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
