プラグイン
yum install gcc-c++
sensu-install -P disk-checks,cpu-checks,io-checks,hardware,postfix
sensu-install -P snmp,http,mysql,redis,rabbitmq
sensu-plugins-http で gcc-c++ パッケージが必要。
設定
cp /etc/sensu/config.json{.example,}
sed -i '/"host"/ s/localhost/127.0.0.1/' /etc/sensu/config.json
sed -i.org 's/Site 1/Sensu Server/;s/api1.example.com/127.0.0.1/' /etc/sensu/uchiwa.json
sed -i '8,17d' /etc/sensu/uchiwa.json
localhost の指定だとうまく動作しない。
