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。Cacti 的发展是基于让 RRDTool 使用者更方便使用该软件，除了基本的 Snmp 流量跟系统资讯监控外，Cacti 也可外挂 Scripts 及加上 Templates 来作出各式各样的监控图。, cacti是用php语言实现的一个软件，它的主要功能是用snmp服务获取数据，然后用rrdtool储存和更新数据，当用户需要查看数据的时候用rrdtool生成图表呈现给用户。因此，snmp和rrdtool是cacti的关键。Snmp关系着数据的收集，rrdtool关系着数据存储和图表的生成。, Mysql配合PHP程序存储一些变量数据并对变量数据进行调用，如：主机名、主机ip、snmp团体名、端口号、模板信息等变量。, snmp抓到数据不是存储在mysql中，而是存在rrdtool生成的rrd文件中（在cacti根目录的rra文件夹下）。rrdtool对数据的更新和存储就是对rrd文件的处理，rrd文件是大小固定的档案文件（Round Robin Archive），它能够存储的数据笔数在创建时就已经定义。关于RRDTool的知识请参阅RRDTool教学。, snmp(Simple Network Management Protocal, 简单网络管理协议)在架构体系的监控子系统中将扮演重要角色。大体上，其基本原理是，在每一个被监控的主机或节点上 (如交换机)都运行了一个 agent，用来收集这个节点的所有相关的信息，同时监听 snmp 的 port，也就是 UDP 161，并从这个端口接收来自监控主机的指令(查询和设置)。, 如果安装 net-snmp，被监控主机需要安装 net-snmp(包含了 snmpd 这个 agent)，而监控端需要安装 net-snmp-utils，若接受被监控端通过trap-communicate发来的信息的话，则需要安装net-snmp，并启用trap服务。如果自行编译，需要 beecrypt(libbeecrypt)和 elf(libraryelf)的库。, RRDtool是指Round Robin Database 工具（环状数据库）。Round robin是一种处理定量数据、以及当前元素指针的技术。想象一个周边标有点的圆环－－这些点就是时间存储的位置。从圆心画一条到圆周的某个点的箭头－－这就是指针。就像我们在一个圆环上一样，没有起点和终点，你可以一直往下走下去。过来一段时间，所有可用的位置都会被用过，该循环过程会自动重用原来的位置。这样，数据集不会增大，并且不需要维护。RRDtool处理RRD数据库。它用向RRD数据库存储数据、从RRD数据库中提取数据。, Cacti整个系统的架构是这样的：基于SNMP协议，被监控端是服务器，或一些网络设备，网络管理工作站，采用Linux(或Freebsd)操作系统，并且安装Net-SNMP工具，使用RRDTOOL采集数据，存储数据，并用Cacti调用rrdtool显示出来。, 以下使用CentOS release 6.7 (Final)进行安装，将cacti根目录放置在/web/vhosts，并配置web服务器使用http://cacti.feiyu.com/进行访问，首先在主监控机上安装LAMP的web环境，此处直接使用yum进行安装。, 然后开始在浏览器中访问cacti，指定 rrdtool、 php、 snmp 工具的 Binary 文件路径，确保所有的路径都是显示”FOUND”，没有 “NOT FOUND”的，点击 Finish 完成安装。默认账号和密码都是admin，首次登陆首先需要修改密码。, Data Input Methods -> Input Fields(添加所需要的参数) -> Output Fields(输出字段，名字要与脚本所定义的名字保持一致) -> Data Templates（定义数据模板）-> Data Sources（定义数据源）-> Graph Templates（定义图像模板并添加图像） Graph Template Items -> 并为每一个图像添加GPRINT（需要为每个数据源添加Current，Average，Max）-> Graph Management （添加图片）-> Export Templates（导出模板）, （1）在Data Input Methods中添加脚本，并需要在Input Fields中添加用户需要传的参数，http://cacti.feiyu.com/，进入cacti图形窗口，点击Data Input Methods–>add，如下所示：, （2）然后在 Iutput Fields定义输入字段2个，与脚本中的输入保持一致：, （4）数据收集后需要保存在RRD文件中,然后创建RRD文件，在Data Templates中添加数据模板：, （9）然后再添加对图片的说明（图片下面的彩色方块）：Console -> Graph Templates -> (Edit) -> Graph Template Items，将Current，Average，Max都添加上去：, 本文地址：https://www.linuxprobe.com/cacti-install-use.html编辑：陶武杰，审核员：苏西云, 本文原创地址：https://www.linuxprobe.com/cacti-install-use.html编辑：public，审核员：暂无, 转载必需保留本文链接: execute "scontrol reconfig" for them to take effect, Shutdown the slurmd daemons on the compute nodes, Copy the contents of the configured StateSaveLocation directory (in case Linux技术交流群28：193666694 RRDtool(ラウンドロビンデータベースツール)とは、時系列データ用の高性能な「データロギング」および「グラフ作成」ツールです。 詳細および申し込みはこちら 2021/01/21 LINEミニアプリを活用した顧客コミュニケーションDX ～LINE・AWS上でのアプリ開発事例から学ぶ～ If you need to downgrade, restoring that directory's contents will let you For this reason, creating backup copies of state files (as described below) STACK them if you like. can prevent a user from accessing a node which he has not been allocated, 默认为前1天至此刻的时间跨度，这也是具有最好解析度的时间跨度。start和end接受多种时间格式为其值。默认情况下， rrdtool graph会计算在指定的时间跨度内1个像素所对应的时间长度，并以之为解析度从RRA中获取数据； if the major release number changes, which typically happens about every nine manages user jobs, it must execute as the user root.
