+# Development Report for Mar 17, 2017
+
+## Testing Plan
+
+Thanks to @gianarb for starting the discussion around a test and CI plan for containerd.  We want to make sure that users of containerd can feel secure depending on containerd; having a solid test plan is a must.
+
+Testing a project like containerd is always a challenge because of the systems that it needs to support. ARM, Windows, Linux, and Power (as well as many more variations) are all examples of platforms that we support today and will need a CI.
+
+You can view the issue and contribute to the testing plan [here](https://github.com/docker/containerd/issues/634).
+
+## Windows Runtime
+
+Work has started on porting over the Windows execution code.  There is still a lot of testing to do after the port but a PR should be coming soon.
+
+## Metrics
+
+We started the work to get container level metrics exported over prometheus.  You can see the initial output here:

+
+The `id` label will be the id of the container so users can filter on the metrics for only the containers that they care about.
+
+The frequency of metric collection is configurable via the prometheus scrape time.  Every time the `/metrics` API is hit, that is when container metrics are collected.  There is no internal timer in containerd, you only pay the cost of collecting metrics when you are asking for them.  If you never ask for metrics the collection never happens.
+
+There should be a PR up soon so that we can discuss the metrics and label names.
