Configuration of ApacheNSStatTest

This test reveals critical performance and uptime statistics pertaining to an Apache web server. This test, upon execution, accesses a specific URL on the Apache server, which contains the required metrics. Using this test, administrators can figure out how well the processes are being procesed in the server, how many processes are currently idle, the processes that are in KEEPALIVE and Logging state etc. This way, this test helps administrators to identify processing bottlenecks, if any.

The default parameters associated with this test are:

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• Specify the host for which the test is to be configured, in the HOST text box.

• Enter the port at which the specified HOST listens to in the PORT text box. The default port number is 80.

• In the URL box, the URL to be accessed by this test for extracting the Apache web server's performance statistics, will be displayed by default. The URL is: http://{Apache web server host}:{Apache web server port}/server-status.

• To make diagnosis more efficient and accurate, the eG Enterprise suite 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.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

• Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
