[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]: Improvements to prevent filling /var/log partition (#865) - Force log rotation at size thresholds only (no longer also rotating logs daily), allowing for more consistent archived log size - Eliminate remaining duplicate log messages - Cron facility now only logs to cron.log (was also logging to syslog) - Debug, mail, news and user log facilities only log to syslog; no longer creating separate log files for these facilities - Cron job that calls logrotate every minute now uses the main /etc/logrotate.conf file so as to check/rotate all logs every minute, not just the logs specified in the rsyslog file. Also redirecting output of this command to /dev/null to prevent "(CRON) info (No MTA installed, discarding output)" messages in cron.log due to lack of a mail service - Delete archive files based on remaining /var/log partition space. Note that this solution currently requires a minimum /var/log partition size of 32MB to function correctly - Update sonic-sairedis and sonic-swss submodules to incorporate recording file name changes - Add .screen file to .gitignore (unrelated) 2017-08-10 18:24:57 -05:00			`* * * * * root /usr/sbin/logrotate /etc/logrotate.conf > /dev/null 2>&1`
