Hi Team,  
I am new in ELK, and I am looking to monitor my network infra logs, We are using below vendors devices :-  
Cisco  
Sonic wall  
Fortinet

At network end all log forwarding is configured on UDP 5014 port for all devices, logstash are receiving all logs, logstash config file:-

input {  
tcp {  
port =\> 5014  
type =\> syslog  
}  
udp {  
port =\> 5014  
type =\> syslog  
}  
}

filter {  
if [type] == "syslog" {  
grok {  
match =\> { "message" =\> "%{SYSLOGTIMESTAMP:syslog\_timestamp} %{SYSLOGHOST:syslog\_hostname} %{DATA:syslog\_program}(?:[%{POSINT:syslog\_pid}])?: %{GREEDYDATA:syslog\_message}" }  
add\_field =\> ["received\_at", "%{[@timestamp](https://github.com/timestamp)}" ]  
add\_field =\> ["received\_from", "%{host}"]  
}  
date {  
match =\> ["syslog\_timestamp", "MMM d HH:mm:ss", "MMM dd HH:mm:ss"]  
}  
}  
}

output {  
elasticsearch {  
hosts =\> ["localhost:9200"]  
user =\> elastic  
password =\> elastic  
}  
stdout { codec =\> rubydebug }  
}

Currently I am receiving all logs, but I have few query -

1. there is no such info like Firewall, route etc. so how can I identify device details ? or Is there any other better process to collect Network devices log
