Subject: [make-initrd] [PATCH v1 00/11] Add accounting feature
Date: Thu, 15 Jun 2023 19:59:09 +0200
Message-ID: <cover.1686851829.git.gladkov.alexey@gmail.com> (raw)
Привет!
Я написал фичу для отладки initramfs. Фича добавляет в бэкграунде процесс
аккаунтинга, который запускается на самых ранних этапах загрузки и собирает
данные о процессах. Перед запуском системного init формируется отчёт по
интересующим критериям.
Фича предназначена для отладки в тестах. Я хочу поразбираться, кто тратит больше
всего времени или cpu/memory. А то сейчас очень профилировать очень сложно.
Получилось сложнее, чем обычный acct(2), потому что я хотел получать не только
comm процесса т.к. у шелльных скриптов это bash. Хотелось максимально поймать
полный cmdline выполняемой программы.
Alexey Gladkov (11):
