Entity Summary

The entity summary is the entity's main page, and contains all the information about a specific entity:

  • Dashboards should be listed in the definition.yml file, under the dashboardTemplates section.
  • If the entity type only has one source of data, use newRelic as the default source.
  • By default, each NRQL query will be filtered by the entity GUID. If you want to disable this behavior, set filterNRQLByEntityID to false. When you disable this behavior, you must manually specify the filter for all NRQL queries in the dashboard. See Filtering by Entity GUID for more details.
dashboardTemplates:
  newRelic:
    template: dashboard.json
    filterNRQLByEntityID: true

In order to get a dashboard in JSON format, create a dashboard in New Relic and export it as json.

Export Dashboard

Copy the JSON content to the dashboard.json file.

Make sure your dashboard is valid running our sanitizer:

docker-compose run sanitize-dashboards

You can also run it with npm:

cd validator && npm i && npm run sanitize-dashboards

Multiple sources of data

In some cases your entity will receive metrics from different sources. We provide a different summary page representation for each one of them.

In this example, the entity must have prometheus and newRelic in the instrumentation.provider tag. The first tag value that matches the entity will serve the summary page:

dashboardTemplates:
  newRelic:
    template: newRelic_dashboard.json
  prometheus:
    template: prometheus_dashboard.json

We recommend prefixing dashboard names with the source name.

You can also specify both provider and name in the form of {provider}/{name}.

  1. Add the provider as a value of the instrumentation.provider tag. For example, provider: kentik.
  2. Add the name of the provider in the instrumentation.name tag. For example, provider name: netflow-events.

Note that query semantics (such as average vs counts, units, etc.) should match in each implementation. If no rule matches, the first one on the list will be used. In the example above, prometheus would be used.

dashboardTemplates:
  kentik/netflow-events:
    template: kentik_netflow-evens_dashboard.json

Filtering by Entity GUID

dashboardTemplates:
  newRelic:
    template: dashboard.json
    filterNRQLByEntityID: true

By default the NRQL query will be filtered by the entity GUID. If you want to disable this behavior, set filterNRQLByEntityID to false. When you disable this behavior, you must manually specify the filter for all NRQL queries in the dashboard. You can use mustache syntax to reference available variables.

For example, if you want to filter by the entity GUID, you can use the following NRQL query:

FROM Metric SELECT latest(k8s.clusterName) as 'Cluster Name' WHERE metricName = 'k8s.pod.startTime' AND `entity.guid` = '{{entity.id}}'

Available variables

Variable Description
entity.id The entity GUID
tags.* Any tag value, see below for more details on how to find the tag name

Finding the tag name

Tags are assigned to all entities based on the tags defined in an entity's definition file. For example, the ext-pixie_postgres entity type defines k8s.cluster.name as a tag. https://github.com/newrelic/entity-definitions/blob/42b7a5a1780d897312f231aac3271898f8c87ff5/definitions/ext-pixie_postgres/definition.yml#L34-L35

In a NRQL query, you can reference the value of a tag using tags.k8s.cluster.name like so:

FROM Metric SELECT latest(k8s.clusterName) as 'Cluster Name' WHERE k8s.cluster.name = '{{tags.k8s.cluster.name}}'
