Default Parameters for EgClusterInfoTest

This test periodically checks whether the eG manager is operating in a cluster, and if so, reports what type of cluster it is. In addition, the test also reveals whether the eG manager being monitored is the primary or secondary manager in the cluster. Regardless of manager type, the test reports the number of agents that are explicitly assigned to the manager and the number of agents that are actually reporting to the manager; this way, the test points administrators to those agents that are mapped to the manager but are not actively reporting metrics and helps them initiate investigations in this regard. The test also enables administrators to track the usage of the data folder and figure out if the maximum amount of data that can be stored in that folder needs to be increased to avoid data loss during fail-over.

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

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

• In the JMX REMOTE PORT text box, specify the port at which the JMX listens for requests from remote hosts. In the <EG_MANAGER_INSTALL_DIR>\manager directory (on Windows; on Unix, this will be the /opt/egurkha/manager directory) of the eG manager, you will find a management.properties file. Set the port defined against the com.sun.management.jmxremote.port parameter of the file as the JMX REMOTE PORT.

• By default, JMX requires no authentication or security. Therefore, the USER, PASSWORD, and CONFIRM PASSWORD parameters are set to none by default.

• The JNDINAME is a lookup name for connecting to the JMX connector. By default, this is jmxrmi. If you have registered the JMX connector in the RMI registry using a different lookup name, then you can change this default value to reflect the same.

• The DD FREQUENCY refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD FREQUENCY.

• 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.
