以太网络最初是由全录公司 (Xerox PARC) 所建构出来的，而后透过 DEC, Intel 与 Xerox 合作将以太网络标 准化。 再经由 IEEE (Institute of Electrical and Electronic Engineers 注3) 这个国际著名的专 业组织利用一个 802 的项目制定出标准，之后有 19 家公司宣布支持 IEEE 所发布的 802.3 标准， 作动作，但如果程序与档案的 SELinux 类 型 (type) 不吻合时，那么该程序就无法读取该档案喔！ 此外，我们的 CentOS 也针对了某些常用的网络服务制 订了许多的档案使用规则 (rule)，如果这些规则没有启用， 那么即使权限、SELinux 类型都对了，该网络服务的 功能还是无法顺利的运作喔！ 根据这样的分析，我们可以知道，随时更新系统软件、限制联机端口以及透过启动 SELinux Dependencies 10.2. 7.2 网络自动升级软件 - 196 - 本文档使用 书栈(BookStack.CN) 构建 13. --> Running transaction check <==开始检查有没有相依属性的软件问题 14. ---> Package javacc.x86_64 0:4.1-0.5.el6 set to be updated 15. .

Web monitoring capabilities • Zabbix can follow a path of simulated mouse clicks on a web site and check for functionality and response time Extensive visualisation options • ability to create custom graphs 0 5.1 Defining multiple filters for low level discovery The filter section in low level discovery rule definition has been split out into a separate tab and, most importantly, allows to define several unlikely, but if the new value already exists in the database, the situation will be caught by a check on duplicates. Global macros will be processed in a special way by adding N_ after the dollar

Web monitoring capabilities • Zabbix can follow a path of simulated mouse clicks on a web site and check for functionality and response time Extensive visualisation options • ability to create custom graphs Internal events happen not only when items become unsupported, but also when a low-level discovery rule becomes unsupported or a trigger goes into an unknown state. The benefit of having internal events of SNMPv3 context name is now supported in item, item prototype, low-level discovery rule or network discovery rule configuration. User macros are resolved in this field. 5.16.2 SHA/AES protocol support

Web monitoring capabilities • Zabbix can follow a path of simulated mouse clicks on a web site and check for functionality and response time Extensive visualisation options • ability to create custom graphs events • ”Event type” conditions for internal events - Item in “normal” state, Low-level discovery rule in “normal” state, Trigger in “normal” state 11 For more details, see: • Actions • Recovery operations more user-friendly way. It is possible to view the details of these items, triggers and graphs. Check-boxes are enabled to apply mass operations to them. Thus it is possible to enable/disable/delete them

The possibility of using IP addresses parameter or external check would be treated as an unsupported item, and ignored for other item types by the Zabbix server. 5.3.2.4 External check parameter changes External check parameter handling was

Web monitoring capabilities • Zabbix can follow a path of simulated mouse clicks on a web site and check for functionality and response time Extensive visualization options • ability to create custom graphs unsupported, now it is possible to use a new preprocessing rule called ”Check for not supported value” to handle this situation. This preprocessing rule has standard Custom on fail options allowing to: • discard created: • Inherit (default) - the hosts will be created with the interface of a host the Discovery rule belongs to. If a host prototype is configured on the template level, then discovered hosts will inherit

Web monitoring capabilities • Zabbix can follow a path of simulated mouse clicks on a web site and check for functionality and response time Extensive visualisation options • ability to create custom graphs item Low-level discovery rule now can also be a dependent item, depending on a regular item. Low-level discovery rule cannot be dependent on another low-level discovery rule. To configure it as a dependent select Dependent item for ’Type’ and specify the master item in the ’Master item’ field in discovery rule configuration. Preprocessing and custom macros in low-level discovery Low-level discovery configuration

Web monitoring capabilities • Zabbix can follow a path of simulated mouse clicks on a web site and check for functionality and response time Extensive visualization options • ability to create custom graphs cache the result of calculated trend functions. Zabbix server, when processing trend functions, will check the trend cache for the cached result. In case of failure the server will read data from database ] internal item has been implemented to monitor the trend function cache effectiveness. New LLD rule filter condition operators In low-level discovery, it is now possible to set up filtering by the specified

Web monitoring capabilities • Zabbix can follow a path of simulated mouse clicks on a web site and check for functionality and response time Extensive visualization options • ability to create custom graphs the new version it is possible to test the item (template item, item prototype, low-level discovery rule) from the user interface even before saving and, if configured correctly, get a real value in return also: • Testing an item • Testing preprocessing steps Execute now In a related development the Check now option has been renamed to Execute now, to avoid confusing it with the item testing functionality
