sample list

然后就是sample list的使用 -m 指定是哪个meter -q 查询 resource 指定刚才 meter-list里面查询出来的resource。

命令行参数指定 tips :

1. 在-q中指定多个过滤条件的方法：用分号连接，各个过滤条件之间是与的关系。 若要用并关系或者按counter_volume取值查询，目前估计只能用query-sample 这个CLI

   ceilometer …… -q "resource=xxx ; timestamp<yyy"

2. 目前只有在访问meter表的代码里用到get_meter方法中才支持通配, 即$ ceilometer meter-list -q resource=通配表达式其余的-q参数中虽然指定resource的值，但是最后没有落到get_meter方法来处理，还是无法通配。

3. 带 -q <QUERY>的后接参数不同命令支持的-q范围不一样，大抵因为访问的表不同。

4. -q 后接参数中的resource=xxx，其中的xxx是uuid+维度名的形式

5. -m 后接的meter_name，只是维度名，不含uuid

6. statistics指定多个groupby参数作为分组依据的方法：

   ceilometer statistics …… -g "project_id" -g "user_id"

1. statistics对于cardinality公式的参数给法示例： ceilometer statistics -m cpu -a 'cardinality<-project_id'

2. query-samples 对于counter_volume（具体的采样值）的指定时，数值不能加双引号不能加双引号不能加双引号。

3. search_offset这个过滤参数的含义： 该参数指定了以分钟为单位的偏移值，必须和timestamp参数一起搭配使用，举例如

  ceilometer sample-list -q “timestamp<xxx；search\_offset=9"

那么就会把这个timestamp指定的时间之后的9分钟内的样本一起返回。
