Exchange Storage Groups Test

An Exchange storage group is a logical container for Exchange databases and their associated system and transaction log files.

This test monitors the mailboxes in a storage group to report key statistics such as the number of mailboxes that have exceeded their storage limit, the number of mails in the mailboxes, etc.

Target of the test : A server configured with the Mailbox server role

Agent deploying the test : An internal agent

Outputs of the test : One set of results every storage group auto-discovered from the Mailbox being monitored.

Configurable parameters for the test
Parameters	Description
Test Period	How often should the test be executed.
Host	Indicates the IP address of the Mailbox server.
Port	The port number through which the Mailbox server communicates. By default, this is 6001.
XchgeXtensionShellPath	The Exchange Management Shell is a command-line management interface, built on Windows PowerShell which enables you to administer every part of Microsoft Exchange. This test uses the Exchange management shell to run scripts and collect the desired performance metrics from the Exchange server. By default, the test auto-discovers the location of the Exchange management shell and thus, automatically loads the Exchange management shell snap-in (exshell.psc1) for script execution. This is why, the XchgeXtensionShellPath is set to none by default.
Detailed Diagnosis	To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled: The eG manager license should allow the detailed diagnosis capability Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Disconnected users	Indicates the number of users who are currently disconnected from their mailboxes in a storage group.	Number
Users with storage limit warning status	Indicates the number of users whose mailboxes are currently reaching their storage quota and are therefore receiving the storage quota warning message.	Number	A storage quota is a storage size limit for a mailbox or a public folder. You can use the Exchange Management Console or the Exchange Management Shell to view or set the storage quotas for all of the mailboxes or public folders in a database. You can also use the Exchange Management Console or the Exchange Management Shell to set storage quotas on a per-mailbox basis, thereby overriding the storage quotas that are set at the database level. However, storage quotas for individual public folders can be viewed or set only in the Exchange Management Shell. If a mailbox size reaches or exceeds the Issue warning value that has been configured for a mailbox/database, then Exchange will automatically send a warning message to that mailbox. A non-zero value for this measure therefore, indicates that one/more mailboxes in the storage group are in danger of exceeding their storage quota. You can use the detailed diagnosis capability of this measure to identify the mailboxes that might be fast exhausting their storage quota. Based on the detailed diagnosis, you can decide whether to revise the storage quota or clear unnecessary mails from the listed mailboxes to make more space therein.
Users with storage limit prohibit status	Indicates the number of users whose mailboxes have reached their storage quota currently and hence, will not be able to send any emails.	Number	If a mailbox size reaches or exceeds the limit specified against Prohibit send at, Exchange will prevent that mailbox user from sending new messages and will display a descriptive error message. A non-zero value for this measure is a cause for concern, as it indicates that one/more users might not be able to send out critical mails from their mailboxes. Use the detailed diagnosis of this test to identify the affected users, and then decide whether to increase the Prohibit sent at limit or simply remove unnecessary mails from the users’ mailboxes to make space available.
Total number of mails	Indicates the current number of e-mails in all mailboxes homed in a storage group.	Number
Total mail size	Indicates the total size of all mailboxes homed in this storage group.	MB
Total deleted mails	Indicates the number of deleted e-mails currently in all mailboxes homed in a storage group.	Number
Total deleted mail size	Indicates the current size of all deleted e-mails in all mailboxes homed in a storage group.	MB
