Similarly, consider another package pkg2 that requires the 'CPU' to be configured as before_package_start.

lan1

generic_resource_monitors generic_resource_monitors = up same_node

Thus, the monitoring scripts for all the generic resources of type before_package_start are configured in one single multi-node package and any package that requires this generic resource can just configure the generic resource name.

If a common resource has to be monitored in multiple packages, the monitoring scripts can be configured in the multi-node package described above and multiple packages can define the same generic resource name in their package configuration files as seen for the generic resource 'lan1' in the above example.

Figure 49 depicts a multi-node package containing two monitoring scripts configured — one to monitor a lan and other to monitor a CPU. The two packages are configured with the generic resource names and are dependent on the multi-node package.
