Description of problem:
openshift_ptp_interface_role gauge is missing from metrics after restarting sidecar container. Automated test and manual test steps show same result.
Version-Release number of selected component (if applicable):
ptp-operator.v4.20.0-202507011152 Cluster version is 4.20.0-0.nightly-2025-07-01-051543
How reproducible:
100%
Steps to Reproduce:
1. Deploy 4.20 SNO with PTP
2. Examine metrics:
oc exec -it ds/linuxptp-daemon -n openshift-ptp -c linuxptp-daemon-container -- curl -s localhost:9091/metrics
Metrics should include a section for openshift_ptp_interface_role gauge:
# TYPE openshift_ptp_interface_role gauge
openshift_ptp_interface_role{iface="eno12399",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 1
openshift_ptp_interface_role{iface="ens3f1np1",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 1
openshift_ptp_interface_role{iface="ens5f0",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 2
openshift_ptp_interface_role{iface="ens5f1",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 2
openshift_ptp_interface_role{iface="ens5f2",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 2
openshift_ptp_interface_role{iface="ens5f3",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 2
openshift_ptp_interface_role{iface="ens7f3",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 2
3. Restart sidecar:
oc exec ds/linuxptp-daemon -c cloud-event-proxy -n openshift-ptp -- sh -c "kill -9 \$(ps aux | grep cloud-event-proxy | grep -v grep | awk '{print \$2}')"
4. Wait for recovery and check metrics for openshift_ptp_interface_role gauge: oc exec -it ds/linuxptp-daemon -n openshift-ptp -c linuxptp-daemon-container -- curl -s localhost:9091/metrics | grep -i role
Actual results:
No openshift_ptp_interface_role gauge is shown in metrics.
Expected results:
openshift_ptp_interface_role gauge shows role for all interfaces.
Additional info:
Retested on 4.18 with ptp-operator.v4.18.0-202507081733 with same results.
