Configurable parameters for the test
Parameter Description

How often should the test be executed.

Host

The host for which the test is to be configured.

Port

The port number at which the specified host listens. By default, this is NULL.

Exclude Patterns

Here, specify a comma-separated list of error or warning message patterns to exclude from monitoring. Your pattern specification can be of any of the following formats: *error or warning messages*. This parameter is set to none by default, which indicates that no message will be excluded from monitoring.

Include Patterns

Here, specify a comma-separated list of error or warning message patterns to be monitored. The format of your specification should be: patternName:Pattern, where patternName refers to the unique name that you assign to every pattern configuration, which will appear as the descriptor of this test, and Pattern refers to any message pattern of the form*error or warning messages*. Multiple pattern specifications can be provided as: patternName1:Pattern1,patternName2:pattern2. This parameter is set to all:all by default, which indicates that all error/warning messages will be monitored by default.

SyslogFile

Specify the full path to the syslog file to be monitored.

RotatingFile

By default, the RotatingFile parameter is set to False. To instruct the eG Enterprise system to monitor newer log files also, set this parameter to True. Otherwise, set it to False.

Detailed Diagnosis

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.
