Default Parameters for 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.

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

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

  • 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.

  • 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.
