added tip on the Metrics page, to tell users that the Metrics page should be used with Grafana Share URL, and it's stored in local only.

NOTE: this is only a tip, no need to add a testcase.

LGTM.

BTW we stored the monitor url locally, how about turn the url as a global config setting, so that when we configed grafana start dashboard, all the user could visit the monitor page without setting the Grafana URL in setting page?

Just to make sure, does this mean store a local grafana default URL?

emm, I mean store the url in the config file(this may need manager-api's help) instead of localstorage ^_^

Got it, and if users want a more powerful dashboard, they could use Grafana directly than a single page.
