Configuration of CassSqlNetTest

This test monitors the availability and responsiveness of the Cassandra Database node by emulating a client connecting and executing queries on the Cassandra Database node.

The default parameters associated with this test are as follows:

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

  • Specify the IP address of the host for which the test is being configured.

  • Specify the PORT at which the HOST listens. The default value is 9042.

  • Specify the name of the CQL USER with the following privileges in this text box:

    SELECT privilege on the system_traces.sessions table

    SELECT privilege on the system.peer_events table

  • Specify the password corresponding to the CQL User in CQL PASSWORD text box.

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

  • Specify the name of the keyspace to connect to in KEYSPACE NAME text box. The default is “system_schema”. To monitor multiple keyspaces, ensure that the keyspaces are provided as a colon-separated list. Alternatively, you can use the semi-colon(;) as the separator for the keyspaces.

  • Specify the select query to execute in QUERY text box. The default is “select * from keyspaces”. If the target Cassandra Database node is installed as case sensitive, then the value of query parameter should also be case sensitive. If multiple keyspaces are specified in the DATABASE text box, then you will have to provide multiple queries here separated by a semi-colon (;) - for e.g., select * from keyspaces;select * from alarm. Every keyspace being monitored, should have a corresponding Query specification.

  • To make diagnosis more efficient and accurate, the eG Enterprise suite 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.

  • 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.
