[Comm] IPMI monitoring daemon

[Comm] IPMI monitoring daemon

[Gulay Boris]

У меня сервер поддерживает IPMI. Я хотел бы, чтобы кто-нибудь периодически
запрашивал данные мониторинга (как минимум, температуру и скорости
вентиляторов) и слал мне сообщение, если что-то не так. Скажу даже больше -
в IPMI есть лимиты, которые влияют на статус датчика (Normal, Crytical и
т.п.), было бы здорово эти лимиты проверять и слать сообщение при
возникновении проблем.
То есть я хочу что-то вроде smartd из комплекта smarttools для IPMI.
Подскажите, пожалуйста.

Добрый день.

Я применяю вот такой (немножко допиленный) скрипт для nagios:

#!/usr/bin/perl

# Nagios plugin for IPMI sensors status checking.
# Especially useful on Dell Poweredge servers, and others that
# implement the Intelligent Platform Management Interface (IPMI)
# interface.

# Tested against the 1850, 1950, 2850, 2950, SC1420, PE830 BMCs

failing

Гляньте ещё ipmievd(8) из ipmitool, он умеет не в сислог,
а в stdout/stderr события валить.
