Create an Exchange Server List
To scope out your MessageStats deployment, you need information about your Exchange organization topology, and about the network latency between your Exchange servers and the servers that will host the MessageStats data collectors.
Create a list of your Exchange servers, showing the server functions and physical geography. (To determine the location of the Exchange servers, you can use the Microsoft Exchange Administrator.)
Determine Exchange Server Latency
Once you have a list of Exchange servers, collect ping statistics and server connectivity details from your Exchange servers to the following:
This information will assist in determining the optimal locations of the MessageStats Scheduler Server and of the Task Execution Servers.
Estimate the Exchange Tracking Log Sizes
For each Exchange server in the list, verify that Exchange tracking is turned on and that the tracking log folder is shared. The default location of the folder is as follows for the various releases:
Exchange servers usually keep seven days of tracking logs. A week's amount of log files can provide a reliable average per server.
Use this information to obtain insight about the disk space needed on each Task Execution Server to analyze and process all the tracking logs. This information also helps to decide whether to use the MessageStats tracking log compression utility to reduce network traffic.
Identify Data Collection and Storage Requirements
Data requirements are affected by two considerations:
This information can assist in estimating the storage requirements. You can use the MessageStats database size estimation tool which is available from the Support portal at https://support.quest.com/.
MessageStats can collect a number of Microsoft Exchange object characteristics, some of which you can exclude from the gatherings.
In addition to the Exchange core information that is gathered by a Default Gathering task, information that can be gathered includes: distribution group membership, detailed audit information, and public folder information.
To estimate the storage capacity that is needed on the SQL Server that hosts the MessageStats database, you need to know how much historical reporting is required. By retaining historical information, you can use MessageStats to view trend and forecast information for your Exchange organization.
