Default Parameters for MsSqlExpPlStTest

This test periodically monitors the target Microsoft SQL server and reports the number of times that the explain plans were changed during query execution. The detailed diagnosis reported by this test reveals the details on plan changes for each query, name of all the plans used for each query, etc.

This page depicts the default parameters that need to be configured for the MsSqlExpPlStTest.

  • The TEST PERIOD list box helps the user to decide how often this test needs to be executed. By default, this is set to 60 minutes.

  • If a Microsoft SQL Server 7.0/2000 is monitored, then provide the name of a SQL user with the Sysadmin role in USER 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.

  • Specify the password corresponding to the mentioned user in the PASSWORD textbox.

  • Confirm the PASSWORD by retyping it in the CONFIRM PASSWORD textbox.

  • Enter the name of a specific Microsoft SQL instance that is to be monitored against INSTANCE parameter. 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.

  • 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.

  • 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.

  • If the value of ISPASSIVE 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.

  • By default, the SSL flag is set to No, indicating that the target Microsoft SQL server is not SSL-enabled by default. To enable the test to connect to an SSL-enabled Microsoft SQL server, set the SSL flag to Yes.

  • 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.

  • Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz*” and $port will be changed to “80” when configuring a test.
