Configuration of TibSqlNetTest
Using the JDBC API, this test reports the availability and responsiveness of the server, and collects statistics pertaining to the traffic into and out of the database server.
The default parameters associated with this test are as follows:
In order to monitor a Tibero database server, a special database user account has to be created in every Tibero database instance that requires monitoring. A Click here hyperlink is available in the test configuration page, using which a new Tibero database user can be created. Alternatively, you can manually create the special database user. When doing so, ensure that this user is vested with the select any dictionary and create session privileges.
The sample script we recommend for user creation for eG monitoring is:
create user tibeg identified by tibeg default tablespace <users> temporary tablespace<temp>;
grant create session, select any dictionary tibeg;
The name of this user has to be specified in the USER text box, and the password of this user has to be entered in the PASSWORD text box. This login information is required to query Tibero's internal dynamic views, so as to fetch the current status / health of the various database components.
By default, the QUERY parameter is set to select * from v$instance. This implies that the eG agent monitors the responsiveness and availability of the database server based on the default query that has been hard-coded. However, sometimes, you may wish to monitor server's availability and responsiveness for a critical query of your choice. To achieve this, you can specify the critical query against this parameter by overriding the default value. Note that you can configure only a single SELECT query for this parameter.
Note:
To execute the SELECT query, the User should have the select privilege.
To make diagnosis more efficient and accurate, the eG system embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option against DETAILED DIAGNOSIS. To disable the capability, click on the Off option.
The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:
When changing the configuration for specific servers, a "*" beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a "$" or contain a series of "*". A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
