Как подавить шумы Ubuntu 15.04 шумный системный журнал

Question 1

На Ubuntu 15.04 (яркий Vervet) /var/log/syslog является чрезвычайно шумным. Существуют сообщения каждые несколько секунд, от systemd, thermald, gnome-session. Большинство сообщений, кажется, несущественно, просто сообщения о состоянии или сообщения отладки, повторенные много раз.

Я нахожу, что это делает очень трудным использовать системный журнал для поиска и устранения неисправностей проблем, монитора для ошибок и отказов, поскольку журнал заполнен повторными блоками несущественных сообщений о состоянии от различных демонов. Там какой-либо путь состоит в том, чтобы настроить систему для отключения таких сообщений в системном журнале?Спасибо.

Например, следующий блок thermald сообщения повторяются каждые 10-60 секунд в системном журнале:

May 30 17:37:14 xxx thermald[960]: Dropped below poll threshold
May 30 17:37:14 xxx thermald[960]: thd_trip_cdev_state_reset
May 30 17:37:14 xxx thermald[960]: thd_trip_cdev_state_reset

May 30 17:37:14 xxx thermald[960]: thd_trip_cdev_state_reset index 5:rapl_controller
May 30 17:37:14 xxx thermald[960]: thd_trip_cdev_state_reset
May 30 17:37:14 xxx thermald[960]: thd_trip_cdev_state_reset index 0:Processor
May 30 17:37:14 xxx thermald[960]: thd_trip_cdev_state_reset index 4:intel_powerclamp
May 30 17:37:14 xxx thermald[960]: thd_trip_cdev_state_reset index 6:intel_pstate
May 30 17:37:14 xxx thermald[960]: thd_trip_cdev_state_reset index 5:rapl_controller
May 30 17:37:15 xxx thermald[960]: Read set point 0

Кроме того, каждый раз my-weather-indicator обновления gnome-session заполняет системный журнал следующими 150 строками сообщений о состоянии (со временем, он заполняет большую часть системного журнала):

Кроме того, gnome-session иногда выкладывает огромные блоки предупреждений относительно zeitgeist действие, например, 200-300 строк сообщений, подобных этому:

May 31 15:01:21 xxx gnome-session[1848]: ** (zeitgeist-datahub:2657): WARNING **: recent-manager-provider.vala:132: Desktop file for "file:///home/zzz/Documents/file.png" was not found, exec: google-chrome-stable, mime_type: image/png

Question 2

[Другой ответ приблизительно loglevel=warn являются неправильными. thermald только поддерживает loglevel=info и loglevel=debug, таким образом, он будет всегда регистрировать по крайней мере info и более высокие уровни. Я проверил это путем проверки исходного кода.]

Для подавления шумов thermald используйте:

/etc/rsyslog.d/99-thermald.conf

if $programname == "thermald" and ($syslogseverity-text == "debug" or $syslogseverity-text == "info" or $syslogseverity-text == "notice") then stop

Затем перезапуск rsyslog:

service rsyslog restart

Это отбросит все сообщения thermald в notice уровень или ниже, все еще регистрируя сообщения в warning уровень или выше.

можно использовать тот же основной шаблон для подавления шумов других программ к симпатии. Начальная точка для документации относительно этой функции (Выражения):

http://www.rsyslog.com/doc/expression.html

Question 3

Question 4

Для подавления my-weather-indicator шума на системном журнале можно отредактировать файл myweatherindicator.py, расположенный в /opt/extras.ubuntu.com/my-weather-indicator/share/my-weather-indicator/, и прокомментировать все операторы печати отладки автор, оставленный в коде как показано ниже...

#print('///////////////////////////////////////////////////////')
#print('///////////////////////////////////////////////////////')
#print('time.time() = %s'%int(time.time()))
#print('self.actualization_time = %s'%int(self.actualization_time))
#print('(time.time()-self.actualization_time) = %s'%int((time.time()-self.actualization_time)))
#print('self.refresh*3600 = %s'%(int(self.refresh*3600)))
#print('///////////////////////////////////////////////////////')
#print('///////////////////////////////////////////////////////')

ПРИМЕЧАНИЕ: существует больше операторов печати отладки в том файле помимо тех показанных выше, таким образом, необходимо прокомментировать всех их.

Question 5

Я предпочитаю регистрировать сообщения thermald в отдельном файле, таким образом, они не отбрасываются и не загромождают системный журнал. Поместите следующее в файл, названный/etc/rsyslog.d/10-thermald.conf (как отмечено выше его, должен быть назван с именем, запускающимся с числа меньше чем 50)

if $programname == 'thermald' then /var/log/thermald.log & stop
