’s the advantage of not setting this setting on default for all agents? Looking at security, you have to enable this setting already for all security important servers (AD, Exchange, ISA, Citrix, etc.). And since we have no knowledge of when an Exchange server is connected to our environment, we decided to enable it for all agents.

This is the script to do it:


# Add operations manager snapin and connect to the root management server.
add-pssnapin "Microsoft.EnterpriseManagement.OperationsManager.Client";
set-location "OperationsManagerMonitoring::";
new-managementGroupConnection -ConnectionString:$rootMS;

## set proxy enabled for all agents where it is disabled
$NoProxy = get-agent | where {$_.ProxyingEnabled -match "False"}
$NoProxy | foreach {$_.ProxyingEnabled = $true}
$NoProxy | foreach {$_.ApplyChanges()}
