Exchange 2010 documentation-Load Balancers and Mail Devices (Ironport, Barracuda)

Looking to get exchange documentation for a 2010 environment

There are 2 CAS , and the same are used as HUB Transport Servers

3 Mailboxes, 1 Unified Messanging Role, Have documented through scripting

Use of Ironport C170 , Barracuda Spam Firewall 300 and Enterprise Vault as well

Is there a handy way to check load balancing, I want to see if its set up through CAS Array, whats best way to check this and interaction with Ironport, Barracuda etc to generate mailflow diagrams?

Hi Indie101,
Even if you have only one CAS server it is recommended to have a CAS Array.
If you have more than 1 CAS server create a CAS Array and with FQDN
Create an A record with a new IP and configfure that IP as the virtual server IP in ironport.

Please read this as well for understanding more about CAS Array.

You need to configure CAS Counter using Perfmon. Then review the data.

I do this way:
Get-Counter "MSExchange Availability Service\Availability Requests (sec)","MSExchange Availability Service\Average Time to Process a Free Busy Request","ASP.NET\Application Restarts","ASP.NET\Worker Process Restarts","ASP.NET\Request Wait Time","ASP.NET Applications(*)\Requests In Application Queue","MSExchange ActiveSync\Ping Commands Pending","MSExchange ActiveSync\Sync Commands Pending","MSExchange ActiveSync\Current Requests","MSExchangeAutodiscover\Requests/sec","MSExchangeWS\Requests/sec","\W3SVC_W3WP(*msexchangeservicesapppool)\Active Requests","\Netlogon(_Total)\Semaphore Timeouts","Web Service(_Total)\Current Connections" -ComputerName Servername | Export-Counter -Path c:\temp\counter.csv -FileFormat csv

For Hub you can review protocol logging. I parse it with below command, like below example for Active Sync load balance:
Export-ActiveSyncLog -Filename: "C:\inetpub\logs\LogFiles\W3SVC1\u_ex180409.log" -StartDate:"04/08/18" -EndDate:"04/09/18" -UseGMT:$true -OutputPath:"c:\temp"

Other way is to review your HLB logs.

if you are looking for anything online, don't waste your time.
