Description Pawan 2021-03-30 04:52:08 UTC

Description of problem:
Command to get per daemon service events is failing with error : Error EINVAL: invalid command

Ref doc : https://docs.ceph.com/en/latest/cephadm/troubleshooting/#per-service-and-per-daemon-events

Getting events per service is working as expected with the given command : 
# ceph orch ls --service_name=mon --format yaml
service_type: mon
service_name: mon
placement:
  label: mon
status:
  container_image_id: c1a8b8b28c915288d9ab4485a9611590ef247e587875464613d1da7fdaed356d
  container_image_name: mix
  created: '2021-03-27T03:44:24.493744Z'
  last_refresh: '2021-03-30T04:10:38.948346Z'

  size: 5

# ceph orch ls --service_name=mgr --format yaml
service_type: mgr
service_name: mgr
placement:
  label: mgr
status:
  container_image_id: c1a8b8b28c915288d9ab4485a9611590ef247e587875464613d1da7fdaed356d

  last_refresh: '2021-03-30T04:10:39.833181Z'
  running: 3
  size: 2


But command not working for per daemon is failing :

# ceph orch ceph --service-type mds --daemon-id=ceph-pdhiran-adm-1616815085515-node2-mon-mgr-mds-node-exporter.ppdhsz --format yaml
Invalid command: ceph not in start|stop|restart|redeploy|reconfig
orch start|stop|restart|redeploy|reconfig <service_name> :  Start, stop, restart, redeploy, or reconfig an entire service (i.e. all daemons)
Error EINVAL: invalid command

[ceph: root@ceph-pdhiran-adm-1616815085515-node1-mon-installer-node-exporte ceph]# ceph orch ceph --service-type mgr  --daemon-id=ceph-pdhiran-adm-1616815085515-node1-mon-installer-node-exporte.tlovmj --format yaml
Invalid command: ceph not in start|stop|restart|redeploy|reconfig
orch start|stop|restart|redeploy|reconfig <service_name> :  Start, stop, restart, redeploy, or reconfig an entire service (i.e. all daemons)
Error EINVAL: invalid command

with the help provided with the error message, tried the modified command, but it says No service reported.

#  ceph orch ls --service_type mgr --service_name ceph-pdhiran-adm-1616815085515-node1-mon-installer-node-exporte.tlovmj --format yaml
No services reported

Comment 1 Adam King 2021-04-08 20:02:52 UTC

The documentation for the single daemon events command is wrong. It should be something like "ceph orch ps --service-name <service-name> --daemon-id <daemon-id> --format yaml"


For example, I can use that setup to get the events for a daemon "mon.vm-02" I had on a cluster:


[ceph: root@vm-00 /]# ceph orch ps --service-name mon --daemon-id=vm-02 --format yaml
daemon_type: mon
daemon_id: vm-02
hostname: vm-02
container_id: 47c67e1b6064
container_image_id: 54d9b6d180154d293902d197ed6a1e6279a8f3865989cf687cb36f4c2b630a4a
