2.2 Selecting the type of measurement for Web server monitoring
If you want to monitor your Web server using PFM - Agent for Service Response, select the type of measurement from:
-
Measurement of Internet services (HTTP or HTTPS)
-
Measurement of Web transactions
-
Measurement of IE scenarios
If you want to monitor only the operating status of a monitored server or monitor a single Web page (for example, to monitor the top page only), you can use the type of measurement of Internet services (HTTP or HTTPS). This measurement is available with simple definition information compared with the measurement of Web transactions or of IE scenarios.
If you want to monitor transition and response performance of several Web pages, use the measurement of either Web transactions or IE scenarios. The table below shows the difference between measurement of Web transactions and measurement of IE scenarios.
|
Item |
Web transactions |
IE scenarios |
|---|---|---|
|
Measurable response performance |
If you use the Web transactions, you can measure the amount of the time it takes to communicate with the Internet services (HTTP(S), DNS, or the like) as the response performance. |
If you use IE scenarios, you can measure the elapsed time between the time you perform operations in Internet Explorer and the time these operations are completed as the response performance. You can monitor the approximate response performance to the ones users feel when operating in Internet Explorer. |
|
Password management |
The passwords are not managed in the Web transaction files but in the password file. |
The passwords are managed in the IE scenario files. |
|
Scope definitions |
The scope of the Web transactions is a series of skips (a skip is a unit of the HTTP request and its HTTP response). |
The scope of the IE scenarios is a series of operations in Internet Explorer. |
|
Response determination |
You can define a condition or a combination of two or more conditions as a response determination condition. |
You can define a condition or a combination of two conditions as a response determination condition. |
|
Acquisition of embedded resources |
You must define in the transaction files whether or not the embedded resources are acquired. |
Internet Explorer acquires the embedded resource automatically. |
|
Support for dynamic session management |
You must analyse the dynamically changing information and define necessary information to process dynamic session. |
Internet Explorer processes automatically. |
|
Specification of the character set |
You must define the character set in the Web transaction files. |
Internet Explorer processes automatically. |
The measurement of IE scenarios depends heavily on the specifications of Microsoft Internet Explorer. Therefore, some Web pages cannot be measured depending on these specifications. Hitachi recommends that you use the trial version of PFM - Agent for Service Response and check to see if the software can measure monitored Web pages successfully before using the product version. For details about Web pages that cannot be measured in the measurement of IE scenarios, see 5.2.3 Notes on IE scenarios and 5.2.4 Notes on the navigation.
