Where did the v1 host breakdown go?

RPM Version 1 supported a breakdown of metrics for each host in your account. The Version 2 interface changed to emphasize the application, and the host-centered views were removed. Here's how to get per-host metrics in v2:

Option 1:

The v1 pages are still around, but take a few clicks to get back to. Look for "Back to v1" links near the top-right of the page. These will stick around for a while, but not forever, as we eventually will transition fully to v2.

Option 2:

Create virtual applications that map to your hosts. In the newrelic.yml config file, you can set the app_name parameter to a semicolon-delimited list of app names. The agent will report metrics to each name in the list.

For example, in production01.example.com's newrelic.yml file:

app_name: Awesome Widgets; production01.example.com

And on production02:

app_name: Awesome Widgets; production02.example.com

All agents using either of these config files will report their metrics into two buckets: one for their host and another for the Awesome Widgets app. When looking at the "app" named production01.example.com in the v2 UI, you'll get all the same breakdowns as for a normal app, but the numbers will be those for only the selected host.

You can use this technique to aggregate metrics from multiple applications running on a single host, as well. Just add the host's name (or any name you'd like to identify the host) to the newrelic.yml for each app.
