Windows Event Log service

When this service has a scan interval of less than 5 minutes, the agent may take longer than the scan interval to gather the metrics. As a result, you may notice some scan intervals are not populated.

The Windows Event Log service enables you to monitor the Event logs on Windows devices.

Since you can assign multiple instances of the Windows Event Log service to a device, you can give each instance Service Identifier. The Service Identifier will be included in email notifications and on service-related displays, including the Active Issues view and the Status tab when editing a device, this enables you to maintain multiple instances of the Windows Event Log service in an organized fashion.

This service cannot use Self Healing.

For some sources, the agent may not be able to retrieve an event description due to:

the relevant Windows registry keys do not exist,
the relevant Windows registry keys do not contain valid data, or
the Event Message files are corrupted or were not found.

For any of these scenarios, the following message appears: "The description for Event ID ( Event ID Number ) in Source ( Source Name ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer."

The Windows Event Viewer can manage the following types of logs on a computer:

Security,
Application,
System Log,
Directory Service Log - only available on devices classed as Server-Windows,
File Replication Service Log - only available on devices classed as Server-Windows, and
DNS Server Log - only available on devices classed as Server-Windows.

Log Monitoring Options

To help in processing Windows logs, you can configure how the Windows agent reads the data from the log. Click Administration > Defaults > Agent and Probe settings and click the Agent tab. Configure the following options:

Multiline entries - evaluate each line separately

Some events in the Windows Event log include a line break, \n, in their description or source. When this option is enabled the Windows agent evaluates each line separately. If this option is disabled, all lines are treated as a single text string.

Perform Case Insensitive Text Searches

If this option is enabled, the regex provided in the Event Source field is treated as case insensitive. If this option is disabled, the regex provided in the event source is treated as case sensitive.

The initial scan of the Windows Event Log service will scan the most recent 100 entries in the Event log.

Thresholds

The thresholds for the Windows Event Log service are used for monitoring as:

Event Log Module Status	This is the status that is sent if you have selected Generate A Notification When An Event is Detected check box on the Service Details tab. The threshold for this module is 0 for normal and 1 for failed and all of the specified criteria under the Service Details tab have been met.
# of Duplicate Events	Indicates the number of identical identifiers that can be recorded in the log within the configured scan interval before triggering the transition to a different state. The default for this threshold is 0 for normal and 1 for failed.
