Cacti 添加 CPU 监听

Cacti版本: 0.8.8a

1. 將 http://forums.cacti.net/about29832-0-asc-135.html 网址的template下载，有1,2,4,8,12,16核心的template及script抓下來，并将 host_mib_cpu.sh 复制到 cacti 根目录下的scripts 文件夹中

2. 將template.xml 导入到cacti 主机，连上webe 管理界面，选择[Import Templates]

將下载的template都导入 => 点选浏览选择档案 => 右下方 [Import]

导入后再到 Data Templates 页面，可看到如下图

Graph Templates 会看到如下图:

制作多核心cpu使用率图表

在Management > devices > 找到要制作的主机 (范例这一台主机有1颗实体CPU，总共2核心)

在[Associated Graph Templates] 选择 [Host MIB-CPU Load 2] 点选 Add

然后回到当前页面头部，点击 [Create Graphs for this Host ]

建立完毕后，点选 Graph Management 后，选择该台主机，应该就會看到XXX-CPU Utilization – 2CPU

点选之后，可以看到该资讯每個cpu core 使用率整合在一张图表

其它备忘:

sudo cp /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.bak
sudo vim /etc/snmp/snmpd.conf
sudo service snmpd restart
snmpbulkwalk -c public -v 2c 127.0.0.1

snmpd -v # 查看当前的snmp版本

snmpd.conf

版本 5.5 的 snmpd.conf

####
# First, map the community name "public" into a "security name"

#       sec.name  source          community
#com2sec notConfigUser  default       public
# i changed at below 1 line
com2sec notConfigUser 127.0.0.1 public
####
# Second, map the security name into a group name:

#       groupName      securityModel securityName
group   notConfigGroup v1           notConfigUser
group   notConfigGroup v2c           notConfigUser

####
# Third, create a view for us to let the group have rights to:

# Make at least  snmpwalk -v 1 localhost -c public system fast again.
#       name           incl/excl     subtree         mask(optional)
view    systemview    included   .1.3.6.1.2.1.1
view    systemview    included   .1.3.6.1.2.1.25.1.1
# i changed at below 1 line
view    systemview    included   .1
####
# Finally, grant the group read-only access to the systemview view.

#       group          context sec.model sec.level prefix read   write  notif
#access  notConfigGroup ""      any       noauth    exact  systemview none none
# i changed
access  notConfigGroup ""      any       noauth    exact  all        none none

#view all    included  .1                               80
# i changed
view all    included  .1  80

版本 5.7.3 的 snmpd.conf

                                                 #  system + hrSystem groups only
view   systemonly  included   .1.3.6.1.2.1.1
view   systemonly  included   .1.3.6.1.2.1.25.1
# i add 2 line at blow 
view   systemonly  included   .1 80
view   systemview  included   .1
