NAME

       ocf_heartbeat_NodeUtilization - Node Utilization

SYNOPSIS

       NodeUtilization [start | stop | monitor | meta-data | validate-all]

DESCRIPTION

       The Node Utilization agent detects system parameters like available CPU, host memory and
       hypervisor memory availability, and adds them into the CIB for each node using
       crm_attribute. Run the agent as a clone resource to have it populate these parameters on
       each node. Note: Setting hv_memory only works with Xen at the moment, using the xl or xm
       command line tools.

SUPPORTED PARAMETERS

       dynamic
           If set, parameters will be updated if there are differences between the HA parameters
           and the system values when running the monitor action. If not set, the parameters will
           be set once when the resource instance starts.

           (optional, boolean, default true)

       utilization_cpu
           Enable setting node CPU utilization limit.

           (optional, boolean, default true)

       utilization_cpu_reservation
           Subtract this value when setting the CPU utilization parameter.

           (optional, integer, default 1)

       utilization_host_memory
           Enable setting available host memory.

           (optional, boolean, default true)

       utilization_host_memory_reservation
           Subtract this value when setting host memory utilization, in MB.

           (optional, integer, default 512)

       utilization_hv_memory
           Enable setting available hypervisor memory.

           (optional, boolean, default true)

       utilization_hv_memory_reservation
           Subtract this value when setting hypervisor memory utilization, in MB.

           (optional, integer, default 512)

SUPPORTED ACTIONS

       This resource agent supports the following actions (operations):

       start
           Starts the resource. Suggested minimum timeout: 90s.

       stop
           Stops the resource. Suggested minimum timeout: 100s.

       monitor
           Performs a detailed status check. Suggested minimum timeout: 20s. Suggested interval:
           60s.

       meta-data
           Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5s.

       validate-all
           Performs a validation of the resource configuration. Suggested minimum timeout: 30s.

EXAMPLE CRM SHELL

       The following is an example configuration for a NodeUtilization resource using the crm(8)
       shell:

           primitive p_NodeUtilization ocf:heartbeat:NodeUtilization \
             op monitor timeout="20s" interval="60s"

EXAMPLE PCS

       The following is an example configuration for a NodeUtilization resource using pcs(8)

           pcs resource create p_NodeUtilization ocf:heartbeat:NodeUtilization \
             op monitor timeout="20s" interval="60s"
