[System logs]: Eliminate duplicate log messages and attempt rotation more frequently (#520) * Rename 'ACSFileFormat' -> 'SONiCFileFormat' * Rename '00-acs.conf' -> '00-sonic.conf' * Add logrotate.d and systemd-journald config files to image * Log all SONiC process messages to /var/log/syslog; prevent duplicate logging to /var/log/messages * Do not redirect cron and daemon logs to their own files, let them log to /var/log/syslog * Log all teamd messages to /var/log/teamd.log; Add more SONiC program names to SONiC rules clause * Remove duplicate code by condensing quagga programs into a list; Fix teamd log rule * Kernel and LPR messages no longer getting duplicated to their own log files * Now calling logrotate every minute via cron job * Need full path to logrotate in cron job * Add '.log' suffix to wildcards, otherwise logrotate will rotate already-rotated logs (e.g., bgpd.log.1.1.1.1.1...) * Add microsecond granularity to syslog messages * Don't overwrite system crontab, instead, install additional logrotate crontab file into /etc/cron.d * Removed incomplete concept of per-process SONiC logs. We can revisit again later 2017-04-21 10:22:44 -05:00			`# Attempt to rotate system logs once per minute`
[System logs]: Fix logrotate bugs (#535) - rsyslog logs were being rotated regardless of whether they exceeded their maixmum size. This was due to "-f" flag passed to logrotate in cron job. - After rotation, /var/log/syslog was never written to again. Instead, logs were written to /var/log/syslog.1. This was due to rsyslog not properly closing the file descriptor to the pre-rotated log. - Also brought back time-related rotation via the new(er) maxsize option, which performs a boolean OR operation. If the log exceeds the maxsize OR the log hasn't been rotated in the specified, it will be rotated. Using the older size option, the time-based rotation was ignored. - Also addresses issue #528 2017-04-24 19:55:05 -05:00			`* * * * * root /usr/sbin/logrotate /etc/logrotate.d/rsyslog`
