Openstack-Ceilometer-SNMP的使用
1. 物理服务器配置
1.1安装
#yum install -y net-snmp net-snmp-utils
1.2 配置
复制【附件】中snmpd.conf文件到/etc/snmp/目录下。（原有的重命名，保存）
关闭selinux和防火墙
#setenforce 0 #vi /etc/sysconfig/selinux 修改为：SELINUX=disabled #service snmpd start #chkconfig snmpd on
2. 在Ceilometer中测试
添加一个已存在的meter
2.1在pipline.yaml新增meter
增加一个内存meter,/etc/ceilometer/pipline.yaml
- name: hardware_memory_source interval: 60 meters: - "hardware.memory.*" resources: - snmp://172.16.1.212 sinks: - meter_sink
2.2重启ceilometer
#systemctl restart openstack-ceilometer-central.service
2.3 获取meter
#ceilometer meter-list | grep hardware #ceilometer sample-list -m hardware.memory.total
