WEM Server Event Logs Test

How often should the test be executed.

The IP address of the host for which this test is to be configured.

Refers to the port used by the EventLog Service.  Here it is null.

Refers to the type of event logs to be monitored. The default value is Norskale Broker Service.

Using this page, administrators can configure the event sources, event IDs, and event descriptions to be monitored by this test. In order to enable administrators to easily and accurately provide this specification, this page provides the following options:

• Manually specify the event sources, IDs, and descriptions in the FILTER text area, or,
• Select a specification from the predefined filter policies listed in the FILTER box

For explicit, manual specification of the filter conditions, select the No option against the PolicyFilter field. This is the default selection. To choose from the list of pre-configured filter policies, or to create a new filter policy and then associate the same with the test, select the Yes option against the PolicyFilter field.

If the PolicyFilter flag is set to No, then a Filter text area will appear, wherein you will have to specify the event sources, event IDs, and event descriptions to be monitored. This specification should be of the following format: {Displayname}:{event_sources_to_be_included}:{event_sources_to_be_excluded}:{event_IDs_to_be_included}:{event_IDs_to_be_excluded}:{event_descriptions_to_be_included}:{event_descriptions_to_be_excluded}. For example, assume that the Filter text area takes the value, OS_events:all:Browse,Print:all:none:all:none. Here:

• OS_events is the display name that will appear as a descriptor of the test in the monitor UI;
• All indicates that all the event sources need to be considered while monitoring. To monitor specific event sources, provide the source names as a comma-separated list. To ensure that none of the event sources are monitored, specify none.
• Next, to ensure that specific event sources are excluded from monitoring, provide a comma-separated list of source names. Accordingly, in our example, Browse and Print have been excluded from monitoring. Alternatively, you can use all to indicate that all the event sources have to be excluded from monitoring, or none to denote that none of the event sources need be excluded.
• In the same manner, you can provide a comma-separated list of event IDs that require monitoring. The All in our example represents that all the event IDs need to be considered while monitoring.
• Similarly, the none (following all in our example) is indicative of the fact that none of the event IDs need to be excluded from monitoring. On the other hand, if you want to instruct the eG Enterprise system to ignore a few event IDs during monitoring, then provide the IDs as a comma-separated list. Likewise, specifying all makes sure that all the event IDs are excluded from monitoring.
• The all which follows implies that all events, regardless of description, need to be included for monitoring. To exclude all events, use none. On the other hand, if you provide a comma-separated list of event descriptions, then the events with the specified descriptions will alone be monitored. Event descriptions can be of any of the following forms - desc*, or desc, or desc,or desc*, or desc1*desc2, etc. desc here refers to any string that forms part of the description. A leading ‘*’ signifies any number of leading characters, while a trailing ‘*’ signifies any number of trailing characters.
• In the same way, you can also provide a comma-separated list of event descriptions to be excluded from monitoring. Here again, the specification can be of any of the following forms: desc*, or desc, or desc,or desc*, or desc1*desc2, etc. desc here refers to any string that forms part of the description. A leading ‘*’ signifies any number of leading characters, while a trailing ‘*’ signifies any number of trailing characters. In our example however, none is specified, indicating that no event descriptions are to be excluded from monitoring. If you use all instead, it would mean that all event descriptions are to be excluded from monitoring.

By default, the Filter parameter contains the value: all:all:none:all:none:all:none. Multiple filters are to be separated by semi-colons  (;).

Note:

The event sources and event IDs specified here should be exactly the same as that which appears in the Event Viewer window.  

On the other hand, if the PolicyFilter flag is set to Yes, then a Filter list box will appear, displaying the filter policies that pre-exist in the eG Enterprise system. A filter policy typically comprises of a specific set of event sources, event IDs, and event descriptions to be monitored. This specification is built into the policy in the following format:

{Policyname}:{event_sources_to_be_included}:{event_sources_to_be_excluded}:{event_IDs_to_be_included}:{event_IDs_to_be_excluded}:{event_descriptions_to_be_included}:{event_descriptions_to_be_excluded}

To monitor a specific combination of event sources, event IDs, and event descriptions, you can choose the corresponding filter policy from the Filter list box. Multiple filter policies can be so selected. Alternatively, you can modify any of the existing policies to suit your needs, or create a new filter policy. To facilitate this, a Click here link appears just above the test configuration section, once the Yes option is chosen against PolicyFilter. Clicking on the Click here link leads you to a page where you can modify the existing policies or create a new one. The changed policy or the new policy can then be associated with the test by selecting the policy name from the Filter list box in this page.

Typically, the eG manager generates email alerts only when the state of a specific measurement changes. A state change typically occurs only when the threshold of a measure is violated a configured number of times within a specified time window. While this ensured that the eG manager raised alarms only when the problem was severe enough, in some cases, it may cause one/more problems to go unnoticed, just because they did not result in a state change. For example, take the case of the EventLog test. When this test captures an error event for the very first time, the eG manager will send out a CRITICAL email alert with the details of the error event to configured recipients. Now, the next time the test runs, if a different error event is captured, the eG manager will keep the state of the measure as CRITICAL, but will not send out the details of this error event to the user; thus, the second issue will remain hidden from the user. To make sure that administrators do not miss/overlook critical issues, the eG Enterprise monitoring solution provides the stateless alerting capability. To enable this capability for this test, set the stateless alerts flag to Yes. This will ensure that email alerts are generated for this test, regardless of whether or not the state of the measures reported by this test changes.

By default, the Events During Restart flag is set to Yes. This ensures that whenever the agent is stopped and later started, the events that might have occurred during the period of non-availability of the agent are included in the number of events reported by the agent. Setting the flag to No ensures that the agent, when restarted, ignores the events that occurred during the time it was not available.

eG Enterprise also provides you with options to restrict the amount of storage required for event log tests. Towards this end, the DDforInformation and DDforWarning flags have been made available in this page. By default, both these flags are set to Yes, indicating that by default, the test generates detailed diagnostic measures for information events and warning events. If you do not want the test to generate and store detailed measures for information events, set the DDforInformation flag to No.

To ensure that the test does not generate and store detailed measures for warning events, set the DDforWarning flag to No.

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.
