The article helps to understand different counter on Mailbox and Client Access Server role in Exchange 2013 Server. I have exported in the spreadsheet divided into
1. Common Counters in Mailbox and Client Access Server Role
2. Unique Counters present only in Client Access Server Role
3. Unique Counters present only in Mailbox Server Role
You can download them on clicking Exchange_2013_Perfmon_Counters
The powershell command used to get this report – Get-Counter -ListSet *msexchange* | Select-Object -ExpandProperty Counter and then played excel to make easier to understand.
