Agents Administration - Tests

Default Parameters for MySQLIndexIOTest This test auto-discovers the top indexes that are I/O intensive and for each index, reports the wait time and the read/write latency. Using this test, administrators can figure out the index that is experiencing slowness due to high read and write latencies. This page depicts the default parameters that need to be configured for the MySQLIndexIOTest. The TEST PERIOD list box helps the user to decide how often this test needs to be executed. In the DB text box, specify the name of a database on the MySQL server. The eG agent has to be configured with the credentials of a user who has server-wide Process and Select privileges on the monitored MySQL server. To know how to create such a user, refer to Configuring the eG Agent with Access Privileges topic in the Monitoring MySQL Database servers document. Specify the credentials of such a user in the USERNAME and PASSWORD textboxes. Confirm the password by retyping it in the CONFIRM PASSWORD textbox. By default, the ALLOW PUBLIC KEY flag is set to No. But, if the specified USER is created with caching_sha2_password as the authentication plugin, then the eG agent can connect to the target database server using RSA public key. To this effect, you have to set ALLOW PUBLIC KEY flag to Yes. By default, the SSL flag is set to No, indicating that the target MySQL database server is not SSL-enabled by default. To enable the test to connect to an SSL-enabled MySQL database server, set the SSL flag to Yes. If the eG agent is required to establish an encrypted connection with the target MySQL database server by authenticating the server's identity through verifying the server CA certificate, set VERIFY CA flag to Yes. By default, this flag is set to No. This parameter is applicable only if the VERIFY CA parameter is set to Yes. To verify the target server certificate, provide the password of the truststore file which contains the server CA certificate in the TRUSTSTORE PASSWORD text box. By default, this parameter is set to none. Confirm the PASSWORD by retyping it in the CONFIRM PASSWORD text box. This parameter is applicable only if the VERIFY CA parameter is set to Yes. To establish a connection with the target MySQL database server, the eG agent needs to have access to the client certificate. For this provide the password of the keystore file which contains the client certificate in the KEYSTORE PASSWORD text box. By default, this parameter is set to none. Confirm the PASSWORD by retyping it in the CONFIRM PASSWORD text box. By default, the detailed diagnosis of this test, if enabled, will report only the top-10 tables. This is why, the DD ROW COUNT parameter is set to 10 by default. If you want to include more or less tables in detailed diagnosis, then change the value of this parameter accordingly. 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.
