Find and Fill Any Gaps

Once we have telemetry in place, we can identify any gaps in our metrics, especially in the following levels of our application:

• Business level – These are metrics on business items, such as sales transactions, signups, etc.
• Application level – This includes metrics such as timing metrics, errors, etc.
• Infrastructure level – Metrics at this level cover things like databases, OS's, networking, storage, CPU, etc.
• Client software level – These metrics include data like errors, crashes, timings, etc.
• Deployment pipeline level – This level includes metrics for data points like test suite status, deployment lead times, frequencies, etc.

Application and Business Metrics

• Gather telemetry not just for technical bits, but also organizational goals, i.e. things like new users, login events, session lengths, active users, abandoned carts, etc.
• Have every business metric be actionable. And if they're not actionable, they're "vanity metrics".
• By radiating these metrics, you enable fast feedback with feature teams to identify what's working and what isn't withi
