Zabbix has a beautiful traffic summary chart, but if you need to look at network traffic more intuitively overall, you need to add port traffic information to the topology chart, and the traffic can be labeled directly on the inter-device connection. The first thing you need to link to two devices on the topology map, as shown in the figure: Fill in the flow label: Global: "Host Name: net.if.i[ifHCInOctets.接口序号]n.last (0);; Host name: net.if.ou[ifHCOutOctets.接口序号]t.last (0)) Chinese location needs to be replaced according to the actual situation, the need to pay attention to the format, in and out is relative, according to the actual determination.The host name corresponds to the added host name, and the port serial number can be found in the monitoring item in the configuration of the added host, such as net.if.in[ifHCInOctets.33] Here's an example: Save the update, exit edit mode, and be visible when the topology map is reopened, and this is done.

Zabbix具有很美观的流量汇总图表，但是如果需要在整体上更直观地查看网络流量就需要在拓扑图上添加端口流量信息，流量可以直接标注在设备间连线上。 首先需要在拓扑图上链接上两台设备，如图： 填入流量标签： Global: ↓{主机名称:net.if.in[ifHCInOctets.接口序号].last(0)}; ↑{主机名称:net.if.out[ifHCOutOctets.接口序号].last(0)} 中文所处位置需根据实际情况自行替换，｛｝内的需要注意格式，in和out是相对的，根据实际确定。主机名要和已添加的主机名称对应，端口序号可以在所添加的主机的配置中的监控项中找到，如 net.if.in[ifHCInOctets.33] 示例如下： 保存更新，退出编辑模式，重新打开拓扑图后可见，就此完成。

用户设置为中文后，Zabbix图形的中文文字会显示小方框，由于原字体不支持中文， 我们需要替换为支持的字体。 一、上传字体到目录 上传你挑选的字体到 /usr/share/zabbix/fonts/ ，ttf格式，不需要改名，我这里用的等线字体。 二、修改PHP配置指定新字体 修改/usr/share/zabbix/include/中的defines.inc.php文件 在约第65行，找到define('ZBX_GRAPH_FONT_NAME', '替换新字体的名字'); 保存后即生效，效果如图：

Zabbix is an enterprise-class open source solution based on a WEB interface that provides distributed system monitoring and network monitoring capabilities.Zabbix monitors various network parameters, secures the safe operation of the server system, and provides a robust notification mechanism for system operators to quickly locate/resolve problems.Zabbix consists of 2 parts, Zabbix server and optional component Zabbix agent.Zabbix server can provide monitoring of remote server/network status, data collection and other functions through SNMP, Zabbix agent, ping, port monitoring, etc.It can run on Linux, Solaris, HP-UX, AIX, Free BSD, Open BSD, OS X and more. Zabbix solves the problem of cacti without warning, also solves the shortcomings that nagios can not configure through the web, and also supports distributed deployment, which makes it quickly popular, zabbix has become the most popular operation monitoring platform for small and medium-sized enterprises. Of course, Zabbix also has shortcomings, it consumes more resources, if the monitoring of the host is very many, there may be monitoring timeout, alarm time-out and other phenomena, but there are many solutions, such as improve hardware performance, change zabbix monitoring mode. Zabbix's official document details the installation requirements below: https://www.zabbix.com/documentation/4.0/zh/manual/installation Here's an example of CentOS 7 One, add Zabbix software repository Then yum makecache Second, install the Zabbix deployment package yum install zabbix-server-mysql zabbix-web-mysql mariadb-server Zabbix components, MariaDB, Apache httpd, and PHP 5.4 are automatically installed. Third, create a database, import the initial table data 1. Start database: systemctl start mariadb 2. Login database: mysql -uroot -p return, password empty direct return 3. New zabbix blank database: create database zabbix character…

