NAMEocf_heartbeat_NodeUtilization - Node UtilizationSYNOPSISNodeUtilization [start | stop | monitor | meta-data |
validate-all]
DESCRIPTIONThe 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 PARAMETERSdynamicIf 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 ACTIONSThis resource agent supports the following actions (operations): startStarts 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 SHELLThe 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 PCSThe 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" SEE ALSOhttp://clusterlabs.org/AUTHORClusterLabs contributors (see the resource agent source for information about individual authors)
