Start with the rapl collector named in the repeated node_exporter errors and the failure reported at collector.go:161. Reproduce the read of /sys/class/powercap/intel-rapl:0/energy_uj on the reported Linux environment, then determine the expected behavior for this invalid-argument case. Done means the collector handles the reported condition without repeated collector-failed errors, with relevant coverage if the repository provides it.
