ELK 收集交换机日志（以华为交换机为例）

大概思路

　　交换机日志----> 服务器---->服务器rsyslog设置指定存储路径文件--->随后就跟elk 监控本机日志一样了

huawei switch：

#指定发送消息基本，表示从0-7都发送
info-center source default channel 2 log level debugging
#指定从哪个接口发送
info-center loghost source Vlanif1
#指定远程 ELK 服务器ip
info-center loghost 192.168.1.137

ELK :

修改系统日志的配置文件
vim /etc/rsyslog.conf
#启用udp 514端口监听。
$ModLoad imudp
$UDPServerRun 514

把来自两个交换机的日志分别放入到指定的log文件中。

:fromhost-ip,isequal, "192.168.1.88"               /var/log/huawei/route.log
:fromhost-ip,isequal, "192.168.1.xx"               /var/log/huawei/xxxx.log

重启rsyslog服务

 systemctl restart rsyslog 

logstash：

编辑配置文件

cdops运维博客

vim /etc/logstash/conf.d/testroute.conf 
input {
    syslog {
        type => "/var/log/huawei/route.log"
        port => 10515
    }
}
output {
    #stdout {
    #    codec => rubydebug
    #}
    elasticsearch {
        hosts => ["192.168.1.137:9200"]
        index => "test-route-%{+YYYY.MM}"
    }
}

修改系统日志的配置文件

vim /etc/rsyslog.conf
#### RULES ####
*.* @@192.168.1.137:10515

重启下日志服务

systemctl restart rsyslog

运行配置文件

/usr/share/logstash/bin/logstash --path.settings /etc/logstash -f /etc/logstash/conf.d/testroute.conf &

稍等大概2-3分钟出现一下内容
