@rakyll CPA (critical path analysis)
@rakyll discover the critical paths make them reliable and fast
make them debuggable
@rakyll How do we get there? (tracing, events, logs)
@rakyll Why? Why? Why? Why? Why?
@rakyll GET /timeline edge-lb sched api-server auth.Auth cache.Get mysql.Query user.Profile
cache.Get mysql.Query images.Filter blobstore.Get
@rakyll bare metal kernel network stack cloud stack libraries frameworks
your code
@rakyll GET /timeline edge-lb sched api-server auth.Auth cache.Get mysql.Query user.Profile
cache.Get mysql.Query images.Filter blobstore.Get not my fault
@rakyll GET /timeline auth.Auth cache.Get mysql.Query user.Profile cache.Get mysql.Query images.Filter
blobstore.Get cache.Get mysql.Query blob.Get where is the source code?
@rakyll GET /timeline auth.Auth cache.Get mysql.Query user.Profile cache.Get mysql.Query images.Filter
blobstore.Get cache.Get mysql.Query blob.Get who to call?
@rakyll GET /timeline auth.Auth cache.Get mysql.Query user.Profile cache.Get mysql.Query images.Filter
blobstore.Get cache.Get mysql.Query blob.Get give me the logs, runtime events, profiles...
@rakyll Challenges...
@rakyll This is an organizational problem. CHALLENGE #1:
@rakyll Engineers don’t know where to start. CHALLENGE #2:
@rakyll Infra is still a blackbox. CHALLENGE #3:
@rakyll Instrumentation is expensive. CHALLENGE #4:
@rakyll Dynamic capabilities are underestimated. CHALLENGE #5:
@rakyll
@rakyll A tool to close knowledge gaps (which we don’t
talk about)
