Use of OPENSTACK-CEILOMETER-SNMP

1. Physical Server Configuration 1.1 installation

# Yum install-y net-snmp net-snmp-utils

1.2 Configuration

Copy the snmpd.conf file in the "attachments" to the/etc/snmp/directory. (original rename, save)

Turn off SELinux and firewalls

# Setenforce 0 # Vi/etc/sysconfig/selinux modified to: SELINUX=disabled#service snmpd start#chkconfig snmpd on

2. Testing in Ceilometer

Add a meter that already exists

2.1 New meter in Pipline.yaml

Add a Memory Meter,/etc/ceilometer/pipline.yaml

-meters:"hardware.memory.*"resources:-snmp:// 172.16.1.212Sinks:-Meter_sink

2.2 Restart Ceilometer

# systemctl Restart Openstack-ceilometer-central.service

2.3 Get Meter

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