#blessed-ceph-dash ceph dashboard using blessed-contrib
The ceph-dash has a few different modes for accessing Ceph cluster information.
npm install blessed-ceph-dashDisplay statistics for the Ceph storage platform.
Usage: ceph-dash [options]
Options:
-l, --local Local Mode: Gather statistics if running locally to Ceph.
Expects 'ceph' in path and authenticated. [DEFAULT]
-r, --remote SSH Mode: Gather statistics from specified Ceph admin machine
via SSH. e.g --remote=servername.com
-n, --noauto NoAuto Mode: Do not gather statistics automatically. Used for
when you will manually POST data to ceph-dash
-u, --user User for SSH authentication to Ceph admin machine
[default: "root"]
--password Password for SSH authentication to Ceph admin machine (NOT
RECOMMENDED)
-k, --key SSH key file. (Default: ~/.ssh/id_rsa and ~/.ssh/id_dsa)
-p, --port Port to connect with SSH. [default: 22]
-b, --bind Port to listen on for 'ceph health -fjson' to be POSTd to.
[default: 3004]
-h, --help Show usage message.From a local machine to the Ceph cluster that already has admin rights, and can run ceph status without additional options (default auth).
ceph-dashFrom a machine that can connect to a 'Local' Ceph box over SSH. The 'Local' box we are SSHing to needs to be able to run the ceph status command without additional options (default auth)
ceph-dash --remote=someserver.com --port 22 --key .ssh/id_rsaYou could also specify --password=PASSWORD but obviously this is probably not a good idea as your password will now leak out.
From a machine that you want to run the dashboard you will launch ceph-dash and it will listen on a public port.
ceph-dash --noauto --bind 1234Then from inside your Ceph network you will POST the output of ceph status -f json to the machine that is running the dashboard. This method may be required for more advanced configurations and internal Ceph clusters that are inaccessible to any public methods.
