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

+--------------+-----------------------+-------+-------------+------+---------------------+

| Resource ID  | Name                  | Type  | Volume      | Unit | Timestamp           |

+--------------+-----------------------+-------+-------------+------+---------------------+

| 172.16.1.212 | hardware.memory.total | gauge | 198293684.0 | B    | 2014-12-05T03:41:10 |

| 172.16.1.212 | hardware.memory.total | gauge | 198293684.0 | B    | 2014-12-05T03:21:10 |

| 172.16.1.212 | hardware.memory.total | gauge | 198293684.0 | B    | 2014-12-05T03:11:10 |

| 172.16.1.212 | hardware.memory.total | gauge | 198293684.0 | B    | 2014-12-05T02:41:10 |

| 172.16.1.212 | hardware.memory.total | gauge | 198293684.0 | B    | 2014-12-05T02:31:10 |

| 172.16.1.212 | hardware.memory.total | gauge | 198293684.0 | B    | 2014-12-05T02:21:10 |

3. Ceilometer中使用snmp新增meter

3.1Ceilomter目前支持的OID

3.2 新增OID

Pro-path/hardware/inspector/snmp.py  SNMPInspector类

#system uptime

_system_uptime_oid = ".1.3.6.1.2.1.1.3.0"

3.3 新增Mapping

Pro-path/hardware/inspector/snmp.py

‘system.uptime‘:{

            ‘matching_type‘:EXACT,

            ‘metric_oid‘:(_system_uptime_oid,str),

            ‘metadata‘:{},

            ‘post_op‘:None,

}

3.4 处理类

Pro-path/hardware/pollsters/system.py

class SystemUptimePollster(_SystemBase):

    IDENTIFIER = ‘system.uptime‘

    TYPE = sample.TYPE_GAUGE

    UNIT = ‘%‘

3.5 新增模块

/usr/lib/python2.7/site-packages/ceilometer-2014.2-py2.7.egg-info/entry_points.txt

[ceilometer.poll.central]

hardware.system.uptime = ceilometer.hardware.pollsters.system:SystemUptimePollster

3.6测试

参考1.3
