SQL Query Wait Activity Test

This test monitors the wait types on the Microsoft SQL server, and reports the number and duration of waits of each type.

This test has been disabled by default for this layer. To enable this test, go to the enable / disable tests page using the menu sequence : Agents -> Tests -> Enable/Disable, pick Microsoft SQL as the Component type, Performance as the Test type, choose this 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.

Note:

This test is applicable only to Microsoft SQL Server 2005 (and above).

Target of the test : A Microsoft SQL server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for each wait type on the Microsoft SQL server instance being monitored

Configurable parameters for the test
TEST PERIOD - How often should the test be executed Host – The IP address of the Microsoft SQL server. Port - The port number through which the Microsoft SQL server communicates. The default port is 1433. ssl – If the Microsoft SQL server being monitored is an SSL-enabled server, then set the ssl flag to Yes. If not, then set the ssl flag to No. instance - In this text box, enter the name of a specific Microsoft SQL instance that is to be monitored. The default value of this parameter is “default”. To monitor a Microsoft SQL instance named “CFS”, enter this as the value of the INSTANCE parameter. USER – If a Microsoft SQL Server 7.0/2000 is monitored, then provide the name of a SQL user with the Sysadmin role in this text box. While monitoring a Microsoft SQL Server 2005 or above, provide the name of a SQL user with all of the privileges outlined in User Privileges Required for Monitoring Microsoft SQL server. password - The password of the specified user confirm password - Confirm the password by retyping it. domain - By default, none is displayed in the DOMAIN text box. If the ‘SQL server and Windows’ authentication has been enabled for the server being monitored, then the DOMAIN can continue to be none. On the other hand, if ‘Windows only’ authentication has been enabled, then, in the DOMAIN text box, specify the Windows domain in which the managed Microsoft SQL server exists. Also, in such a case, the USER name and PASSWORD that you provide should be that of a user authorized to access the monitored SQL server. exclude info - By default, this is set to none, indicating that the test will monitor all the wait types active on the Microsoft SQL server by default. To exclude specific wait types from the monitoring scope of this test, provide a comma-separated list of wait types in the EXCLUDE INFO text box. isntlmv2 - In some Windows networks, NTLM (NT LAN Manager) may be enabled. NTLM is a suite of Microsoft security protocols that provides authentication, integrity, and confidentiality to users. NTLM version 2 (“NTLMv2”) was concocted to address the security issues present in NTLM. By default, the isntlmv2 flag is set to No, indicating that NTLMv2 is not enabled by default on the target Microsoft SQL host. Set this flag to Yes if NTLMv2 is enabled on the target host. ISPASSIVE – If the value chosen is yes, then the Microsoft SQL server under consideration is a passive server in a SQL cluster. No alerts will be generated if the server is not running. Measures will be reported as “Not applicable" by the agent if the server is not up. dd frequency - Refers to the frequency with which detailed diagnosis measures are to be generated for this test. For instance, if you set to 1:1, it means that detailed measures will be generated every time this test runs, and also every time the test detects a problem. 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.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Number of waits:	Indicates the total number of waits for this wait type.	Number	The detailed diagnosis of this measure provides the query that caused the waits; you may want to fine-tune the queries to reduce the number of waits.
Avg wait time:	Indicates the average wait time for this wait type.	Seconds	Ideally, the value for this measure should be low. If the value for this measure is high, use the detailed diagnosis of the Num of waits measure to identify the queries that are causing the waits to remain for a long time. You may want to fine-tune the queries to reduce wait time.
Max wait time:	Indicates the maximum wait time for this wait type.	Seconds	Comparing the value of this measure across wait types will enable you to accurately isolate the wait type that is responsible for the longest waits.
