2 使用控制台获取域(AZ)监控信息 使用如下命令可以获取当前openstack的所有可用域。

3 使用 openstack python-api 获取域监控信息 程序代码如下
#!/usr/bin/python
-- coding: utf-8 --
#imports import json from optparse import OptionParser from novaclient import client as noclient from novaclient import utils #登录及授权 keystone {} keystone[‘os_username’]‘admin’ keystone[‘os_password’]‘keystone’ keystone[‘os_auth_url’]‘http://lb-vip:5000/v2.0/’ keystone[‘os_tenant_name’]‘admin’ nova_client noclient.Client(2, keystone[‘os_username’], keystone[‘os_password’], keystone[‘os_tenant_name’], keystone[‘os_auth_url’]) def main(): #获取云平台整体信息并打印 total_info nova_client.hypervisor_stats.statistics()._info.copy() print “total_info_vcpus:”, total_info[“vcpus”] print “total_info_vcpus_used:”, total_info[“vcpus_used”] print “total_info_memory_mb:”, total_info[“memory_mb”] print “total_info_memory_mb_used:”, total_info[“memory_mb_used”] print “total_info_running_vms:”, total_info[“running_vms”] #获取域列表信息 aggregates nova_client.aggregates.list() for aggregate in aggregates: #初始化每个域的资源统计变量 vcpus 0 vcpus_used 0 memory_mb 0 memory_mb_used 0 running_vms 0 #获取每个aggregate信息并保存对应的hostscomputer节点列表 aggregate_info aggregate._info.copy() print aggregate_info[“id”], aggregate_info[“name”], aggregate_info[“availability_zone”], aggregate_info[“hosts”] aggregate_hosts aggregate_info[“hosts”] #循环计算节点保存相关资源信息 for aggregate_host in aggregate_hosts: hypervisor_info utils.find_resource(nova_client.hypervisors, aggregate_host)._info vcpus vcpus hypervisor_info[“vcpus”] vcpus_used vcpus_used hypervisor_info[“vcpus_used”] memory_mb memory_mb hypervisor_info[“memory_mb”] memory_mb_used memory_mb_used hypervisor_info[“memory_mb_used”] running_vms running_vms hypervisor_info[“running_vms”] #打印域资源信息print vcpus:, vcpusprint vcpus_used:, vcpus_usedprint memory_mb:, memory_mbprint memory_mb_used:, memory_mb_usedprint running_vms:, running_vmsif name “main”: main() 执行该程序后可以获取各个域节点的信息
total_info_vcpus: 288 total_info_vcpus_used: 172 total_info_memory_mb: 1546440 total_info_memory_mb_used: 584704 total_info_running_vms: 42 1 IMSRCS IMS [u’computer04’, u’computer03’, u’computer08’] vcpus: 144 vcpus_used: 84 memory_mb: 773220 memory_mb_used: 243200 running_vms: 20 4 paas paas [u’computer07’, u’computer05’, u’computer06’] vcpus: 144 vcpus_used: 88 memory_mb: 773220 memory_mb_used: 341504 running_vms: 22 经过适当的计算我们就可以获取各个域分配及使用比例等信息。 上面我们就使用 python-api 打印出了所有需要的信息但是对于监控来说我们需要提取的是各个监控项的信息这样才能方便的搜索和做图表展示下面我们讨论结合zabbix进行相关信息的监控。4 结合zabbix获取域相关监控信息 4.1 获取可用域信息列表 上面我们已经获取了所有的可用域信息但对于zabbix来说我们还需要返回固定格式的数据供zabbix进行解析
#!/usr/bin/python
-- coding: utf-8 --
#imports import json from optparse import OptionParser from novaclient import client as noclient from novaclient import utils #登录及授权 keystone {} keystone[‘os_username’]‘admin’ keystone[‘os_password’]‘keystone’ keystone[‘os_auth_url’]‘http://lb-vip:5000/v2.0/’ keystone[‘os_tenant_name’]‘admin’ nova_client noclient.Client(2, keystone[‘os_username’], keystone[‘os_password’], keystone[‘os_tenant_name’], keystone[‘os_auth_url’]) def main(): r {“data”:[]} aggregates nova_client.aggregates.list() for aggregate in aggregates: aggregate_info aggregate._info.copy() r[‘data’].append( {“{#NAME}”:aggregate_info[“name”]} ) print(json.dumps(r, indent2, sort_keysTrue, encoding“utf-8”)) if name “main”: main() 执行后返回的结果如下,可以通过供zabbix自动发现模版使用
{ “data”: [ { “{#AVAILABLE_ZONE}”: “IMS”, “{#NAME}”: “IMSRCS” }, { “{#AVAILABLE_ZONE}”: “paas”, “{#NAME}”: “paas” } ] } 4.2 zabbixItem及自动发现LLD配置 云平台整体信息Item设置如下
openstack.total[vcpus] openstack.total[vcpus_used] openstack.total[memory_mb] openstack.total[memory_mb_used] openstack.total[running_vms] 获取{#NAME}后就可以根据监控项获取对应的监控内容了zabbix自动发现自动发现key设置如下
openstack.system.discovery discovery下设置监控Item,key设置如下
openstack.zone[hosts,{#NAME}] openstack.zone[vcpus,{#NAME}] openstack.zone[vcpus_used,{#NAME}] openstack.zone[memory_mb,{#NAME}] openstack.zone[memory_mb_used,{#NAME}] openstack.zone[running_vms,{#NAME}] 其中{#NAME}为第一步的脚本中返回的可用域对应的aggregate相关信息。
4.3 zabbix-agent配置与对应的脚本 对应的zabbix-agent.conf配置如下
/etc/zabbix/zabbix_agentd.d/userparameter_openstack-system.conf
UserParameteropenstack.system.discovery,python /etc/zabbix/zabbix_agentd.d/openstack-system.py --item discovery UserParameteropenstack.total[],python /etc/zabbix/zabbix_agentd.d/openstack-system.py --item total --moniter $1 UserParameteropenstack.zone[],python /etc/zabbix/zabbix_agentd.d/openstack-system.py --item $1 --aggregate $2 对应的zabbix自动发现的监控脚本如下
/etc/zabbix/zabbix_agentd.d/openstack-system.py
