Hi,
I’m wondering if it’s easy to add timestamps to the mongrel log? I am
having a problem where an externally spawned application by Rails is
failing. Mongrel kindly logs the error message returned by this
application when it fails. But it doesn’t record a timestamp as to when
the error occurs, which makes it a little tricky to sync this up to my
webserver logs to figure out the execution path which is causing the
error.
Is there an easy way to add timestamping to logs in Mongrel for
exception traps? I am using a hosting service (EngineYard) so ideally
this isn’t something that requires a code change but can be done via
configuration. Though I’m sure EY will do what’s necessary to make it
happen, it’ll be better if the change is simple/low impact.
Thanks for any advice!

We are actually adding this to Mongrel. Should be out in an upcoming
release.
It involves combing through the code 
I am about 75% through.

Steve,
I just committed a change set to trunk that prepends Time.now.httpdate
to most output strings.
I am refactoring the logging to be more uniform and will be setting it
up to log using the common logfile format:

Hope this helps,

Well, he committed it to trunk, but didn’t write any tests, so what am
I supposed to do with that, really 
.

Any word on this being in an official release? We’re currently on 1.1.1,
and the timestamps don’t seem to appear, and I’m unable to find it in
any changlog for other versions.
Thanks!
I added timestamps to my mongrel logs by adding these lines to
config/environment.rb:
class Logger
def format_message(severity, timestamp, progname, msg)
time = timestamp.getutc.strftime("%Y%m%d%H%M%S")
“\n#{time}:#{severity.to_s.upcase}:#{$$}:#{msg}”
end
end
It logs messages like this:
Processing MyController#my_method (for 127.0.0.1 at 2007-12-29 14:37:54)
[POST]
20071229133754:INFO:23386: Session ID: d7022e387306cc4e5fea107080014bf1
20071229133754:INFO:23386: Parameters: {“action”=>“my_method”,
“controller”=>“my”, “id”=>“1”}
20071229133754:DEBUG:23386:ID = 1
The process id turned out to be extremely useful to debug some weird
things my application started doing when moved from the single mongrel
development environment to a multi mongrel one in production.
Furthermore, sometimes the logs from two or more requests get mixed
together (I guess that it can’t be helped) and the process id helps to
connect a log line to its request.

Any changes of being able to “pipe” log(s) to “crono/rotatelogs” like a
apache does ?

Justin,
Checkout trunk, write some tests and it’ll get pushed out. I do not have
the
time to do this right now and won’t for a few more weeks at lest.
