Openstack-Ceilometer-SNMP的使用

標籤：style   blog   io   ar   color   os   使用   sp   for   

 

1. 物理伺服器配置1.1安裝

#yum install -y net-snmp net-snmp-utils

1.2      配置

複製【附件】中snmpd.conf檔案到/etc/snmp/目錄下。（原有的重新命名，儲存）

關閉selinux和防火牆

#setenforce 0#vi /etc/sysconfig/selinux 修改為：SELINUX=disabled#service snmpd start#chkconfig snmpd on

2. 在Ceilometer中測試

添加一個已存在的meter

2.1在pipline.yaml新增meter

增加一個記憶體meter,/etc/ceilometer/pipline.yaml

- name: hardware_memory_sourceinterval: 60meters:- "hardware.memory.*"resources:- snmp://172.16.1.212sinks:- meter_sink

2.2重啟ceilometer

#systemctl restart openstack-ceilometer-central.service

2.3 擷取meter

#ceilometer meter-list | grep hardware#ceilometer sample-list -m hardware.memory.total

樣本

3.2 新增OID

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

#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 處理類

class SystemUptimePollster(_SystemBase):    IDENTIFIER = ‘system.uptime‘    TYPE = sample.TYPE_GAUGE    UNIT = ‘%‘

3.5 新增模組

/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
