Zabbix icmp pinger processes more than 75% busy
Zabbix server報"Zabbix icmp pinger processes more than 75% busy",之所以出現這個錯誤，因為昨天將模板Template Module ICMP Ping鏈接到Template OS Windows by Zabbix agent模板下和Template OS Linux by Zabbix agent模板下去了，而又忘記修改引數StartPingers，此時由于只有默認的一個執行緒在在ping，所以出現了這個告警，具體程序如下：
檢查發現引數StartPingers沒有配置，使用默認的值為1，此引數用于設定啟用icmp協議PING主機方式啟動執行緒數量，如果執行緒數量太小，監控的服務器數量過多的話，那么它有可能處于非常繁忙的狀態，我們可以適當的調整其大小值
#grep StartPingers /etc/zabbix/zabbix_server.conf ### Option: StartPingers# StartPingers=1
調整引數大小后，重啟Zabbix-Server服務，發現出錯，具體情況如下所示：
# systemctl restart zabbix-serverJob for zabbix-server.service failed because the control process exited with error code.
See "systemctl status zabbix-server.service" and "journalctl -xe" for details.
檢查錯誤資訊，發現是引數設定錯誤，正確的引數是StartPingers，但是我漏掉了一個s，設定成StartPinger，出現了下面錯誤，修改后，重啟Zabbix-Server服務，解決問題，
# journalctl -xe..............................................
