安装net-snmpd和mrtg手册
1. 安装和配置net-snmpd
首先使用ports安装net-snmpd，使用如下命令：
cd /usr/ports/net/net-snmp
make install clean
安装完毕之后使用如下命令对snmpd进行配置：
snmpconf -g basic_setup
将会出现一个询问菜单，按如下步骤进行回答：
- Do you want to configure the information returned in the system MIB group (contact info, etc)? (default = y): y
- The location of the system: Bei Jing, China
- The contact information: master@xxx.com
- Do you want to properly set the value of the sysServices.0 OID (if you don't know, just say no)? (default = y): y
- does this host offer physical services (eg, like a repeater) [answer 0 or 1]: 1
- does this host offer datalink/subnetwork services (eg, like a bridge): 0
- does this host offer internet services (eg, supports IP): 1
- does this host offer end-to-end services (eg, supports TCP): 1
- does this host offer application services (eg, supports SMTP): 1
- Do you want to configure the agent's access control? (default = y): y
- Do you want to allow SNMPv3 read-write user based access (default = y): n
- Do you want to allow SNMPv3 read-only user based access (default = y): n
- Do you want to allow SNMPv1/v2c read-write community access (default = y): n
- Do you want to allow SNMPv1/v2c read-only community access (default = y): y
- The community name to add read-only access for: cme
- The hostname or network address to accept this community name from [RETURN for all]: localhost
- The OID that this community should be restricted to [RETURN for no-restriction]: (RETURN)
- Do you want to configure where and if the agent will send traps? (default = y): n
- Do you want to configure the agent's ability to monitor various aspects of your system? (default = y): y
- Do you want to configure the agents ability to monitor processes? (default = y): y
- Name of the process you want to check on: ncftpd
- Maximum number of processes named 'ncftpd' that should be running [default = 0]: 100
- Minimum number of processes named 'ncftpd' that should be running [default = 0]: 1
- Do another proc line? (default = y): n
- Do you want to configure the agents ability to monitor disk space? (default = y): y
- Enter the mount point for the disk partion to be checked on: /var
- Enter the minimum amount of space that should be available on /var: %100
- Do another disk line? (default = y): y
- Enter the mount point for the disk partion to be checked on: /usr
- Enter the minimum amount of space that should be available on /usr: %100
- Do another disk line? (default = y): y
- Enter the mount point for the disk partion to be checked on: /home
- Enter the minimum amount of space that should be available on /home: %100
- Do another disk line? (default = y): n
- Do you want to configure the agents ability to monitor load average? (default = y): y
- Enter the maximum allowable value for the 1 minute load average: 12
- Enter the maximum allowable value for the 5 minute load average: 12
- Enter the maximum allowable value for the 15 minute load average: 12
- Do another load line? (default = y): n
- Do you want to configure the agents ability to monitor file sizes? (default = y): n
将会生成具有如下内容的snmpd.conf：
- syslocation "Bei Jing, China"
- syscontact master@xxx.com
- sysservices 77
- rocommunity cme localhost
- proc ncftpd 100 1
- disk /var %100
- disk /usr %100
- disk /home %100
- load 12 12 12
注意：请删除无用的说明部分！
之后执行下列命令：
cp snmpd.conf /usr/local/share/snmp/
vi /etc/rc.conf
向该文件添加如下内容：
之后执行：
roboot
重新启动计算机。
如启动时控制台出现
Starting snmpd
则证明安装完成
2. 安装和配置mrtg
使用ports安装mrtg，执行下列命令：
cd /usr/ports/net/mrtg
make install
mkdir -p /usr/local/www/data/mrtg/mrtgicons
cd work/mrtg-2.10.13/images
cp * /usr/local/www/data/mrtg/mrtgicons/
cd ../../..
make clean
mrtg软件安装完毕，执行下列命令：
cd /usr/local/etc/mrtg
cp mrtg.cfg.sample mrtg.cfg
vi mrtg.cfg
将mrtg.cfg文件内容修改如下：
- LoadMIBs: /usr/local/share/snmp/mibs/UCD-SNMP-MIB.txt
- WorkDir: /usr/local/www/data/mrtg
- Options[_]: growright,bits
- Refresh: 300

- #----------------------------------------------------------------------
执行下列命令生成mrtg首页
cd /usr/local/etc/mrtg/
indexmaker --title "我的网站" --columns 1 --output /usr/local/www/data/mrtg/index.html mrtg.cfg
不变更目录情况下，连续执行三次下列命令，知道不再报错为止：
mrtg mrtg.cfg
使用浏览器访问该位置，页面正常出现，则mrtg安装完毕 |
