N. Using JP1/Base linked with the auto-scaling functionality

This section explains how to use JP1/Base linked with the auto-scaling functionality of a cloud platform (Amazon EC2).

The auto-scaling functionality provided by the Amazon EC2 service automatically increases the number of virtual machines (scales out) and deletes virtual machines (scales in) as needed, based on certain criteria such as thresholds for system load.

When JP1/Base is linked with the auto-scaling functionality, virtual machines that are added during scale out are automatically added to the system's monitoring targets. Specifically, settings for the following monitoring operations are automatically configured by the manager.

• Basic integrated monitoring by JP1/IM is set up, including:

  • Management of the system's hierarchical configuration based on the configuration definition (the IM configuration management functionality is not used)

  • Central management of various events that occur in the system by using JP1 events

  • Monitoring of remote hosts by using the health check function of JP1/Base

• Alarm monitoring by JP1/PFM is set up (if JP1/PFM is used for monitoring)

Note that, when a virtual machine is deleted during scale in, these settings are also cleared.
