Specific Messages by Host Test

This test periodically checks the Syslog file for a specific rule set by administrator and reports the number of messages that match each rule. This way, administrator is alerted to the errors/warnings triggered at any level of the system, and enabled to initiate the remedial measures before anything untoward happens.

This test is disabled by default. To enable the test, go to the enable / disable tests page using the menu sequence : Agents -> Tests -> Enable/Disable, pick eG Syslog as the Component type, set Performance as the Test type, choose the test from the disabled tests list, and click on the >> button to move the test to the ENABLED TESTS list. Finally, click the Update button.

Target of the test : eG Syslog server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for each rule set by administrator.

Configurable parameters for the test
Parameter	Description
Test Period	How often should the test be executed
Host	The IP address of the host for which the test is being configured.
Port	The port at which the specified host listens. By default, this is NULL.
Rule Name	By default, the syslog file contains logs relating to multiple of host systems that are installed in your environment. In order to obtain the log information of your interest, you can define a set of rules according to which the messages should be read from the syslog file. To create a rule of your choice, click on the icon. The window that appears will provide you the below options for creating the rule. To know how to configure the rules refer to Configuring Rules for Monitoring.
Syslogfile	This test reports metrics by parsing the syslog file. Specify the full path to the syslog file here. For instance: C:\eGurkha\agent\syslog\syslog.
Rotatingfile	By default, this parameter is set to No. To instruct the eG Enterprise system to monitor newer log files also, set this parameter to Yes. Otherwise, set it to No.
DD frequency	Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD Frequency.
Detailed Diagnosis	To make diagnosis more efficient and accurate, the eG Enterprise 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.
