Grafana - Updated all graphs on dashboard from metric selection

Question

I have a prometheus node which collects job data from Jenkins and stores it eg:

jenkins_job_last_completed_build_queuing_duration_seconds{jobname="j1"} 0.01
jenkins_job_last_completed_build_timestamp_seconds{jobname="j1"} 1489006588.334

etc.

In grafana I want ot have a dashboard with a bunch of graphs for the different metrics and some way of choosing which job to display on the graphs.
eg I log onto the dashboard and select j1 somehow and all the graphs show the data for j1. Then I change my selection to j2 and all the graphs update to show j2 data.

I know I can do this on a per graph basis by clicking in the legend, but I want to do them all at once.

Is this possible?

Cheers

Yes! You can make a template query in grafana that is populated with a label value. Docs are here: http://docs.grafana.org/features/datasources/prometheus/#templated-queries

We do something similar to select a namespace in a dashboard to see the memory & CPU consumption of the services in that namespace. Our dashboard looks like this:

And the queries look like:

namespace_name:container_cpu_usage_seconds_total:sum_rate{namespace=\\"$namespace\\"}

I don't know how to make the variable with the UI, I generate the config with our grafanalib project ( https://github.com/weaveworks/grafanalib ) and it looks like this:

"templating": { "list": [ { "allValue": null, "current": { "tags": [], "text": "default", "value": "default" }, "datasource": "Scope-as-a-Service Prometheus", "hide": 0, "includeAll": false, "label": "Namespace", "multi": false, "name": "namespace", "options": [], "query": "label_values(k8s_pod_status_ready, namespace)", "refresh": 1, "regex": "", "sort": 1, "tagValuesQuery": null, "tagsQuery": null, "type": "query" } ] },