Zabbix是一个基于WEB界面的提供分布式系统监视以及网络监视功能的企业级的开源解决方案。Zabbix能监视各种网络参数，保证服务器系统的安全运营，并提供强大的通知机制以让系统运维人员快速定位/解决存在的各种问题。Zabbix由2部分构成，Zabbix server与可选组件Zabbix agent。Zabbix server可以通过SNMP，Zabbix agent，ping，端口监视等方法提供对远程服务器/网络状态的监视，数据收集等功能。它可以运行在Linux, Solaris, HP-UX, AIX, Free BSD, Open BSD, OS X等平台上。 Zabbix解决了cacti没有告警的不足，也解决了nagios不能通过web配置的缺点，同时还支持分布式部署，这使得它迅速流行起来，zabbix也成为目前中小企业监控最流行的运维监控平台。 当然，Zabbix也有不足之处，它消耗的资源比较多，如果监控的主机非常多时，可能会出现监控超时、告警超时等现象，不过也有很多解决办法，比如提高硬件性能、改变zabbix监控模式等。 Zabbix的官方文档如下，详细描述了安装要求：https://www.zabbix.com/documentation/4.0/zh/manual/installation 以下以CentOS7为例 一、 添加 Zabbix 软件仓库 随后 yum makecache 二、安装Zabbix部署包 yum install zabbix-server-mysql zabbix-web-mysql mariadb-server 会自动安装Zabbix组件、MariaDB、Apache httpd和PHP5.4。 三、创建数据库，导入初始表数据 1.启动数据库：systemctl start mariadb 2.登入数据库：mysql -uroot -p回车后，密码为空直接回车 3.新建zabbix空白数据库：create database zabbix character set utf8 collate utf8_bin; 4.设置数据库权限：grant all privileges on zabbix.* to [email protected] identified by 'zabbix'; 5.检查数据库后退出数据库 6.导入zabbix初始数据库：zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix 7.重新进入数据库查看是否导入成功： 四、连通zabbix和数据库 修改配置文件，填入数据库实际验证信息# vi /etc/zabbix/zabbix_server.confDBHost=localhostDBName=zabbixDBUser=zabbixDBPassword=<password> 五、启动zabbix服务端 systemctl start zabbix-server 此时可能会报错，输入tail -f /var/log/zabbix/zabbix_server.log 查看报错信息，输出如下： 推荐直接关闭SELinux，关闭防火墙和SELinux之后，服务正常启动。 六、修改前端Httpd配置 修改/etc/httpd/conf.d/zabbix.conf 中的# php_value date.timezone Europe/Riga，如图 启动Apache Httpd：systemctl start httpd 七、Web界面配置 进入网址：<服务器IP>/zabbix 跟随页面提示配置好即可登录，默认帐号密码是Admin zabbix 完成：

The occ command is the command line interface of DownCloud/Nextcloud.You can use occ to perform many common server operations, such as installing and upgrading downCloud/Nextcloud, managing users, encryption, passwords, LDAP settings, and more. In Nextcloud's background security and settings warning, it appears: "Some columns in the database are missing due to long-format conversions.Because it takes some time for a largedata table to change the column type, the program does not automatically change it.You can manually execute the "occ db:convert-filecache-bigint" command manually from the command line to apply pending changes.This needs to be done when the entire instance becomes offline. You can shut down the web service first, or shut down the site. ROOT logs into SSH and enters the root of the website file.Input: sudo -u www (your own web user) php occ db:convert-filecache-bigint The feedback is as shown: After entering y return, the personal small net disk can be completed in a matter of seconds.Then go backstage to refresh the alarm and disappear.

occ命令是ownCloud/Nextcloud的命令行界面。您可以使用occ执行许多常见的服务器操作，例如安装和升级ownCloud/Nextcloud，管理用户，加密，密码，LDAP设置等。 在Nextcloud的后台安全及设置警告中会出现："数据库中的一些列由于进行长整型转换而缺失。由于在较大的数据表重改变列类型会耗费一些时间，因此程序没有自动对其更改。您可以通过命令行手动执行 \"occ db:convert-filecache-bigint\" 命令以应用挂起的更改。该操作需要当整个实例变为离线状态后执行。 这个时候可以先关闭web服务，或者关闭该站点。 ROOT登陆到SSH，进入网站文件根目录。输入： sudo -u www(你自己的web用户) php occ db:convert-filecache-bigint 反馈如图： 输入y回车后，个人小网盘大概几秒钟就能完成。然后去后台刷新该告警就会消失。
