Using Fortinet Integration in Logstash

[b0r1s]

Hey everyone o/

I'm using that conf I found on this topic for parsing logs from FortigateFW with Logstash:

input {
udp {
port => 514
type => "forti_log"
tags => ["FortiGateFW"]
}
}
#THE BEGINNING DOESN'T FORMAT TO CODE AND I DON'T KNOW WHY

    filter {
    #The Fortigate syslog contains a type field as well, we'll need to rename that field in order for this to work
    if [type] == "forti_log" {

    grok {
    		match => ["message", "%{SYSLOG5424PRI:syslog_index}%{GREEDYDATA:message}"]
    		overwrite => [ "message" ]
    		tag_on_failure => [ "forti_grok_failure" ]
    	}


        kv {
    source => "message"
    value_split => "="

    #Expects you have csv enable set on your Fortigate. If not I think you'll have to change it to " " but I didn't test that.
    field_split => ","
    }

    mutate {

    #I want to use the timestamp inside the logs instead of Logstash's timestamp so we'll first create a new field containing the date and time fields from the syslog before we convert that to the @timestamp field
    add_field => { "temp_time" => "%{date} %{time}" }
    #The syslog contains a type field which messes with the Logstash type field so we have to rename it.
    rename => { "type" => "ftg_type" }
    rename => { "subtype" => "ftg_subtype" }
    add_field => { "type" => "forti_log" }
    convert => { "rcvdbyte" => "integer" }
    convert => { "sentbyte" => "integer" }
    }

    date {
    match => [ "temp_time", "yyyy-MM-dd HH:mm:ss" ]
    timezone => "UTC"
    target => "@timestamp"
    }

    mutate {

    #add/remove fields as you see fit.
    remove_field => ["syslog_index","syslog5424_pri","path","temp_time","service","date","time","sentpkt","rcvdpkt","log_id","message","poluuid"]
    }
    }
    }

    output {
    stdout { codec => rubydebug }
    if [type] == "forti_log" {
    elasticsearch {
    hosts => ["XXX.XXX.XXX.XXX:9200", "XXX.XXX.XXX.XXX:9200", "XXX.XXX.XXX.XXX:9200"]
    http_compression => "true"
    index => "forti-%{+YYYY.MM.dd}"
    #user => "elastic"
    #password => "elastic"
    #template => "/usr/share/logstash/bin/forti.json"
    #template_name => "forti-*"
    }
    }
    }

And at this moment I think all parsing is ok (at last with one fortigate fw. when I add a second on the same conf, some fields parse with errors, but it's for another topic, I think some config on 2nd fw logs is different) .

The point is:
Learning more about ELK I found yourkibanahost /app/fleet#/integrations/detail/fortinet-0.8.0/overview integration and I don't know how to use it with Logstash. I would like to test it for compare the results.
*I think all kibana UI show this integration, but you can view more about here

I need to convert like this doc explains?
Or something starting by this doc?

I have a lot to learn and sometimes I get confused on what to focus... The first mission on my log-server is to get powerfull insights with fortigate logs/dashboards so I'm trying to do my best on this

Please edit your post, select the logstash configuration (only the logstash configuration) and click on </> in the tool bar above the edit pan. That will change the appearance from

udp {
port => 514
type => "forti_log"
tags => ["FortiGateFW"]
}

which I find unreadable to

udp {
  port => 514
  type => "forti_log"
  tags => ["[spoiler]FortiGateFW[/spoiler]"]
}

Also, the link you posted is to the local hostname mykibana, so nobody else can follow it.

The integration you linked to is for filebeat, not logstash. You can have filebeat listen on a network port and tell your Fortinet device to send syslog messages to it. filebeat can send the results to elasticsearch. You may not need to use logstash at all. I suggest you set that up first. If you find you need additional processing then you may be able to do it with logstash.
