获取Python和Zabbix API中的问题描述

Question

我使用trigger.get方法获取Zabbix监控中的所有问题：

trigger = zapi.trigger.get (triggerids=problem['objectid'], selectHosts='extend')

而且它工作得很好。但我得到了一些回应，例如：

'description': '{HOST.NAME} ( {ITEM.VALUE1} ) Lack of free swap space'

或

'description': 'DBM {HOST.NAME} ORA_ERR_DETAILS: {ITEM.VALUE1}'

现在我想得到value“ITEM.VALUE1”

他应该使用什么方法以及如何使用

以更具描述性的方式：

我的程序返回值：

'{HOST.NAME} ( {ITEM.VALUE1} ) Lack of free swap space' 

我可以获取“{HOST.NAME}”，但无法获取“{ITEM.VALUE1}”

我希望：

Host005.domain.com ( 42.52 % ) Lack of free swap space

Answer 1

您可以这样指定所需的字段

answer = z.do_request('apiinfo.version')

用JSON回复：

{u'jsonrpc': u'2.0', u'result': u'3.0.2', u'id': u'1'}

python脚本的答复：

print "Version:",answer['result']
Version: 3.0.2

Answer 2

多亏了西蒙的提示，问题解决了

运行良好的代码：

#!/usr/bin/env python
# -*- coding: utf-8 -*-

"""
Get history values for specific items in a time range:

# ./getItemHistoryByName.py -H some-host  -I "ICMP response time" -f "26/6/2018 16:00" -t "27/6/2018 23:59"
