Zabbix icmp pinger processes more than 75% busy

Zabbix icmp pinger processes more than 75% busy

 

Zabbix server报"Zabbix icmp pinger processes more than 75% busy",之所以出现这个错误，因为昨天将模板Template Module ICMP Ping链接到Template OS Windows by Zabbix agent模板下和Template OS Linux by Zabbix agent模板下去了，而又忘记修改参数StartPingers，此时由于只有默认的一个线程在在ping，所以出现了这个告警。具体过程如下：

检查发现参数StartPingers没有配置，使用默认的值为1，此参数用于设置启用icmp协议PING主机方式启动线程数量。如果线程数量太小，监控的服务器数量过多的话，那么它有可能处于非常繁忙的状态。我们可以适当的调整其大小值

#grep StartPingers /etc/zabbix/zabbix_server.conf 

### Option: StartPingers

# StartPingers=1

调整参数大小后，重启Zabbix-Server服务，发现出错。具体情况如下所示：

# systemctl restart zabbix-server

Job for zabbix-server.service failed because the control process exited with error code.

See "systemctl status zabbix-server.service" and "journalctl -xe" for details.

检查错误信息，发现是参数设置错误，正确的参数是StartPingers，但是我漏掉了一个s，设置成StartPinger，出现了下面错误。修改后，重启Zabbix-Server服务，解决问题。

# journalctl -xe
