我正在使用 zabbix 2.4.7 和 Low Level Discovery，它解析命令的输出varnishadm backend.list并发送给 zabbix，例如：
[root@host4 ~]# varnishadm backend.list | column -t | grep apetit -C 2
be_bucket(127.0.0.1,,2676) 1 probe Healthy (no probe)
be_apetitar(127.0.0.1,,2677) 3 probe Healthy (no probe)
be_adeliveria(127.0.0.1,,2675) 1 probe Healthy (no probe)
一切都运行良好（项目正在绘制，图形正在运行，触发器也是如此），除了一个细节：
在主机上，我可以看到很多“主动检查“varnish.backends[be_xxxx,conn]”不受支持”。在服务器日志中，我可以看到很多，例如：
7603:20160304:163453.953 item "host4:varnish.backends[be_apetitar,conn]" became supported
7603:20160304:163544.366 item "host4:varnish.backends[be_apetitar,conn]" became not supported: Unsupported item key.

7610:20160304:163942.025 item "host4:varnish.backends[be_apetitar,conn]" became not supported: Unsupported item key.

答案1
解决了！
- “物品原型”从“代理（活跃）”更改为“Zabbix Trapper”
- “项目”varnish_backends_collect 更改为“Zabbix 代理（活动）”
结束配置：
- 发现 = varnish_backends = Zabbix 代理 = 600 秒
- 项目原型 = varnish.backends[{#BACKEND},conn] = Zabbix trapper
- 项目 = varnish_backends_collect = Zabbix 代理（活跃）= 120 秒
最后一条拍打日志是昨天的：

答案2
我遇到过类似的问题，但都是 SNMP、NetApps 和其他设备的问题。根本不涉及 Zabbix 代理或诱捕器。
使用 SNMPv1 测试对 SNMPv2 设备（如 NetApp 或 NetBot）进行测试将导致测试以完全相同的方式发生抖动。将 Zabbix 中的抖动测试项目更新为 SNMPv2 将解决该问题。
