Debian環境でacpidのログをsyslogに出力する

matoken bullseye・Debian・Linux・sid・testing

ThinkPadの電源プラグのOn/Offで以前はイベントがlogに残っていたのですが，電源管理デーモンが動いていて電源の状態が取得できる状態でもいつの頃からか記録されなくなりました．停電した時間がわかって便利だったのでログ期記録できないか確認してみました．

acpitool で電源アダプタの状態を取得
$ acpitool | grep AC
  AC adapter     : online
$ acpitool | grep AC
  AC adapter     : off-line

ThinkPadのFANを制御する方法を調べて思い出したのでacpidのmanやオプションを確認すると， -l, --logevents オプションを使うとすべてのイベントをログに出力してくれるようです．

$ /sbin/acpid -h 2>&1 | grep '\-l,'
  -l, --logevents    Log all event activity.
$ man acpid | grep -i logevents -A1
       -l, --logevents
                   This option tells acpid to log information about all events and actions.

/etc/default/acpid ファイルを編集して，acpid の起動オプションに -l を追加します．

diff --git a/default/acpid b/default/acpid
index c651a78..a6a7add 100644
--- a/default/acpid
+++ b/default/acpid
@@ -1,7 +1,7 @@
 # Options to pass to acpid
 #
 # OPTIONS are appended to the acpid command-line
-#OPTIONS=""
+OPTIONS="-l"

 # Linux kernel modules to load before starting acpid
 #

acpid を再起動してオプションがついているのを確認します．

$ sudo service acpid restart
$ sudo service acpid status

acpid に -l オプションのついている状態でsyslogをtailしながら電源を抜き差ししてみると少し可読性が悪いですがログが出力されるのがわかりました．

すべてのイベントが出力されるので，ボリュームや，輝度の調整でもこのように書き出されます．

以前よりログが冗長で可読性が悪いですがとりあえず動作しました．これで停電が発生したときに停電発生時間や，短い停電であれば停電間隔が確認できます．
