Added the `DS_PROMETHEUS` parameter in all the Grafana dashboard
definitions. When importing a definition into a Grafana Cloud instance
for example, the import form will allow selecting the datasource from
the currently available. OTOH when using an in-cluster instance such
as one installed through the Grafana helm chart, the parameter gets
overridden with the `values.yaml` entry
`dashboards.default.{name}.datasource`.
Also, the javascript snippet used in the dashboard definitions for
checking for the latest linkerd version has been wrapped around a hidden
div. This avoids showing the script itself when it gets escaped when
importing the definition into Grafana Cloud.

Using Grafana with Linkerd
You can install Grafana in various ways, like using the Grafana official Helm chart, or the Grafana Operator. Hosted solutions are also available, like Grafana Cloud.
The file grafana/values.yaml provides a default Helm config for the Grafana
official Helm
chart, which
pulls the Linkerd dashboards published at
https://grafana.com/orgs/linkerd/dashboards.
You can install the chart like this:
helm repo add grafana https://grafana.github.io/helm-charts
helm install grafana -n grafana --create-namespace grafana/grafana \
-f https://raw.githubusercontent.com/linkerd/linkerd2/main/grafana/values.yaml
Please make sure to update the entries in grafana/values.yaml before using the
file; in particular:
- auth and log settings under
grafana.ini datasources.datasources.yaml.datasources[0].urlshould point to your Prometheus service
The other installation methods can easily import those same dashboards using
their IDs, as listed in grafana/values.yaml.
In order to have the Linkerd Viz Dashboard show the Grafana icon there where
relevant, and have it link to the appropriate Grafana dashboard, make sure you
have a proper location set up in the grafana.url setting in Linkerd Viz's
values.yaml.
Note to developers
The grafana/dashboards directory contains the same dashboard definitions
published under https://grafana.com/orgs/linkerd. Please keep them in sync when
making any changes. After logging into grafana.com (using the linkerd account),
the dashboards can be managed under Org Settings -> My Dashboards.
