一.zabbix 主動與被動監控模式
被動模式：
無論是模式還是被動模式，都是站在zabbix agent角度來說的工作模式，比如被動模式，是說zabbix agent被動的接受zabbix server周期性發送過來的數據收集指令，在被動模式之下，zabbix server會根據主機關聯的模板中的監控項和數據采集間隔時間，周期性的打開隨機端口並向zabbix agent服務器的10050發起tcp連接，然后發送獲取監控項數據的指令，即zabbix server發送什么指令那么zabbix agent就收集什么數據，zabbix server什么時候發送zabbix agent就什么時候采集，zabbix server不發送zabbix agent就一直不響應，所以zabbix agent也不用關心其監控項和數據采集周期間隔時間。
被動模式的優點就是配置簡單，安裝后即可使用，因此也成為zabbix 的默認工作模式，但是被動模式的最大問題就是會加大zabbix server的工作量，在數百甚至數千台服務器的環境下會導致zabbix server需要輪訓向每個zabbix agent發送數據采集指令，如果zabbix server負載很高還會導致不能及時獲取到最新數據，但由於無需其他復雜配置，被設置為了默認的工作方式。
主動模式：
主動模式是由zabbix agent主動向zabbix server的10051端口發起tcp連接請求，因此主動模式下必須在zabbixagent配置文件中指定zabbix server的IP或者主機名(必須可以被解析為IP地址)，在連接到zabbix server之前zabbix agent是不知道自己要采集那些數據以及間隔多久采集一次數據的，然后在連接到zabbix server以后獲取到自己的監控項和數據采集間隔周期時間，然后再根據監控項采集數據並返回給zabbix server，在主動模式下不再需要zabbix serve向zabbix agent發起連接請求，因此主動模式在一定程度上可減輕zabbix server打開的本地隨機端口和進程數，在一定程度就減輕看zabbix server的壓力。
二. 如何自定義監控項：
-
先通過腳本或命令獲取監控項數據
-
將腳本或命令添加到zabbix agent配置文件中的自定義監控項並重啟
UserParameter=n50[*],/bin/bash /data/scripts/n50.sh $1
UserParameter=n51,/usr/bin/python3 /data/scripts/n50.py
UserParameter=tcp_status[*],/bin/bash /etc/zabbix/zabbix_agentd.d/tcp_status.sh $1 $2
-
在zabbix server使用zabbix_get命令測試監控項能否獲取到數據
zabbix_get -s 10.0.0.107 -p 10050 -k "tcp_status["tcp_status","ESTAB"]"
-
在zabbix web添加監控項、觸發器、圖形或者創建模板
-
驗證數據
