4.3.2 Defining measurement conditions

You use PFM - Web Console to define measurement conditions for measuring an Internet service in the measurement condition registration file (esptask.xml) (or you can edit the file directly and define the conditions).

This subsection describes the Internet services that can be specified as measurement targets, the measurement items, and how to create a measurement condition registration file.

Organization of this subsection

(1) Measurement target and measurement items
(2) Creating the measurement condition registration file (esptask.xml)

(1) Measurement target and measurement items

The following table lists the standard Internet services supported by PFM - Agent for Service Response and the measurement items for each service.

Table 4‒2: List of measurement target services and measurement items
Measurement target service	Measurement items
HTTP	Total response time Setup time HTTP time DNS time TCP connection time Server processing time Data transfer time Total amount of data Number of requests Total size of resources Throughput
HTTPS	Same as the HTTP measurement items
SMTP	Total response time Setup time SMTP time DNS time TCP connection time Preprocessing time Data transfer time Total amount of data Throughput
POP3	Total response time Setup time POP time DNS time TCP connection time Preprocessing time Data transfer time Deletion time Total amount of data Total size of emails Number of downloaded emails Throughput
IMAP4	Total response time Setup time IMAP time DNS time TCP connection time Preprocessing time Data transfer time Deletion time Total amount of data Total size of emails Number of downloaded emails Throughput
DNS	Total response time Total amount of data
DHCP	Total response time Address presentation time Address acquisition time Total amount of data
FTP	Total response time Setup time FTP time DNS time TCP connection time Preprocessing time Data transfer time Size of transferred file Total amount of data Throughput
TCP	Total response time DNS time TCP connection time

For details about the measurement items for each service, see 10. Records.

(2) Creating the measurement condition registration file (esptask.xml)

To specify measurement conditions for the target Internet services, you must create a measurement condition registration file (esptask.xml). You can define measurement condition registration file in PFM - Web Console. The measurement condition registration file contains settings common to all services, as well as settings specific to individual services.

The following table lists and describes the settings that are common to all services.

Table 4‒3: List of measurement condition items (common to all services)
Item	Description
Measurement condition ID	Specifies an identifier for the measurement condition. Each measurement condition ID must be unique.
Measurement interval	Specifies a measurement interval.
Timeout	Specifies the timeout value for each measurement.
Service-specific conditions	Specifies definitions for the target service.

The items common to all services include settings such as the measurement interval and a timeout value for the target service. Measurement conditions are managed by the measurement condition IDs. You can register the same measurement condition for the same target service under different measurement condition IDs in order to treat them as separate measurement conditions. For details about the service-specific settings and the measurement condition registration file, see 8.3 Measurement condition registration file (esptask.xml).

You save the created measurement condition registration file in the following folder:

Measurement condition registration file storage folder:: installation-folder\agtv\probe\task\esp
