Grafana templates

[Harmen B]

Hello,

I'm trying to get 'templates' working with prom and grafana. These things: http://docs.grafana.org/reference/templating/

It's not really clear what kind of query you need to use, I'm going for 'sum(things) by (name)` to get all the 'name' things. Makes sense? But Grafana keeps showing the error: 'Template variables could not be initialized: undefined' warnings, and the templating pulldown stays empty. Anyone has more success? (it all works fine with a graphite backend)

Have a look at the Prometheus specific part of the template
documentation http://docs.grafana.org/datasources/prometheus/#templated-queries

It's basically `label_values(name, thing)`. In master there is an
additional option `query_result(<query>)` to execute any kind of
query.

Hi ,

I using Grafana 2.6 and Prometheus 0.18. I am using Docker images of these.
My data source is Prometheus.
While creating new variable in templating option , I am using query_result(query) option.

For example , I have used query_result(http_requests_total) but I am getting following error. I have tried couple of different queries but no luck

Template variables could not be initialized: parse error at char 13: could not parse remaining input "(http_requests_"...

What is the proper way to use query_result(query) option.

To my knowledge query_result was only added after 2.6. You have to
upgrade to 3.0 here.
