ceilometer 安裝筆記

安裝步驟

1. Installing Central Collector

每個compute node都必須安裝ceilometer然後進行配置。

3. Installing Central Agent

4. Installing API Server

The API server needs to be able to talk to keystone and ceilometer’s database

[Note] /etc/ceilometer/ceilometer.conf

meter_sceret必須修改且每一個裝設ceilometer套件的conf中的sceret值必須相同
