最近有需求统计ES存储容量，之前用PHP实现的，考虑到以后可能会经常写脚本查询，故用python写了一个脚本，代码如下：

import urllibimport urllib2import syses_service_addr = sys.argv[1] url = "http://" + es_service_addr + "/_cat/indices?v";req = urllib2.Request(url)res_data = urllib2.urlopen(req)res = res_data.read() list = res.split('\n') title = list[0].split()length = len(list)data = list[1:length]map={}for i in title: map[i] = title.index(i)capacity_used = 0; for i in data: value = i.split() l = len(value) if l > 0 : store_size = value[map['store.size']].lower() if "k" in store_size: capacity_used += int(store_size[:-1]) * 1024 elif "m" in store_size: capacity_used += int(store_size[:-1]) * 1024 * 1024 elif "g" in store_size: capacity_used += int(store_size[:-1]) * 1024 * 1024 * 1024 elif "p" in store_size: capacity_used += int(store_size[:-1]) * 1024 * 1024 * 1024 * 1024 elif "p" in store_size: capacity_used += int(store_size[:-1]) * 1024 * 1024 * 1024 * 1024 * 1024 else: capacity_used += int(store_size[:-1]) print str(capacity_used) + " Bytes"

背景：

通过ES 查询的结果如图所示，脚本实现的作用就是统计store.size 的值。

以上这篇Python 脚本获取ES 存储容量的实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
