Rsyslog missing log

Vote 0 Votes

比較新的 Linux 都是使用 systemd journal 來處理 log, 其預設是有 Rate Limit 的,
若系統的 Log 量很多, 有可能會被達到限制條件而被過濾掉,
若觀察到 Log 有時卡住沒有新的出現, 可能就是這個狀況
journalctl -u systemd-journald
若有看到 Suppressed xxx messages 就表示有被濾掉

取消 Rate Limit 限制

/etc/systemd/journald.conf 加入

/etc/rsyslog.conf 加入
$imjournalRatelimitInterval 0
$imjournalRatelimitBurst 0

systemctl restart systemd-journald
systemctl restart rsyslog
