cacti
使用persona for cacti插件监控mysql
需要mysql调优，安装了一个cacti监控插件 Percona Monitoring Plugins ，
官方地址：http://www.percona.com/software/percona-monitoring-plugins/
1 下载 percona-monitoring-plugins-1.0.0.tar.gz
2 上传 ss_get_mysql_stats.php 到cacti的scripts目录/usr/share/cacti/site/scripts
3 进入cacti的web页面import 数据模版cacti_host_template_percona_mysql_server_ht_0.8.6i-sver1.0.0.xml
4 设置ss_get_mysql_stats.php里的mysql账号链接
5 Percona Monitoring Plugins参考文档：http://form.percona.com/rs/percona/images/Percona_Monitoring_Plugins_100_Operations_Manual.pdf
cacti的rrdtool画不出图来的问题
1 习惯性的把rrd的文件rm -rf *掉了，发现cron过了好多次都没画出图来
2 检查权限，权限ok的,cron的执行用户和/var/www/cacti/rra目录的拥有者是同一个用户
bear@njava:/var/www/cacti/rra$ sudo vi /etc/crontab # /etc/crontab: system-wide crontab # Unlike any other crontab you don't have to run the `crontab' # command to install the new version when you edit this file # and files in /etc/cron.d. These files also have username fields, # that none of the other crontabs do. SHELL=/bin/sh PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin # m h dom mon dow user command 17 * * * * root cd / && run-parts --report /etc/cron.hourly 25 6 * * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily ) 47 6 * * 7 root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly ) 52 6 1 * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly ) */5 * * * * www-data php /var/www/cacti/poller.php > /dev/null 2>&1
3 把Poller Type由spine改成cmd.php，奇迹发生了，图被画出来了，之后再改回spine,运转正常
cacti通过snmp监控ubuntu9.10网卡流量遇到的问题
折腾无线，snmp总是链接不上，debug报如下错误；
+ Running data query [1]. + Found type = '3' [snmp query]. + Found data query XML file at '/var/www/cacti/resource/snmp_queries/interface.xml' + XML file parsed ok. + Executing SNMP walk for list of indexes @ '.1.3.6.1.2.1.2.2.1.1' + No SNMP data returned + Found data query XML file at '/var/www/cacti/resource/snmp_queries/interface.xml' + Found data query XML file at '/var/www/cacti/resource/snmp_queries/interface.xml' + Found data query XML file at '/var/www/cacti/resource/snmp_queries/interface.xml'
谷歌百度，终于找到解决办法，记录之。。。

在ubuntu9.10下用cacti监控nginx运行
Cacti 在英文中的意思是仙人掌的意思，Cacti是一套基于PHP,MySQL,SNMP及RRDTool开发的网络流量监测图形分析工具。它通过snmpget来获取数据，使用 RRDtool绘画图形，而且你完全可以不需要了解RRDtool复杂的参数。它提供了非常强大的数据和用户管理功能，可以指定每一个用户能查看树状结 构、host以及任何一张图，还可以与LDAP结合进行用户验证，同时也能自己增加模板，功能非常强大完善。http://www.cacti.net/
1 安装cacti
bear@njava:/$ sudo apt-get install cacti-cactid
2 下载cacti-nginx脚本
bear@njava:/$ wget http://forums.cacti.net/download.php?id=12676 bear@njava:/$ tar -xzvf cacti-nginx.tar.gz bear@njava:/$ sudo cp cacti-nginx/get_nginx_socket_status.pl /usr/share/cacti/site/scripts bear@njava:/$ sudo cp cacti-nginx/get_nginx_clients_status.pl /usr/share/cacti/site/scripts bear@njava:/$ sudo chmod 755 /usr/share/cacti/site/scripts/get_nginx*
3 检查脚本
bear@njava:/$ /usr/share/cacti/site/scripts/get_nginx_socket_status.pl http://www.njava.com/nginx_status
4 配置cacti的nginx虚拟主机
bear@njava:$ sudo vi /etc/nginx/sites-available/cacti
server {
listen 80;
server_name cacti.njava.com;
access_log /var/log/nginx/cacti.access.log;
location / {
root /usr/share/cacti/site;
index index.html index.htm index.php;
}
location ~ \.php$ {
fastcgi_pass unix:/tmp/php-cgi.njava.sock;
fastcgi_index index.php;
set $path_info "/";
set $real_script_name $fastcgi_script_name;
if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
set $real_script_name $1;
set $path_info $2;
}
fastcgi_param SCRIPT_FILENAME /usr/share/cacti/site/$real_script_name;
fastcgi_param script_name $real_script_name;
fastcgi_param path_info $path_info;
include /etc/nginx/fastcgi_params;
}
}
bear@njava:$ sudo ln -s /etc/nginx/sites-available/cacti /etc/nginx/sites-enable/cacti
bear@njava:$ sudo /etc/init.d/nginx reload
5 从cacti的UI上传cacti模板
cacti_graph_template_nginx_clients_stat.xml cacti_graph_template_nginx_sockets_stat.xml
