问题描述
我正在编写一个可以进行一些分析的 Python 脚本.此脚本使用以下 zabbix api 获取项目的最后一个值:
Im working on a python script that does some analysis. This script uses the following zabbix api to get the last value of an item:
getlastvalue = {
"jsonrpc":"2.0",
"method":"item.get",
"params":{
"output":"extend",
"hostids":"10084",
"search":{
"key_":"vfs.fs.size[/var/log,used]"
},
"sortfield":"name"
},
"auth":mytoken,
"id":1
}
我的脚本分析响应并产生此反馈:
My script analyzes the response and produces this feedback:
LatestValue:499728384 LatestValueEpoch:1553573850 HowLongAgo:33secs ItemID:51150
现在,我想知道该项目 24 小时前的价值是多少……意思是从 LatexValueEpoch 时间算起 24 小时.这是我遇到问题的地方.我想我可能没有使用正确的 json.但这是我一直在使用的:
Now, I wish to know what the value of the item was 24 hours ago...meaning 24 hours from the LatestValueEpoch time. This is where Im having an issue. I think I may not be using the right json. But here's what I've been using:
historyget = {
"jsonrpc":"2.0",
"method":"history.get",
"params":{
"output":[
"itemid",
"extend"
],
"time_from":"",
"time_to":"",
"itemids":[
"51150"
]
},
"auth":mytoken,
"id":1
}
我在脚本中替换了 time_from
和 time_to
的值以反映昨天的时间(24 小时前正好从当前时间开始).但我得到的回应不是我想要的.我在这里做错了什么?
I replace the value of time_from
and time_to
in my script to reflect yesterday's time (24 hours ago exactly from the current time). But the response I get isnt what I want. What am i doing wrong here?
推荐答案
你必须使用 history.get
API 调用.
You have to use the history.get
API call.
使用 time_from
、time_till
和 limit
的组合,您应该相应地获得一组值或单个值.
Using a combination of time_from
, time_till
and limit
you should get an array of values or a single value accordingly.
重要:您必须在 history.get
调用中指定 history
参数(要返回的历史对象类型):我通常会一个 item.get
来捕捉我需要的东西,然后是一个 history.get
.
Important: You have to specify the history
parameter (History object types to return) in the history.get
call: I usually make an item.get
to catch the stuff I need, then an history.get
.
我作为帮手编写的一个小python示例:
A small python sample I wrote as a helper:
#!/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"
ItemID: 77013 - Item: ICMP response time - Key: icmppingsec
1530021641 26/06/2018 16:00:41 Value: 0.1042
1530021701 26/06/2018 16:01:41 Value: 0.0993
1530021762 26/06/2018 16:02:42 Value: 0.1024
1530021822 26/06/2018 16:03:42 Value: 0.0966
