SunOne Http Test

This test measures the health of the virtual server configured for the Sun Java System Http server.

Target of the test : Any Sun Java System application server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every virtual server configured for the web server.

Configurable parameters for the test
Parameter Description

Test period

How often should the test be executed

Host

The host for which the test is to be configured.

Port

The port number on which the Sun Java System application server is running.

User

A valid user name for the Sun Java System server to be monitored.

Password

Password for the Sun Java System server to be monitored.

Admin Port

The port number on which the “asadmin” tool runs.

Server

Name of the Sun Java System server to be monitored.

AppServerDir

The directory in which Sun Java System application server is installed.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Request rate

Rate of requests to the web server during the last measurement period.

Reqs/Sec

This measure reflects the server workload.

Data received

Rate at which the data is received by the server during the last measurement period

KB/Sec

 

Data transmitted

Rate at which the data is transmitted by the server during the last measurement period.

KB/Sec

 

Data transmit high watermark

The high-water-mark of the data transmit rate by this server

KB

 

Open connections

Number of server threads/processes currently in use for serving requests

Number

Ideally, this measure must be low. Too many server threads or processes serving user requests could indicate a server-side bottleneck – either with the web server itself or with one of the backend components that the web server uses (e.g., database server).

Open connections high water mark

The high-water-mark of the open connections count

Number

Changes in the high water mark are indicative of times when the server has been a performance bottleneck. Note that the high water mark value gets reset every time the server is restarted.

200 responses

Percentage of responses with a status code in the range of 200-299 during the last measurement period

Percent

 

300 responses

Percentage of responses with a status code in the range of 300-399 during the last measurement period

Percent

 

400 errors

Percentage of errors with a status code in the range of 400-499 during the last measurement period

Percent

 

500 errors

Percentage of errors with a status code in the range of 500-599 during the last measurement period

Percent

 

Other responses

Percentage of responses with a status code that is greater than or equal to 600 during the last measurement period
