Adding timestamps to supervisord logs

loggingsupervisordtimestamp

Is it possible to let supervisord add timestamps to the outputs in stdout_logfile and stderr_logfile? I couldn't find it anything about that in the documentation.

My $0.02. If you are running in Docker, then let the docker container capture stdin/stdout and capture timestamps that way. If not, send output to syslog and let either systemd or rsyslog append their timetstamps. Unless your system is heavily loaded (and rsyslog/systemd cannot keep up), this should get you what you need.

See this answer for docker.

See the official documentation for rsyslogd and search for "precision". For some vendors (RedHat, Ubuntu) this may already be enabled by default.

See this nice tutorial on using journalctl with systemd.

Rsync : copying over timestamps only

Using -t (preserve timestamps) and --size-only will only compare files on size. If the size matches, rsync will not copy the file but since -t is specified, it will update the timestamp on the destination file without recopying it.

Make sure to not use -u (update) as this will skip files that already exist and completely skip updating the timestamp.

I had the problem of originally not using rsync to copy a bunch of files to a new drive, and therefore the timestamps were updated to current time. I used the command below to sync everything correctly in a decent amount of time:

rsync -vrt --size-only /src /dest

Reload signal for UWSGI when using Supervisord

stopsignal

    The signal used to kill the program when a stop is requested. 
    This can be any of TERM, HUP, INT, QUIT, KILL, USR1, or USR2.

    Default: TERM

    Required: No.

    Introduced: 3.0

stopsignal=HUP is what you're looking for:

[program:uwsgi]
user = uwsgi
command=/usr/sbin/uwsgi ...
autostart=true
autorestart=true
stderr_logfile = /var/log/uwsgi/err.log
stdout_logfile = /var/log/uwsgi/out.log
stopsignal=HUP
