Cloud Foundry Logging Proposal

Log Format

Each log line corresponds to a line of JSON. This is backward compatible with the existing steno output.

Common among all log-level formats:

{
  timestamp: TIMESTAMP, // formatted as fmt.Sprintf("%.9f", time.Now().UnixNano()) / 1e9)

Decouple Compare and Swap from the serialized Value

if we modify storeadapter#compareAndSwapByIndex to return the new index, we can use this mechanism for our lifecycle/state machines:

type StoreAdapter interface {
  CompareAndSwapByIndex(prevIndex uint64, newNode StoreNode) (newIndex uint64, err error)
}

This would allow our state machines to continue, even if the values changed (provided all versions of the model have a StoreIndex field that we can use). Doesn't solve the issue of our processes expecting the data to be in a different format that the model they currently have, but it does prevent model changes from messing up the state machine.

Metrics

Questions

• where is time recorded?
• how do we unit test what values we have recorded?

Notes

• instrumentedResponseWriter does not support the http.CloseNotifier interface

This is a minimal-ish set of instruction to set up a freshly imaged OS X workstation for working on Diego. If you've already used the Pivotal sprout recipes to provision your machine, you might have a bad time.

Pivotal Workstation Conveniences

These are nice for the core developer team, feel free to skip this section:

• Download Chrome using Safari, and install it.
• Download Wraparound from the web.
• Download ShiftIt.zip from github.com/onsi/shiftit.
• Get Flycut from the App Store.
