4.2.1 Enabling the health check function

The health check function is disabled by default. How to enable the health check function is described below. In a cluster system, enable the health check function on both the physical hosts and logical hosts after you complete the setup of the logical hosts.

To enable the health check function:

1. Register information to enable the health check function in the common definition information.

   1-1 Copy the model file (jbshc_setup.conf.model) for the common definition settings file (health check function) using any file name.

   1-2 Edit the copied file.

   1-3 Execute the following commands:

   jbssetcnf file-name-of-copied-file

   The health check function information is registered in the common definition information. The settings of the health check function are registered in the common definition information.

   For details on the jbssetcnf command, see jbssetcnf in 15. Commands.

   For details on the common definition settings file (health check function), see Common definition settings file (health check function) in 16. Definition Files.

2. Edit the health check definition file (jbshc.conf).

   Define the monitoring target host and monitoring interval. For details on the health check definition file, see Health check definition file in 16. Definition Files.

3. Change the settings for forwarding JP1 events.

   Add the following condition to the forwarding settings file (forward) to send JP1 events issued by the health check function to the higher-level management server.

   E.OBJECT_TYPE IN JBSHC

   For details on the forwarding settings file (forward), see Forwarding settings file in 16. Definition Files.

4. Restart all JP1/Base services and NNM (if using the SNMP trap converters).

   The health check function starts and process monitoring begins.

   If the health check action definition file contains an error, the line that contains the error is ignored. If that line contains a value that can be assumed to replace the ignored value, the function works by assuming that value.
