Key Management Events Test
The Key Management Service (KMS) activates computers on a local network, eliminating the need for individual computers to connect to Microsoft. To do this, KMS uses a client–server topology. KMS client computers can locate KMS host computers by using Domain Name System (DNS) or a static configuration. KMS clients contact the KMS host by using remote procedure call (RPC). A KMS host responds to each valid activation request from a KMS client with the count of how many computers have contacted the KMS host for activation. Clients that receive a count below their activation threshold are not activated. If a computer running for e.g, Windows Server 2012 or Windows Server 2012 R2 receives an activation count that is 25 or ≥25, it is activated.
If users to a Windows server are having trouble logging on, administrators may want to check the Key Management Service event log to see if it is owing to an issue with KMS. This event log tracks events related to Kerberos key distribution, when a server functions as a key distribution center. To enable administrators to rapidly capture error/warning events captured by this event log and troubleshoot logon issues that occur, administrators can run the Key Management Events test. This test monitors the Key Management Service event log and reports the count and details of errors and warning events captured by that log.
Target of the test : An Active Directory server
Agent deploying the test : An internal agent
Outputs of the test : One set of results for the server being monitored
Parameters | Description |
---|---|
Test period |
This indicates how often should the test be executed. |
Host |
The host for which the test is to be configured. |
Port |
Refers to the port used by the EventLog Service. Here it is null. |
Logtype |
Refers to the type of event logs to be monitored. By default, this is set to Key Management Service. |
Policy Based Filter |
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:
For explicit, manual specification of the filter conditions, select the No option against the Policy Based Filter 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 this field. |
Filter |
If the Policy Based Filter 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:
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 Policy Based Filter 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 the Policy Based Filter. 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. |
Events During Restart |
By default, this 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. |
Stateless Alerts |
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. |
UseWMI |
The eG agent can either use WMI to extract event log statistics or directly parse the event logs using event log APIs. If this flag is Yes, then WMI is used. If not, the event log APIs are used. This option is provided because on some Windows systems (especially ones with service pack 3 or lower), the use of WMI access to event logs can cause the CPU usage of the WinMgmt process to shoot up. On such systems, set this parameter value to No. |
DDforInformation |
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 this flag to No. |
DDforWarning |
To ensure that the test does not generate and store detailed measures for warning events, set this flag 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:
|
