网络设备配置
将 syslog-ip 替换成服务器的IP地址。
Huawei
info-center loghost source interface
info-center loghost syslog-ip local-time facility local6
H3C
info-center loghost source interface
info-center loghost syslog-ip facility local5
Aruba

logging network subcat all level warnings
logging security subcat all level warnings
logging security subcat ids level warnings
logging security subcat ids-ap level warnings
logging system subcat all level warnings
logging user subcat all level warnings
logging wireless subcat all level warnings
logging 10.10.4.86 severity warnings facility local3
CISCO

logging syslog-ip
logging facility local4
logging source-interface e0本次以华为交换机为例，首先登录交换机，设置日志收集服务器地址：
1、设置日志服务器IP地址
<S5735-EsxiMGT-SW1>system-view
Enter system view, return user view with Ctrl+Z.
[S5735-EsxiMGT-SW1]display current-configuration | in info
info-center loghost source Vlanif100
snmp-agent sys-info version v2c
undo snmp-agent sys-info version v3
[S5735-EsxiMGT-SW1]info-center loghost 10.10.200.35
[S5735-EsxiMGT-SW1]display current-configuration | in info
info-center loghost source Vlanif100
info-center loghost 10.10.200.35
snmp-agent sys-info version v2c
undo snmp-agent sys-info version v3
之后登录logstash服务器，配置conf
[root@node3 ~]# cd /etc/logstash/conf.d/
[root@node3 conf.d]# vim switch.conf
input{tcp { port => 5002type => "Cisco"}udp { port => 514type => "HUAWEI"}udp { port => 5002type => "Cisco"}udp { port => 5003type => "H3C"}
}
filter {if [type] == "Cisco" {grok {match => { "message" => "<%{BASE10NUM:syslog_pri}>%{NUMBER:log_sequence}: .%{SYSLOGTIMESTAMP:timestamp}: %%{DATA:facility}-%{POSINT:severity}-%{CISCO_REASON:mnemonic}: %{GREEDYDATA:message}" }match => { "message" => "<%{BASE10NUM:syslog_pri}>%{NUMBER:log_sequence}: %{SYSLOGTIMESTAMP:timestamp}: %%{DATA:facility}-%{POSINT:severity}-%{CISCO_REASON:mnemonic}: %{GREEDYDATA:message}" }add_field => {"severity_code" => "%{severity}"}overwrite => ["message"]}
}elseif [type] == "H3C" {grok {match => { "message" => "<%{BASE10NUM:syslog_pri}>%{SYSLOGTIMESTAMP:timestamp} %{YEAR:year} %{DATA:hostname} %%%{DATA:vvmodule}/%{POSINT:severity}/%{DATA:digest}: %{GREEDYDATA:message}" }remove_field => [ "year" ]add_field => {"severity_code" => "%{severity}"}overwrite => ["message"]}
}elseif [type] == "HUAWEI" {grok {match => { "message" => "<%{BASE10NUM:syslog_pri}>%{SYSLOGTIMESTAMP:timestamp} %{DATA:hostname} %%%{DATA:ddModuleName}/%{POSINT:severity}/%{DATA:Brief}:%{GREEDYDATA:message}"}match => { "message" => "<%{BASE10NUM:syslog_pri}>%{SYSLOGTIMESTAMP:timestamp} %{DATA:hostname} %{DATA:ddModuleName}/%{POSINT:severity}/%{DATA:Brief}:%{GREEDYDATA:message}"}remove_field => [ "timestamp" ]add_field => {"severity_code" => "%{severity}"}overwrite => ["message"]}
}
#mutate {

}
output{elasticsearch {index =>"syslog-%{+YYYY.MM.dd}"hosts => ["10.10.200.33:9200","10.10.200.34:9200","10.10.200.35:9200"]}
}
修改后，重启Logstash
登录ELK，检查数据
