Exchange 2007 and 2010 which log files are collected

[bohrasaurabh]

Is there a list of all the log files which are collected on different type of exchange servers CAS, Mailbox and Hub Transport.

Also I would like to know what is the compression ratio of these files.

Thanks,

From the config files for the TAs:

[monitor://C:\Program Files\Microsoft\Exchange Server\V14\TransportRoles\Logs\MessageTracking]
whitelist=.log$|.LOG$
sourcetype=MSExchange:2010:MessageTracking
queue=parsingQueue
index=msexchange
disabled=false

[monitor://C:\inetpub\logs\LogFiles\W3SVC1*.log]
sourcetype=MSWindows:2008R2:IIS
queue=parsingQueue
index=msexchange
disabled=false
ignoreOlderThan = 24h
crcSalt =
_TCP_ROUTING = New_Splunk_Indexers

So Message Tracking and IIS logs are the primary log types. There is also a Powershell script that collects admin logs (if you have those enabled in your environment). Note that other statistics are collected through perfmon and scripted inputs, so your total consumed volume will be higher than that.

Compression ratio depends entirely on your environment - Splunk will typically tell you to expect an average compression ratio of 0.5, but this all depends on your data. In our environment, it's typically about twice as good as that; that is, we see compression ratios from 0.25.
