Managing HP Serviceguard A.11.20.10 for Linux, December 2012

• generic_resource_name
• generic_resource_evaluation_type
• generic_resource_up_criteria
See the descriptions that follow.
The following is an example of defining generic resource parameters:
generic_resource_name cpu_monitor
generic_resource_evaluation_type during_package_start
generic_resource_up_criteria <50
See the package configuration file for more examples.
6.1.4.33 generic_resource_evaluation_type
Defines when the status of a generic resource is evaluated.
Valid values are during_package_start and before_package_start. The default is
during_package_start.
The resources that will be available during the course of start of the package must be configured
with an evaluation_type as during_package_start.
Monitoring for these generic resources can be started and stopped as a part of the package, and
the monitoring script can be configured as a service. This can be achieved by configuring a
service_name and a service_cmd containing the full path name of the monitoring
executable/script. The monitoring of the generic resource starts only when the monitoring scripts
are started and not at the start of the package.
For information on monitoring scripts, see “Monitoring Script for Generic Resources” (page 289).
If there is a common generic resource that needs to be monitored as a part of multiple packages,
then the monitoring script for that resource can be launched as part of one package and all other
packages can use the same monitoring script. There is no need to launch multiple monitors for a
common resource. If the package that has started the monitoring script fails or is halted, then all
the other packages that are using this common resource also fail.
These resources will usually be of the evaluation_type before_package_start and it is
recommended to configure the monitoring script in a multi-node package.
These resources must be available (status must be 'up') in order to start the package and the
monitoring scripts for these resources must be configured outside of the application package.
6.1.4.34 generic_resource_up_criteria
Defines a criterion to determine whether the status of a generic resource identified by
generic_resource_name is up.
Attribute requires a logical operator and a value. The operators ==, !=, >, <, >=, and <= are
allowed. Values must be positive integer values ranging from 1 to 2147483647.
