ceph dashboard #0

Supports: focal groovy hirsute


Enable the ceph dashboard on the ceph mon units


The ceph-dashboard charm deploys the Ceph Dashboard, a built-in web-based Ceph management and monitoring application.



This section covers common and/or important configuration options. See file config.yaml for the full list of options, along with their descriptions and default values. See the Juju documentation for details on configuring applications.


Sets the URL of the Grafana API when using embedded graphs. See Embedded Grafana dashboards.


Sets the hostname or address of the public endpoint used to access the dashboard.


Sets whether certain password restrictions are enforced when a user is created or changes their password.


There are a number of password-* options which impose constraints on which passwords can be used. These options are ignored unless enable-password-policy is set to 'True'.


We are assuming a pre-existing Ceph cluster.

Deploy the ceph-dashboard as a subordinate to the ceph-mon charm.

juju deploy ceph-dashboard
juju add-relation ceph-dashboard:dashboard ceph-mon:dashboard

TLS is a requirement for this charm. Enable it by adding a relation to the vault application:

juju add-relation ceph-dashboard:certificates vault:certificates

See Managing TLS certificates in the OpenStack Charms Deployment Guide for more information on TLS.

Note: This charm also supports TLS configuration via charm options ssl_cert, ssl_key, and ssl_ca.

Embedded Grafana dashboards

To embed Grafana dashboards within the Ceph dashboard some additional relations are required (Grafana, Telegraf, and Prometheus are assumed to be pre-existing):

juju add-relation ceph-dashboard:grafana-dashboard grafana:dashboards
juju add-relation ceph-dashboard:prometheus prometheus:website
juju add-relation ceph-mon:prometheus prometheus:target
juju add-relation ceph-osd:juju-info telegraf:juju-info
juju add-relation ceph-mon:juju-info telegraf:juju-info

Grafana, Telegraf, and Prometheus should be related in the standard way:

juju add-relation grafana:grafana-source prometheus:grafana-source
juju add-relation telegraf:prometheus-client prometheus:target
juju add-relation telegraf:dashboards grafana:dashboards

When Grafana is integrated with the Ceph Dashboard it requires TLS, so add a relation to Vault (the grafana charm also supports TLS configuration via ssl_* charm options):

juju add-relation grafana:certificates vault:certificates

Important: Ceph Dashboard will (silently) fail to display Grafana output if the client browser cannot validate the Grafana server's TLS certificate. Either ensure the signing CA certificate is known to the browser or, if in a testing environment, contact the Grafana dashboard directly and have the browser accept the unverified certificate.

Grafana should be configured with the following charm options:

juju config grafana anonymous=True
juju config grafana allow_embedding=True

The grafana charm also requires the vonage-status-panel and grafana-piechart-panel plugins. The install_plugins configuration option should be set to include URLs from which these plugins can be downloaded. They are currently available from https://storage.googleapis.com/plugins-community. For example:

juju config grafana install_plugins="https://storage.googleapis.com/plugins-community/vonage-status-panel/release/1.0.11/vonage-status-panel-1.0.11.zip,https://storage.googleapis.com/plugins-community/grafana-piechart-panel/release/1.6.2/grafana-piechart-panel-1.6.2.zip"

Telegraf should be configured with the following charm option:

juju config telegraf hostname="{host}"

Note: The above command is to be invoked verbatim; no substitution is required.

Currently the dashboard does not autodetect the API endpoint of the Grafana service. It needs to be provided via a configuration option:

juju config ceph-dashboard grafana-api-url="https://<IP of grafana unit>:3000"

Prometheus alerting

To enable alerting for an existing Prometheus service add the following relations:

juju add-relation ceph-dashboard:prometheus prometheus:website
juju add-relation ceph-mon:prometheus prometheus:target
juju add-relation ceph-dashboard:alertmanager-service prometheus-alertmanager:alertmanager-service
juju add-relation prometheus:alertmanager-service prometheus-alertmanager:alertmanager-service

Ceph Object storage

To enable Object storage management of an existing Ceph RADOS Gateway service add the following relation:

juju relate ceph-dashboard:radosgw-dashboard ceph-radosgw:radosgw-user

Note: For Ceph versions older than Pacific the dashboard can only be related to a single ceph-radosgw application.


This section lists Juju actions supported by the charm. Actions allow specific operations to be performed on a per-unit basis. To display action descriptions run juju actions --schema ceph-dashboard. If the charm is not deployed then see file actions.yaml.

  • add-user
  • delete-user


The OpenStack Charms project maintains two documentation guides:


Please report bugs on Launchpad.


(boolean) Log requests made to the dashboard REST API to the Ceph audit log.
(boolean) Include payload in Ceph audit logs. audit-api-enabled must be set to True to enable this.,
(boolean) Control debug mode. It is recommended that debug be disabled in production deployments.
(boolean) Enable password policy
(string) URL of grafana api. The url must be using https.
(string) Message of the day settings. Should be in the format "severity|expires|message". Set to "" to disable.
(boolean) Check password meets a complexity score of password-policy-min-complexity. See https://docs.ceph.com/en/latest/mgr/dashboard/#password-policy
(boolean) Reject password if it contains a word from a forbidden list.
(boolean) Reject password if it is shorter then password-policy-min-length
(boolean) Reject password if it matches previous password.
(boolean) Reject password if password contains consecutive repeating charachters.
(boolean) Reject password if it contains a sequence of sequential characters. e.g. a password containing '123' or 'efg' would be rejected.
(boolean) Reject password if username is included in password.
(int) Set minimum password complexity score. See https://docs.ceph.com/en/latest/mgr/dashboard/#password-policy
(int) Set minimum password length.
(string) The hostname or address of the public endpoints created for the dashboard
(string) SSL CA to use with the certificate and key provided - this is only required if you are providing a privately signed ssl_cert and ssl_key.
(string) SSL certificate to install and use for API ports. Setting this value and ssl_key will enable reverse proxying, point Neutron's entry in the Keystone catalog to use https, and override any certificate and key issued by Keystone (if it is configured to do so).
(string) SSL key to use with certificate specified as ssl_cert.
