7.19. NodeExporterConfig

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. If you modify this setting, monitor the prometheus-k8s deployment closely for excessive memory usage.

resources

*v1.ResourceRequirements

Defines resource requests and limits for the NodeExporter container.
