5 minutes after we first met

How I use this

It works great

No errors… Data shows up where its supposed to

But it feels slow

How do I find out where the problem is…

…when there is no problem

Three pillars of observability • Metrics • Spotting trends/patterns • Send alerts • Catch known unknowns • Logs • Traces

Relevant metrics to help me • Total ounces eaten • Performance timings for each function

Three pillars of observability • Metrics • Logs • Structured & easy to grep • Find the details of an event • Catch the unknown unknowns • Traces

Relevant log lines for me • Function entry and exit timestamps, total time • What is being collected by each step

Three pillars of observability • Metrics • Logs • Traces • Request-based • Follow activity across function and service • Answers “Where?” and “How long?”

But I want more visibility into what is going on

Time wasted getting static values

But I need more data
