牛圈: MRTG配置笔记

mrtg官方网站：http://oss.oetiker.ch/mrtg/index.en.html

在http://www.sunfreeware.com/下载for solaris9 sprac的版本，直接pkgadd进
行安装。
mrtg同时需要libgcc、perl、apache、net-snmp等软件支持。

【mrtg安装配置步骤】
1、安装mrtg
pkgadd -d mrtg-2.16.2-sol9-sparc-local

2、建立mrtg工作目录
mkdir /export/home/gdau/mrtg_test

3、配置apache的httpd.conf
vi /etc/apache/httpd.conf，增加：
-------------------------------------------------------------------
Alias /cmnet/ "/export/home/gdau/mrtg_test/"
<Directory "/export/home/gdau/mrtg">
Options Indexes FollowSymlinks MultiViews
AllowOverride None
Order allow,deny
Allow from all
</Directory>
-------------------------------------------------------------------

4、启动apache
/etc/init.d/apache start、stop、restart

5、生成mrtg.cfg文件
perl /usr/local/mrtg-2/bin/cfgmaker --global "WorkDir:
/export/home/gdau/mrtg_test/221.130.208.50__GXNN-BC-SXNET-RT01-NE80E"
--global "options[_]: growright,bits" --ifdesc=alias
--snmp-options=:::::2 ChinaMobile_Manager_Read@221.130.208.50 --output
/export/home/gdau/mrtg_test/221.130.208.50__GXNN-BC-SXNET-RT01-NE80E/mrtg.cfg

6、进行采集
perl /usr/local/mrtg-2/bin/mrtg
/export/home/gdau/mrtg_test/221.130.208.50__GXNN-BC-SXNET-RT01-NE80E/mrtg.cfg

首次运行会报错，运行三次以上便可以消除错误。

7、生成网页首页文件
perl /usr/local/mrtg-2/bin/indexmaker
--output=/export/home/gdau/mrtg_test/221.130.208.50__GXNN-BC-SXNET-RT01-NE80E/index.html
--title=CMNET
/export/home/gdau/mrtg_test/221.130.208.50__GXNN-BC-SXNET-RT01-NE80E/mrtg.cfg

8、将采集命令放置crontab，最小粒度为5分钟运行。

以下为：自动生成mrtg.cfg配置文件和自动采集shell脚本
-------------------------------------------------------------------
cmnet_flow_mrtg_cfg.sh
-------------------------------------------------------------------

【存在问题】
1、mrtg对大流量端口不支持。mrtg默认针对ifTable进行采集，采集的ifIn和
ifOut都为32位。但是针对高速端口，流速很大，32位的Counter很容易溢出。必须
要配置snmp V2版本支持才行。原理是使用ifXTable中的ifHCIn和ifHCOut来采集。
在生成mrtg.cfg文件时，增加：--snmp-options=:::::2选项
由于mrtg（版本：2.16.2）本身存在bug，需要修改cfgmaker脚本的907行。将：
if(not $speed or $counter eq "" or $counter =~ /\D/ or
$SNMP_Session::errmsg or $Net_SNMP_util::ErrorMessage){
修改为：
if(not $speed or $counter eq "" or $counter !~ /\d/ or
$SNMP_Session::errmsg or $Net_SNMP_util::ErrorMessage){
目的是禁止在mrtg.cfg文件中生成noHC：yes的选项。

2、对华为的设备，不支持采集ifAlias。
修改cfgmaker文件，修改：173行。将：
if ($routers->{$router}{deviceinfo}{Vendor} eq 'cisco' &&
$routers->{$router}{deviceinfo}{sysDescr} =~ m/Version\s+(\d+\.\d+)/) {
push @Variables, ($1 > 11.0 or $1 < 10.0 ) ? "ifAlias" : "CiscolocIfDescr";
if ($1 > 11.2) {push @Variables, "vmVlan";};
if ($1 > 11.3) {push @Variables, "vlanTrunkPortDynamicStatus";};
} elsif ( $routers->{$router}{deviceinfo}{Vendor} =~
/(?:hp|juniper|foundry|dellLan|force10|3com|extremenetworks)/) {
push @Variables, "ifAlias";
}
修改为：
if ($routers->{$router}{deviceinfo}{Vendor} eq 'cisco' &&
$routers->{$router}{deviceinfo}{sysDescr} =~ m/Version\s+(\d+\.\d+)/) {
push @Variables, ($1 > 11.0 or $1 < 10.0 ) ? "ifAlias" : "CiscolocIfDescr";
if ($1 > 11.2) {push @Variables, "vmVlan";};
if ($1 > 11.3) {push @Variables, "vlanTrunkPortDynamicStatus";};
} elsif ( $routers->{$router}{deviceinfo}{Vendor} =~
/(?:hp|juniper|foundry|dellLan|force10|3com|extremenetworks)/) {
push @Variables, "ifAlias";
} else {
push @Variables, "ifAlias";
}
