Default Parameters for CassLngRnQryTest

This test tracks the currently executing queries on a Cassandra database node and determines the number of queries that have been running for a long time. Using this test, resource-intensive queries to a database can be quickly isolated.

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

• 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 ELAPSED TIME duration (in seconds) for which a query should have executed for it to be regarded as a long running query. The default value is 10.

• 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.
