Parsing nested JSON log file into ELK - Shodan.io Logs - json

Question

I'm trying to parse the nested JSON log file(Shodan.io)
I have parsed few values. Not able to parse below mentioned values:
hostnames
smb
smb_version
shares
temporary
type
name
comments
anonymous
transport
It will be good if can rid of value of 'raw':[0000, 0000]
You can check my sample log file here.
Below is my existing logstash filter configuration:
input {
file {
path => [ "/path/to/shodan-logs.json" ]
start_position => "beginning"
sincedb_path => "/dev/null"
}
}
filter {
json {
source => "message"
target => "json_parse"
add_tag => ["json_filter"]
tag_on_failure => ["json"]
}
grok {
break_on_match => false
add_tag => ["filtered"]
tag_on_failure => ["no_match_found"]
match => {
"message" => [
"%{IP:client_ip}",
"%{TIMESTAMP_ISO8601:timestamp}"
]
}
}
geoip {
source => "client_ip"
add_tag => ["geo_ip_found"]
tag_on_failure => ["geo_ip_not_found"]
}
useragent {
source => "message"
add_tag => ["user_details_found"]
}
# ruby {
# add_tag => ["ruby_filter"]
# code => '
# props = event.get("message")
# if props
# props.each { |x|
# key = x["key"]
# event.set("message.#{key}", x["value"])
# }
# end
# '
# }
mutate {
remove_field => [ "#timestamp", "path", "host", "#version" ]
}
}
output {
elasticsearch {
hosts => ["http://localhost:9200"]
user => "elastic"
password => "password"
index => "shodan-demo-%{+dd-MM-YYYY}"
}
stdout {
codec => rubydebug
}
}
Here are snapshots of my output on ELK
Note: I have tried below mentioned methods/filters
Commented ruby code filter, and it is not working.
Multiline input
json codec in input
