Configuration of MsSqlMirorStatTest

For each database on a SQL server instance on which database mirroring is enabled, this test reports the current status of the mirroring session of that database, reveals what role that database plays in the mirroring session, and the current state of the witness. This way, administrators are promptly alerted when any mirroring session or witness switches to an abnormal state.

The default parameters associated with this test are:

  • The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

  • Specify the IP address of the target Microsoft SQL server in the HOST text box.

  • Specify the port number through which the target Microsoft SQL server communicates, in the PORT text box. The default port is 1433.

  • 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.

  • In the INSTANCE 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 an Microsoft SQL instance named “CFS”, enter this as the value of the INSTANCE parameter.

  • If an Microsoft SQL server 7.0/2000 is monitored, then provide the name of a SQL user with the Sysadmin role in the USER text box. While monitoring an Microsoft SQL server 2005/2008 on the other hand provide the name of a SQL user with the CONNECT SQL, VIEW ANY DATABASE, and VIEW SERVER STATE roles.

  • Provide the password on the specified USER in the PASSWORD text box.

  • Confirm the password by retyping it in the CONFIRM PASSWORD text box.

  • 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 chosen against the ISPASSIVE parameter 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.

  • If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

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

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
