[ceph-users] get error when use prometheus plugin of ceph-mgr

[shawn tim]

Hello,
I just want to try prometheus plugin of ceph-mgr.
Following this doc(http://docs.ceph.com/docs/master/mgr/prometheus/)
<http://docs.ceph.com/docs/master/mgr/prometheus/)，I>. I get output like

[root@ceph01 ~]# curl localhost:9283/metrics/ | head

# HELP mds_mem_dir+ Directories opened

mds_mem_dir+{daemon="mds.ceph01"} 12.0
...

It seems everythins was  OK. But when prometheus connect it, I got errors:

WARN[0002] append failed                                 err="no token

job="ceph"}"
^CWARN[0014] Received SIGTERM, exiting gracefully...
source="main.go:340"

My prometheus config yml is

  - job_name: 'ceph mgr'
    scrape_interval: 5s
    # metrics_path: /metrics/
    # uncomment this still get error (Get http://10.10.0.125:9283/metrics:
net/http: invalid header field value "Bearer ..." for key Authorization )
    # bearer_token_file: /etc/ceph/ceph.mgr.ceph01.keyring
    # bearer_token: AQD6359ZCMK3DxAAyJYErZayMX/CRZyiyk/UGg==

    static_configs:
     - targets: ['10.10.0.125:9283']
       labels:
         group: 'production'


My ceph version is

[root@ceph01 ~]# ceph --version
ceph version 12.1.4 (a5f84b37668fc8e03165aaf5cbb380c78e4deba4) luminous (rc)

My prometheus version is

[root@prom01 prometheus-2.0.0-beta.2.linux-amd64]# ./prometheus --version
prometheus, version 2.0.0-beta.2 (branch: HEAD, revision:
a52f082939a566d5269671e98be06fc6bdf61d09)
  build user:       root@41a0740ea598
  build date:       20170818-08:16:50
  go version:       go1.8.3

Is there any steps I missed

Thanks for help !
