ocf_heartbeat_NodeUtilization - Node Utilization

ClusterLabscontributors(seetheresourceagentsourceforinformationaboutindividualauthors) resource-agents 4.16.0-3ubuntu 06/25/2025 OCF_HEARTBEAT_NODEUT(7)

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.

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"

ocf_heartbeat_NodeUtilization - Node Utilization

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.

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)
