lilalo

annotate lm @ 23:6d93c5f1d0e5

Выполнен шаг (2) в плане (N05) по построению распределённой системы lilalo.

Программа lm-report разрезана на две: l3-agent и l3-frontend.
Агент выполняет анализ script-файлов и записывает
результаты анализа в файл обмена (cache).
Фронтенд читает данные из файла обмена и представляет
их в требуемом формате (в настоящий момент только html).

Сейчас взаимодействие agent'а и frontend'а выполняется так:


. ^ . +-------+ . ^^ .
/ \ | | / \
( agent )-->| cache |--->( frontend )
\ / | | \ /
' . ' +-------+ ' .. '


Добавлены файлы:
l3-agent - агент
l3-frontend - фронтенд
l3-report - замена lm-report, использующая l3-agent и l3-frontend
l3-config.pm - модуль конфигурации системы

Новые конфигурационные параметры:
cache - Путь к временному XML-файлу, предназначенному
для обмена информацией между агентом и фронтендом

cache_head_lines - Количество строк вывода команды сверху, которые
должны быть сохранены в промежуточном XML-файле

cache_tail_lines - Количество строк вывода команды снизу, которые
должны быть сохранены в промежуточном XML-файле

Устаревшие параметры:
output_mask - Использование output_mask осуждается.
Параметр будет удалён из будущих версий

Использование lm-report осуждается.
В будущих версиях программа lm-report будет удалена из дистрибутива.
Вместо неё нужно использовать l3-report.
