Few ports on some devices have UNKNOWN status with 'Terminated by signal 9 (Killed)' message

Hi All,
I need help on the above issue. I have a config defined in global configuration for some Nexus N9k’s for 3 differenet sites. All three sites have satellite servers to poll the devices. For two sites all services on these devices are up but for one site some of the sevices have UNKNWON status with the below message:

<Terminated by signal 9 (Killed).>

For example I am monitoring porst from Eth1/1 to Eth1/10, ports Eth1/4 are UNKNOWN and rest are good.

Any advice fix this? I have restarted the services, rebooted the satellites, reconfigured the devices but no luck

Hi and welcome,

for helping it would be very helpful how you configured this service check and which check you are using!
