OCF_HEARTBEAT_NODEUT(7) OCF resource agents OCF_HEARTBEAT_NODEUT(7)

ocf_heartbeat_NodeUtilization - Node Utilization

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

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.

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)

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.

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" 

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"
