GM clock is not locked after threshold is changed in ptpconfig

ptp-operator.v4.14.0-202308291102

100%

1. Deploy SNO with PTP GM configuration

2. Check ptp metrics:
oc -n openshift-ptp exec $(oc get pods -n openshift-ptp|awk '/linuxptp-daemon.*Running/ {print $1}') -c linuxptp-daemon-container -- curl -s 127.0.0.1:9091/metrics
[...]
# TYPE openshift_ptp_clock_state gauge
openshift_ptp_clock_state{iface="CLOCK_REALTIME",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="phc2sys"} 1
openshift_ptp_clock_state{iface="ens3f0",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="GM"} 1
openshift_ptp_clock_state{iface="ens3f0",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="gnss"} 1
openshift_ptp_clock_state{iface="ens3fx",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="ts2phc"} 1
openshift_ptp_clock_state{iface="ens5fx",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="ptp4l"} 1
openshift_ptp_clock_state{iface="ens7fx",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="ptp4l"} 1

3. Run regression tests

4. Check ptp metrics again after ptp events and metrics tests are finished:

[kni@registry.ran-vcl01 ~]$ oc -n openshift-ptp exec $(oc get pods -n openshift-ptp|awk '/linuxptp-daemon.*Running/ {print $1}') -c linuxptp-daemon-container -- curl -s 127.0.0.1:9091/metrics # HELP cne_api_events_published Metric to get number of events published by the rest api [...] # HELP openshift_ptp_clock_class  # TYPE openshift_ptp_clock_class gauge openshift_ptp_clock_class{node="cnfde4.ptp.lab.eng.bos.redhat.com",process="ptp4l"} 248 # HELP openshift_ptp_clock_state 0 = FREERUN, 1 = LOCKED, 2 = HOLDOVER # TYPE openshift_ptp_clock_state gauge openshift_ptp_clock_state{iface="CLOCK_REALTIME",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="phc2sys"} 0 openshift_ptp_clock_state{iface="ens3f0",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="GM"} 1 openshift_ptp_clock_state{iface="ens3f0",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="gnss"} 1 openshift_ptp_clock_state{iface="ens3fx",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="ts2phc"} 0 openshift_ptp_clock_state{iface="ens5fx",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="ptp4l"} 0 openshift_ptp_clock_state{iface="ens7fx",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="ptp4l"} 0

Following deployment of SNO, ptp clocks were locked:

oc -n openshift-ptp exec $(oc get pods -n openshift-ptp|awk '/linuxptp-daemon.*Running/ {print $1}') -c linuxptp-daemon-container -- curl -s 127.0.0.1:9091/metrics
[...]

Following ptp events and metrics tests:

[kni@registry.ran-vcl01 ~]$ oc -n openshift-ptp exec $(oc get pods -n openshift-ptp|awk '/linuxptp-daemon.*Running/ {print $1}') -c linuxptp-daemon-container -- curl -s 127.0.0.1:9091/metrics # HELP cne_api_events_published Metric to get number of events published by the rest api [...] # HELP openshift_ptp_clock_class  # TYPE openshift_ptp_clock_class gauge openshift_ptp_clock_class{node="cnfde4.ptp.lab.eng.bos.redhat.com",process="ptp4l"} 248 # HELP openshift_ptp_clock_state 0 = FREERUN, 1 = LOCKED, 2 = HOLDOVER # TYPE openshift_ptp_clock_state gauge openshift_ptp_clock_state{iface="CLOCK_REALTIME",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="phc2sys"} 0 openshift_ptp_clock_state{iface="ens3f0",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="GM"} 1 openshift_ptp_clock_state{iface="ens3f0",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="gnss"} 1 openshift_ptp_clock_state{iface="ens3fx",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="ts2phc"} 0 openshift_ptp_clock_state{iface="ens5fx",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="ptp4l"} 0 openshift_ptp_clock_state{iface="ens7fx",node="cnfde4.ptp.lab.eng.bos.redhat.com",process="ptp4l"} 0

ptp clock is in sync.
