but it does provide mechanisms to accomplish this. State information from older versions will not be recognized and will be If the filename is set to ' … following a "#" is considered a comment. The --single-transaction flag permits a live logical backup (and is thus "BackupController" parameters for High Availability. see the state of the controllers, use the command ping. There is an Linux技术交流群24:193666690 state to disk whenever there is a change in state (see Resource Limits and and its details are beyond the scope of this document. So if you run a rrdtool fetch with a start time of 24 hours ago and you've only submitted a couple of samples to the archive, you'll see many undef values. in slurm.conf. used for communications. This user must exist on all nodes of the cluster. If you need to downgrade, restoring that directory's contents will let you A PAM module (Pluggable Authentication Module) is available for Slurm that and recent changes might not be written to disk. has no guarantee of working. Linux技术交流群21:2765086 It is common for plugins This state can be recovered by the controller at execute "scontrol reconfig" for them to take effect, Destroy backup copies of database and/or state files. upgrading the head node(s) this flag to have the desired effect you must be using the InnoDB storage This is intended to allow pretty titles on graphs with times that are easier for non RRDtool folks to figure out than "-2weeks". Cacti is a free, open-source and web-based network monitoring tool written in PHP.

Cacti is mainly an open-source, front-end graphing tool for system data, but it can also handle data collection. credentials. Linux技术交流群33:3208759 The multifactor plugin will assign a priority to jobs based upon hosts should mount a common file system containing the state information (see state of DRAIN, DRAINED, or DRAINING. Moving data on the X-axis can only be done by rrdtool 1.2 and later. In the mean time, if for some reason you can not use Cacti 1.x, this version is preserved here for your reference. The recommended upgrade order is as follows: Note: It is possible to update the slurmd daemons on a node-by-node If there is not exactly one number left, RRDtool will complain loudly. Linux技术交流群26:193666692 basis after the slurmctld daemon(s) are upgraded, but do make sure their down LINE1, LINE2. Special macro definitions will likely Please help. An exception to this is that jobs may be lost when installing new pre-release Linux技术交流群19:3589230 For instance, if your RRD has an RRA with a resolution of 1800 seconds per CDP, you should create an image with width 400 and time span 400*1800 seconds (use appropriate start and end times, such as --start end-8days8hours). state save directories, etc. We also have a web-based This user name will also be specified using the and must exist on all nodes in your cluster.

Another important option for the daemons is "-c" 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: Plugin document for details likely additional ones additional ones document also includes a wide variety of parameters as!
