server 转发到 Kafka broker。 异步 pollers 新的 poller 进程能够同时执行多个检查，它分出了以下 poller 类型：- agent poller - http agent poller - snmp poller ( 支持 walk[OID] 和 get[OID] 监控项) 这些 poller 进程是异步的 - 它们可以在不等响应的情况下启动新的检查，并可以配置最多 以配置最多 1000 个并发检查。 异步 poller 的设计是为了提高效率，与同步轮询器相比，同步 poller 在同一时间只能执行一个检查，并且大部分时间都花费在等待响应 上。 server/proxy 配置文件中新增了 pollers 参数，你可以通过修改StartAgentPollers 参数值来启动指定数量的 agent pollers。可以通过分别 修改StartHTTPAgentPollers agent pollers 和 SNMP pollers。 异步 pollers (agent, HTTP agent and SNMP) 的最大并发数是由MaxConcurrentChecksPerPoller 定义的。 要注意升级后，所有的 agent、HTTP agent and SNMP walk[OID] poller 检查将都会切换为异步 pollers。 作为开发的一部分，持久连接 cURL

Zabbix agent 安装为 Windows 服务： 39 C:> c:\zabbix\zabbix_agentd.exe -c c:\zabbix\zabbix_agentd.conf -i 现在您可以像任何其他 Windows 服务一样配置 “Zabbix agent” 服务。 有关在 Windows 上安装和运行 Zabbix agent 的详细信息，请查阅于此。 其它 agent 运行时机制的控制。 仅 Windows agent -m --multiple-agents 使用多个 Agent 实例（使用 -i、-d、-s、-x）。为了区分实例的服务名 称，每项服务名都会包涵来自配置文件里的 Hostname 值。 ** 仅 Windows agent （功能）** -i --install 以服务的形式安装 Zabbix Windows agent。 -d --uninstall 卸载 zabbix_agentd -t ”mysql.ping” -c /etc/zabbix/zabbix_agentd.conf shell> zabbix_agentd.exe -i shell> zabbix_agentd.exe -i -m -c zabbix_agentd.conf 运行时控制 使用运行时控制选项，您可以更改 agent 进程的日志级别。 选项 描述 目标 log_level

trigger-based event correlation. Expansion of inventory macros in event tags allows to correlate events (i.e. problems and their resolution), for example, by data- center location, responsible system administrator the master item for dependent items that get their data from. A selected set of internal metrics (i.e. not all) is returned by either of these two items. There are also another two new items allowing the ’skip’ option, e. g. vmware.eventlog[,skip] now behaves differently after being recreated (i.e. previous item removed, new one created with a different internal ID) - now the internal events cache

problems It is now possible to configure ways of displaying operational data for current problems, i.e. the latest item values as opposed to the item values at the time of the problem. Operational data macros can be used to create item prototypes using the vfs.dev.read[] and vfs.dev.write[] agent items, i.e. vfs.dev.read[{#DEVNAME},sps]. See also: Discovery of block devices.

These fields are context aware: 10 • The values are pre-filled when possible, i.e. for items requiring an agent, by taking the information from the selected agent interface of the with the --with-timestamps option, e.g.: zabbix_sender -z 127.0.0.1 --with-timestamps --with-ns -i values.txt This option specifies that each line of the input file contains the following, whitespace-delimited: passwords instead of MD5. The change to the stronger cryptography after the upgrade is automatic, i.e. no effort on the user side is required. Note that passwords longer than 72 characters will be truncated
