Re: Log managment
Hello,
Yes I do.
I thought this was re right thing to do for logs.
But never ending file is not safe usable. This option --log_dir need
some rework I suppose.
I will go with stdout/stderr pipeline instead (using logrotate
copytruncate to handle open file descriptors)
Thank you

Hi Damien,
do you use the `--log_dir` switch? If so, mesos is creating quite many
files in a strange format:
mesos-slave.{hostname}.invalid-user.log.INFO.20140409-155625.7545
when you forward stdout of the service to a single file and afterwards
apply simple logroate
rules, you might get nicer logs.

Re: Log managment
I've already refactored the logging, I'm redirecting stdout and stderr to a
master.log or slave.log
https://github.com/deric/mesos-deb-packaging/blob/master/mesos-init-wrapper#L109
the logrotate itself it quite simple
/var/log/mesos/*.log {
daily
missingok
rotate 30
compress
delaycompress
notifempty
}

Re: Log managment
Hello, Your point is right. however --log_dir option provide a way to display logs for uses in HTTP UI. That is not permit by tailing stdout/stderr.
