Windows10字体路径，选择想更换的字体
将zabbix默认字体修改为自己想换的字体
代码语言：javascript复制# pwd
/usr/share/zabbix/assets/fonts //zabbix5.0字体文件目录
# ls
graphfont.ttf
# mv graphfont.ttf graphfont.ttf.bak
# ls
graphfont.ttf.bak
# ls
graphfont.ttf.bak simsun.ttc
# mv simsun.ttc simsun.ttf
# vim /usr/share/zabbix/include/defines.inc.php //脚本路径
define('ZBX_GRAPH_FONT_NAME', 'simsun'); // font file name
define('ZBX_FONT_NAME', 'simsun');
systemctl restart zabbix-server.serviceZabbix discoverer processes more than 75% busy
原因：
1. 配置的每个discovery任务在一定时间内占用1个discovery进程，而zabbix_server.conf中默认配置只有1个discovery(被注释，默认生效)；
2. 同时为了快速验证自动发现效果，将discovery任务的"Delay"时间由默认的3600s设置成60s。
解决方法
代码语言：javascript复制vi /etc/zabbix/zabbix_server.conf
### Option: StartDiscoverers
# Number of pre-forked instances of discoverers.
#
# Mandatory: no
# Range: 0-250
# Default:
StartDiscoverers=150zabbix server is not running
页面显示zabbix server is not running

使用预编译agent，直接安装即可
