OCF_HEARTBEAT_NODEUT(7) OCF resource agents OCF_HEARTBEAT_NODEUT(7) 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. Sug- gested interval: 60s. meta-data Retrieves resource agent metadata (internal use only). Suggested mini- mum timeout: 5s. validate-all Performs a validation of the resource configuration. Suggested minimum timeout: 30s.
