五，Metricbeat监控服务器
在客户端服务器安装metricbeat软件
rpm -ivh metricbeat-7.2.0-x86_64.rpm
修改/etc/metricbeat/metricbeat.yml配置文件，设置输出到logstash
output.logstash:
# The Logstash hosts
hosts: ["192.168.1.223:5044"]
/etc/metricbeat/modules.d/目录下有很多监控模块，这里只用到system这个模块，更多模块可参考ELK官网
修改/etc/metricbeat/modules.d/system.yml配置文件
- module: system #模块名称
period: 10s
metricsets: #监控项
- cpu
- load
- memory
- network
- process
- process_summary
- socket_summary
- core
- diskio
- socket
process.include_top_n:
by_cpu: 5 # include top 5 processes by CPU
by_memory: 5 # include top 5 processes by memory
- module: system
period: 1m
metricsets:
- filesystem
- fsstat
processors:
- drop_event.when.regexp:
system.filesystem.mount_point: '^/(sys|cgroup|proc|dev|etc|host|lib)($|/)'
- module: system
period: 15m
metricsets:
- uptime
