Grafana Gnocchi datasource Travis CI

Gnocchi datasource for Grafana >= 4

Installation via

$ sudo grafana-cli plugins install gnocchixyz-gnocchi-datasource

Installation from sources

$ npm install
$ ./  # This also build the plugin under dist/

$ ln -s dist /var/lib/grafana/plugins/grafana-gnocchi-datasource $ # or $ cp -a dist /var/lib/grafana/plugins/grafana-gnocchi-datasource

Configuration Panel

NameThe data source name.
DefaultDefault data source means that it will be pre-selected for new panels.
UrlThe http protocol, ip and port of your Keystone or Gnocchi server (default port is usually 8080)
AccessProxy = access via Grafana backend, Direct = access directory from browser.
TokenA valid Keystone token
ProjectThe keystone user
UserThe Keystone user
PasswordThe Keystone password

Note: If the Keystone server is set as URL, the Gnocchi server will be autodiscovered. This works only if Access = Direct, and CORS is properly configured on Keystone and Gnocchi side.

Query editor

The editor leverage thes Dynamic Aggregate API of Gnocchi:

  • Select first the resource type you are looking for.
  • Create a query to select all resources you need.
  • Create an operation that selects metric and does math on/between them.
  • Set label to name each graph with text or with resource attributes.

The Query format is documented as STRING format in Resource search section of Gnocchi documentations. The Operation format is documented in Dynamic Aggregates section of Gnocchi documentations.

Other Query type exists for special use case and for old Gnocchi version that doesn't support Dynamic aggregates


Labels can be expressed with resources attributes and metric name. To do so attribute must be surrounded by ${} or prefixed by $.

For example, takes the metric regex "cpu_*", the label "$display_name-${host}.foo-$type $metric" and a query that returns these resources::

    "display_name": "myfirstvm",
    "host": "compute1",
    "id": "6868da77-fa82-4e67-aba9-270c5ae8cbca",
    "image_ref": "http://image",
    "type": "instance",
    "server_group": "autoscalig_group",
    "metrics": {"cpu_util": "1634173a-e3b8-4119-9eba-fa9a4d971c3b"}
    "display_name": "mysecondvm",
    "host": "compute3",
    "id": "f898ba55-bbea-460f-985c-3d1243348304",
    "image_ref": "http://image",
    "type": "instance",
    "server_group": "autoscalig_group",
    "metrics": {"cpu_util": "58b233f4-65ba-4aeb-97ba-b8bc0feec97e",
                "cpu_time": "6ff95458-97b4-4b08-af03-7d18b05d277e"}

The resulting labels are:: cpu_util cpu_util cpu_time

Templated queries

Gnocchi Datasource Plugin provides following functions in Variables values query field in Templating Editor.

metrics(resource_id)Returns a list of metrics available for the resource identified by ‘resource_id’
resources(resource_type, attribute, query)Returns a list of resource attribute matching query.
resources(resource_type, attribute1, attribute2, query)Returns a list of resource attribute matching query, attribute1 is diplayed in selector, attribute1 used for templating.

For details of Query format, please refer to the Gnocchi and Gnocchi client documentations.

Current Limitation

Grafana doesn’t allow to query two different servers when using the proxy mode, so we are not able to query Keystone for a token and then query Gnocchi (Except if Gnocchi and Keystone live into the same HTTP host).

In direct mode, CORS MUST be enabled on Keystone and Gnocchi servers.
