docker-stats 0.0.3

Docker统计

docker stats wrapper，它用json打印输出

用法

从pypi安装并运行

usage: docker-stats [-h] [-a] [container [container ...]]

docker stats, json way

positional arguments:
  container   IDs or NAMEs of desired containers

optional arguments:
  -h, --help  show this help message and exit
  -a, --all   get stats of all available containers
  -n, --normalize   try to normalize stats

标准化

Docker统计的原始输出如下：

{"my_container":{"blkio_stats":{"io_merged_recursive":[],"io_queue_recursive":[],"io_service_bytes_recursive":[{"major":253,"minor":5,"op":"Read","value":7020544},{"major":253,"minor":5,"op":"Write","value":0},*SNIP*]}}}

正如我们可以提到的，在键io_service_bytes_recursive内有一个数组对象，并且该数组的每个元素都是在值内用键op展开的json。这种行为可能发生在其他钥匙上。 用键--normalize调用的docker stats尝试将其jsonify为：

{"my_container":{"blkio_stats":{"io_merged_recursive":[],"io_queue_recursive":[],"io_service_bytes_recursive":{"Read":{"major":253,"minor":5,"value":7020544},"Write":{"major":253,"minor":5,"value":0},*SNIP*}}}}
