Re: Logs, Timestamps

Guillaume Berche

The steno-prettify tool may be given a try to format timestamps in human
readeable dates on the vm itself . See doc I contributed at [1] for sample
invocation in-situ on the vm. I haven't tested in a while, let me know if
this still works or doc needs update (the procedure had been broken a while
ago [2]

Hope this helps,

Hi daniel ,

The logs formats are basically using log library called steno

It was mentioned that we can configure to modify the logs to a human
readable format. I never did that . I think you can have a look into it

you can also look at firehouse and nozzles project . I think that is also
use ful

tutorials on nozzle

Hi all,

Why are logs like those of the CloudController dated by machine-readable
timestamps? Are there any tools to parse CF logs in-situ?

I find it a constant source of frustration trying to debug an issue
reported by a human with a human-parseable date, putting that into a Unix
timestamp converter, searching through logs for that timestamp, then
scrolling up and down having to occasionally copy/paste a timestamp back
into a converter to see if I've gone too far away from my rough target time.

Computers are rather good at converting data formats - my brain, not so
much. Wouldn't it make more sense to have the logs human-readable by
default, and if an automated system needs to ingest those logs, let *it* do
the parsing?
