终于到了，这个 pose 潮人伐

说说近期的情况和生活吧。

1. PS3 神机入手，当时只在 twitter 上留言 CX 一哈，特此补发（2009.10.03 入手）

2. 远在哈尔滨的小姨子和妹夫 11 月份来上海看望了我们，并带来许多干肠，怨念啊

3. 随公司去了一次东方绿洲和朱家角，感觉良好

4. 好友终于买车了，这样每个周末的 羽毛球+FB+三国杀 队伍扩充至 6 人（偶在乡下比较远）

5. 孝敬了 哈尼 大人一台 ipod nano5（背面刻有她的 twitter id 哦 ）

6. 移动 IDC 杯具，导致整整业务中断了 48 小时，以后无线业务会越来越难做

7. 参加了同学婚礼，目前算下来朋友中该摆酒的都摆了，偶们自己的还是遥遥无期，真有点对不起哈尼

1. install package

yum -y install httpd
yum -y install php
yum -y install php-mysql
yum -y install php-snmp
yum -y install mysql-server
yum -y install perl
yum -y install net-snmp-utils
yum -y install libpng
yum -y install freetype
yum -y install libart_lgpl

2. set chkconfig

chkconfig httpd on
chkconfig mysqld on

3.download rrdtool http://oss.oetiker.ch/rrdtool/download.var

wget http://dag.wieers.com/rpm/packages/rrdtool/perl-rrdtool-1.2.23-1.el5.rf.i386.rpm
wget http://dag.wieers.com/rpm/packages/rrdtool/rrdtool-1.2.23-1.el5.rf.i386.rpm

4.install rddtool

rpm -ivh perl-rrdtool-1.2.23-1.el5.rf.i386.rpm rrdtool-1.2.23-1.el5.rf.i386.rpm

5. change mysql charset
vi /etc/my.cnf

[mysqld]
collation-server = utf8_general_ci
default-collation = utf8_general_ci
character-set-server = utf8
default-character-set = utf8

6. download cacti

wget http://www.cacti.net/downloads/cacti-0.8.7d.tar.gz
tar zxvf cacti-0.8.7d.tar.gz

7. download cacti-plugin-0.8.7d-PA-v2.4.zip from cactiuser & extract it
2 method of install:

1) cd /path/cacti-0.8.7d && patch -p1 -N --dry-run < /path/to/cacti-plugin-0.8.7d-PA-v2.4.diff
2) cd /path/cacti-0.8.7d && cp -R /path/to/files-0.8.7d/* ./

注： 第一种方式在我这里报错了，官方论坛上也有提及，如果你也有遇到可以直接用第二种方式更新

8. imp cacti db

mysqladmin create cacti
mysql -u root -p cacti < /path/to/cacti.sql
mysql -u root -p cacti < /path/to/pa.sql
mysql> create user cacti@’localhost’;
mysql> create user cacti@’127.0.0.1′;
mysql> grant all privileges on cacti.* to cacti@’localhost’;
mysql> grant all privileges on cacti.* to cacti@’127.0.01′;
mysql> set password for cacti@’localhost’ = password(’cactipasswd’);
mysql> set password for cacti@’127.0.0.1′ = password(’cactipasswd’);

9. ensure the db-section at global.php is correct

vi /opt/www/html/cacti/include/global.php #-->check this section: /* Default database settings*/

10. set crontab
crontab -u cacti -e

*/5 * * * * /usr/bin/php /opt/www/html/cacti/poller.php > /dev/null 2>&1

11. install threshold

wget http://cactiusers.org/downloads/settings.tar.gz
wget http://cactiusers.org/downloads/thold.tar.gz
wget http://cactiusers.org/downloads/monitor.tar.gz

12. exract

tar zxvf settings.tar.gz
tar zxvf thold.tar.gz
tar zxvf monitor.tar.gz

13. place plug-in files into appropriate directory

mv settings /opt/www/html/cacti/plugins/
mv thold /opt/www/html/cacti/plugins/
mv monitor /opt/www/html/cacti/plugins/

14. update mysql db

mysql -u root -p cacti < thold.sql
mysql -u root -p cacti < monitor.sql

15. activate plug-ins now:
vi /opt/www/html/cacti/include/global.php

$plugins = array();
$plugins[] = 'settings';
$plugins[] = 'thold';
$plugins[] = 'monitor';

16. After installation, the 1st thing u need do is edit admin account, otherwise the “plug-in management” & “ThreshHold Templates” will not be added into console tab
Console -> User Management -> admin

Now go to:
Console -> Plugin Management
At “Thresholds”, click “Install” & “Enable”

17. Use Tholds
17.1 mail settings
Go to console -> Settings select the “Mail/DNS” tab
Go to console -> Settings select the “Alerting/Thold” tab
enable “Dead Hosts Notifications”
Dead Host Notifications Email: enter the web-admin mail account
From Email Address: cacti alert mail accout
Save the configuration.
Then we will receive alter-mail when a host goes down or up:

17.2 create Threshhold Templates
Go to Console -> Threshhold Templates
Create you need

17.3 Apply the Threshhold Templaes

Then Go to Console -> devices
Click the device you want to apply the Threshhold Template
And then click “Create Graphs for this Host”

Create Graphs for this Host -> Auto-create thresholds

17.4 some threshold examples

Create disk usage Thold template
When (used_space/total_space%) > 90%, cacti will send alert mail
4.1.1 Add “VALUE_OF_HDD_TOTAL” at global _arrays.php

vi /opt/www/html/cacti/include/global _arrays.php
add VALUE_OF_HDD_TOTAL

find

$custom_data_source_types = array(

add

"VALUE_OF_HDD_TOTAL" => "Value of hdd_total data source",

add a new CDEF
Now go to Console -> Graph Management -> CDEFs click “Add” to add a new CDEF
Add new CDEF named like “Used Disk Space Percent”, at this CDEF, add 5 items:

Item #1 Special Data Source: CURRENT_DATA_SOURCE
Item #2 Custom String: 100
Item #3 Operator: *
Item #4 Special Data Source: VALUE_OF_HDD_TOTAL
Item #5 Operator: /

create new Threshold Templates
Go to Console -> Threshold Templates -> click Add
For linux host, we choose “ucd/net – CPU Usage - user” template;
for windows host, we choose “Host MIB - Hard Drive Space” template
this depends on what templates we used in device graphic:

Data Field: hdd_used
Enabled: yes
Threshold Type: High / Low
High Threshold: 90
Low Threshold: 0
Data Type: CDEF

Threshold CDEF: Used Disk Space Percent (the CDEF Name we just created)
Alert E-Mail: the email-address that alert message will send to
