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

示例
