Event Log Cleared Status Test

Administrators rely on event logs to capture and troubleshoot errors and warning events that occur on an Active Directory server. This is why, if a user inadvertently or wilfully clears an event log, many critical problem conditions may go unnoticed! Under such circumstances, it is only natural that administrators want to find out who cleared the logs, so that that user can be pulled up for questioning. The Event Log Cleared Status test helps with this. This test promptly alerts administrators if an application, system, or event log gets cleared. The detailed diagnosis of the test also points administrators to the user who cleared the log, thus assisting investigation.

Target of the test : An Active Directory

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every Active Directory site that is being monitored

Configurable parameters for the test
Parameters Description

Test period

This indicates how often should the test be executed.

Host

The IP address of the machine where the Active Directory is installed.

Port

The port number through which the Active Directory communicates. The default port number is 389.

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 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.
