[ceph-users] node-exporter error problem

Hi, Our ceph cluster system health is fine but when I looked at the "ceph orch ps" one of the image has error state as stated below. node-exporter.ceph102 ceph102 error 7m ago 13m <unknown> prom/node-exporter <unknown> <unknown> How can we debug and locate the problem with ceph command? Another thing is where can I find that error log? Inside the docker or host? Regards.
