Chapter 8. Config map reference for the Cluster Monitoring Operator 8.1. Cluster Monitoring Operator configuration reference Parts of OpenShift Container Platform cluster monitoring are configurable. The API is accessible by setting parameters defined in various config maps. To configure monitoring components, edit the ConfigMap object named cluster-monitoring-config in the openshift-monitoring namespace. These configurations are defined by ClusterMonitoringConfiguration . To configure monitoring components that monitor user-defined projects, edit the ConfigMap object named user-workload-monitoring-config in the openshift-user-workload-monitoring namespace. These configurations are defined by UserWorkloadConfiguration . The configuration file is always defined under the config.yaml key in the config map data. Important Not all configuration parameters for the monitoring stack are exposed. Only the parameters and fields listed in this reference are supported for configuration. For more information about supported configurations, see Maintenance and support for monitoring Configuring cluster monitoring is optional. If a configuration does not exist or is empty, default values are used. If the configuration is invalid YAML data, the Cluster Monitoring Operator stops reconciling the resources and reports Degraded=True in the status conditions of the Operator. 8.2.

NodeExporterCollectorSystemdConfig 8.19.1. Description Use the NodeExporterCollectorSystemdConfig resource to enable or disable the systemd collector of the node-exporter agent. By default, the systemd collector is disabled. If enabled, the following metrics become available: node_systemd_system_running , node_systemd_units , node_systemd_version . If the unit uses a socket, it also generates the following metrics: node_systemd_socket_accepted_connections_total , node_systemd_socket_current_connections , node_systemd_socket_refused_connections_total . You can use the units parameter to select the systemd units to be included by the systemd collector. The selected units are used to generate the node_systemd_unit_state metric, which shows the state of each systemd unit. However, this metric's cardinality might be high (at least five series per unit per node). If you enable this collector with a long list of selected units, closely monitor the prometheus-k8s deployment for excessive memory usage. Note that the node_systemd_timer_last_trigger_seconds metric is only shown if you have configured the value of the units parameter as logrotate.timer . Appears in: NodeExporterCollectorConfig Property Type Description enabled bool A Boolean flag that enables or disables the systemd collector. units []string A list of regular expression (regex) patterns that match systemd units to be included by the systemd collector.

Appears in: ClusterMonitoringConfiguration Property Type Description collectors NodeExporterCollectorConfig Defines which collectors are enabled and their additional configuration parameters. maxProcs uint32 The target number of CPUs on which the node-exporter's process will run. The default value is 0 , which means that node-exporter runs on all CPUs. If a kernel deadlock occurs or if performance degrades when reading from sysfs concurrently, you can change this value to 1 , which limits node-exporter to running on one CPU. For nodes with a high CPU count, you can set the limit to a low number, which saves resources by preventing Go routines from being scheduled to run on all CPUs. However, I/O performance degrades if the maxProcs value is set too low and there are many metrics to collect. ignoredNetworkDevices *[]string A list of network devices, defined as regular expressions, that you want to exclude from the relevant collector configuration such as netdev and netclass . If no list is specified, the Cluster Monitoring Operator uses a predefined list of devices to be excluded to minimize the impact on memory usage. If the list is empty, no devices are excluded.
