Не работают плагины Munin - mysql_qcache

su -m munin -c /usr/local/bin/munin-cron

# head -n 2 /usr/local/etc/munin/plugins/mysql_qcache

#!/usr/bin/perl

This is perl 5, version 24, subversion 1 (v5.24.1) built for x86_64-linux-gnu-thread-multi

Dram:
Посмотрел у плагинов мускуля которые работают и у тех которые не работают - написано одинаково:


команда что вы написали на Дебиан не выполняется

В логах мунина за сегодня по запросу "qcache" ничего не нашло.

Dram:
Ваш файл не работает, ошибка такая: (вероятно перл виноват?)

[mysql*]

user root

env.mysqlconnection DBI:mysql:mysql;host=localhost;port=3306

Dram:
Есть два пути у меня в дебиане:

1. /usr/local/etc/ дальше пусто
2. /etc/munin/plugin-conf.d с файлом munin-node

в нем прописано:

[mysql*]
env.mysqlopts -u root -pПАРОЛЬ
env.mysqladmin /usr/bin/mysqladmin
env.mysqlshow /usr/bin/mysqlshow
env.mysqluser root
env.mysqlpassword ПАРОЛЬ
