Outlook Web Access Test

Outlook Web Access (OWA) is a HyperText Transfer Protocol (HTTP) virtual server that enables users to access their Microsoft Exchange inbox using a Web browser. In the event that users are unable to access their mailbox, you can use the metrics reported by this test to determine whether the problem in HTTP access is local to the client access server or not.

Target of the test : An Exchange 2007/2010 server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for the Client Access server 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 Client Access server.

Port

The port number of the client access server. By default, this is 110.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Outlook web access sessions

Indicates the number of Outlook Web Access user sessions that are created per second.

Login/Sec

 

Current unique web access users

Indicates the number of unique users currently logged on to Outlook Web Access.

Number

This value monitors the number of unique active user sessions, so that users are only removed from this count after they log off or their session times out.

Response time for web access - average

Indicates the average time in seconds that elapsed between the beginning and end of an OEH or ASPX request.

Secs

This is a good measure of the latency that a client is experiencing.

Higher values may indicate high user load or higher than normal CPU time.

Search time during web access - average

Indicates the average time that elapsed while waiting for a search to complete.

Secs

Ideally, this value should be low at all times.

Request rate for web access

Indicates the number of requests handled by Outlook Web Access per second.

Reqs/Sec

 

Failed requests for web access

Indicates the number of Outlook Web Access requests that failed, per second.

Reqs/Sec

A zero value is typically desired. If the measure reports a non-zero value, the reason for the same should be investigated.

Store logon failures for web access

Indicates the percentage of Outlook Web Access user logons to Microsoft Exchange Mailbox servers that have failed currently.

Percent

Ideally, this value should be low.
