具有zabbix-api值历史记录的输出

Question

我试图用hostid -> itemid -> history API捕获以下序列，但它没有向我返回任何内容。我需要这个脚本来返回ZABBIX收集的最后一个值​​，包括item id + hostname

脚本

from zabbix.api import ZabbixAPI
from datetime import datetime
import time

zapi = ZabbixAPI(url='http://192.168.1.250/zabbix', user='Admin', password='zabbix')

fromTimestamp = int(time.mktime(datetime.now().timetuple()))
tillTimestamp = int(fromTimestamp - 60 * 60 * 1)  # 1 hours

# Get only the host of the specified hostgroup
hosts =  zapi.host.get(groupids='15',output='extend')

for host in hosts:
    items = zapi.item.get(itemid='28689', host=host['host'], output='extend' )
    for item in items:
        values = zapi.history.get(itemids=item['itemid'], time_from=fromTimestamp, time_till=tillTimestamp, output='extend')        
        for historyValue in values:
            print(host['host'],item['itemid'],historyValue['value'])

输出

什么都没有回报我

期望输出

'host','28689','84'
'host','28689','82'
'host','28689','85'
'host','28689','83'

您的代码中有一些问题(静态itemid、history.get中缺少的参数等等)，我将尝试总结所有内容。

您是通过静态主机组id进行筛选的，因此我假设您有多个主机，并且需要每个主机的一个特定项的值，如下所示：

• 主机组: MyHostGroup
• 成员: host01，host02，host03
• 项目感兴趣: ICMP Loss

输出应该类似于：

Timestamp  Hostname   ItemID   ICMP Loss
xxxxxx1    host01     10011    0
xxxxxx2    host01     10011    10
xxxxxx3    host01     10011    10
xxxxxx4    host01     10011    15

xxxxxx1    host02     10026    100
xxxxxx2    host02     10026    100
xxxxxx3    host02     10026    100
xxxxxx4    host02     10026    100

xxxxxx1    host03     10088    0
xxxxxx2    host03     10088    10
xxxxxx3    host03     10088    0
xxxxxx4    host03     10088    0

一个有效的python实现：

groupFilter = {'name': 'MyHostGroup'}
itemFilter = {'name': 'ICMP Loss'}

# Get the hostgroup id by its name 
hostgroups = zapi.hostgroup.get(filter=groupFilter, output=['groupids', 'name'])

# Get the hosts of the hostgroup by hostgroup id
hosts = zapi.host.get(groupids=hostgroups[0]['groupid'])

for host in (hosts):
    # Get the item info (not the values!) by item name AND host id
    items = zapi.item.get(filter=itemFilter, host=host['host'], output='extend', selectHosts=['host', 'name'])

    # for loop - for future fuzzy search, otherwise don't loop and use items[0] 
    for item in items:
        # Get item values
        values = zapi.history.get(itemids=item['itemid'], time_from=fromTimestamp, time_till=tillTimestamp, history=item['value_type'])

        for historyValue in values:
            print( ......... ) # format here your output, values are stored in historyValue['value']
