nrpe: команда mysql_check не определена

Question

Я пытаюсь проверить mysql и tomcat на localhost. В основном мне нужно проверить порты, чтобы увидеть, что приложения слушают. У меня установлены плагины nrpe и nagios. Я пытаюсь использовать nrpe для проверки mysql на localhost, но nagios показывает эту ошибку: NRPE: команда check_mysql не определена

Любая идея, пожалуйста?

Answer 1

Вы должны определить check_mysql определение команды для NRPE.

Отредактируйте свой nrpe.cfg.

vim /etc/nagios/nrpe.cfg

Добавить запись команды для check_mysql указывая на путь check_mysql плагин:

command[check_mysql]=/usr/lib64/nagios/plugins/check_mysql

Перезапустите nrpe:

service nrpe restart
