It looks like you are sending invalid queries to graphite. Try removing the randomWalk function (it is just there to test graphite). You can remove the function by clicking its name and then the x icon. Or just remove the all the randomWalk queries and then click the Add query button to start with a new query.

Grafana visualizes the graphite expression in a way that is more easy to view and edit for example.

prod.apps.*.stats.count summarize(1h, sum) aliasByNode(2)

Is actually:

aliasByNode(summarize(prod.apps.*.stats.count, '2h', 'sum'), 2)

You can click the pen icon to view the underlying textual graphite target. In the case your case there is one graphite target that looks like this:

randomWalk(carbon.undefined,'random walk')

This is not valid, randomWalk does not take 2 parameters.

Thanks I removed the function and add a new query, it work now :) But when i refresh the web page (F5) or open the page by other browser,it become the test page agian. Can i save the new query page ?

Yes, you the save icon in the menu to open the save dropdown. Here you can save to Elasticsearch or export to json file.
