zabbix 监控内存使用情况

1、在客户端定义监控项

[root@zabbix-agent zabbix_java]# cat /apps/zabbix_agent/conf/zabbix_agentd.conf.d/mem.conf
UserParameter=mem_use_percent,free | awk 'NR==2{print $3/$2*100}'
UserParameter=mem_unuse_percent,free | awk 'NR==2{print 100-($3/$2*100)}'

[root@zabbix-agent ~]# systemctl restart zabbix-agent.service

root@zabbix-server:~# zabbix_get -s 192.168.1.122 -p 10050 -k "mem_use_percent"
8.58406
root@zabbix-server:~# zabbix_get -s 192.168.1.122 -p 10050 -k "mem_unuse_percent"
91.4103

2、在 Zabbix Server 添加监控项
