We want to get baseline product health metrics on our RecentActivity module in the PersonalDashboard extension.

In order to get this, we will follow the xLab measure product health workflow.

The events that we would like to instrument and capture are:

• Click through rate on each diff in the Recent Activity module
• Click through rate on the ‘recent changes’ link in Recent Activity

Acceptance Criteria:

• Use xLab SDKs to instrument the above events
• Ensure the events are being sent correctly
