I have the following infrastructure:
ELK installed as docker containers, each in its own container. And on a virtual machine running CentOS I installed nginx web server and Filebeat to collect the logs. I enabled the nginx module in filebeat.
> filebeat modules enable nginx
Before starting filebeat I set it up with elasticsearch and installed it's dashboards on kibana.
config file (I have removed unnecessary comments from the file):
filebeat.config.modules:
path: ${path.config}/modules.d/*.yml
reload.enabled: false
setup.kibana:
host: "172.17.0.1:5601"
output.elasticsearch:
hosts: ["172.17.0.1:9200"]
then to set it up in elasticsearch and kibana
> filebeat setup -e --dashboards
This works fine. In fact if I keep it this way everything works perfectly. I can use the collected logs in kibana and use the dashboards for NGinX I installed with the above command.
I want though to pass the logs through to Logstash. And here's my Logstash configuration uses the following pipelines:
- pipeline.id: filebeat
path.config: "config/filebeat.conf"
filebeat.conf:
input {
beats {
port => 5044
}
}
#filter {
# mutate {
# add_tag => ["filebeat"]
# }
#}
output {
elasticsearch {
hosts => ["elasticsearch0:9200"]
index => "%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
}
stdout { }
}
Making the logs go through Logstash the resulting log is just:
{

"@version" => "1",
"@timestamp" => 2019-02-20T13:34:06.886Z,

A lot of fields are missing from my object. There should have been many more structured information

From your logstash configuration, it doesn't look like you are parsing the log message.
There's an example in the logstash documentation on how to parse nginx logs:
Nginx Logs
The Logstash pipeline configuration in this example shows how to ship and parse access and error logs collected by the nginx Filebeat module.
input { beats { port => 5044 host => "0.0.0.0" } } filter { if [fileset][module] == "nginx" { if [fileset][name] == "access" { grok { match => { "message" => ["%{IPORHOST:[nginx][access][remote_ip]} - %{DATA:[nginx][access][user_name]} \[%{HTTPDATE:[nginx][access][time]}\] \"%{WORD:[nginx][access][method]} %{DATA:[nginx][access][url]} HTTP/%{NUMBER:[nginx][access][http_version]}\" %{NUMBER:[nginx][access][response_code]} %{NUMBER:[nginx][access][body_sent][bytes]} \"%{DATA:[nginx][access][referrer]}\" \"%{DATA:[nginx][access][agent]}\""] } remove_field => "message" } mutate { add_field => { "read_timestamp" => "%{@timestamp}" } } date { match => [ "[nginx][access][time]", "dd/MMM/YYYY:H:m:s Z" ] remove_field => "[nginx][access][time]" } useragent { source => "[nginx][access][agent]" target => "[nginx][access][user_agent]" remove_field => "[nginx][access][agent]" } geoip { source => "[nginx][access][remote_ip]" target => "[nginx][access][geoip]" } } else if [fileset][name] == "error" { grok { match => { "message" => ["%{DATA:[nginx][error][time]} \[%{DATA:[nginx][error][level]}\] %{NUMBER:[nginx][error][pid]}#%{NUMBER:[nginx][error][tid]}: (\*%{NUMBER:[nginx][error][connection_id]} )?%{GREEDYDATA:[nginx][error][message]}"] } remove_field => "message" } mutate { rename => { "@timestamp" => "read_timestamp" } } date { match => [ "[nginx][error][time]", "YYYY/MM/dd H:m:s" ] remove_field => "[nginx][error][time]" } } } }
I know it doesn't deal with why filebeat doesn't send to logstash the full object, but it should give a start on how to parse the nginx logs in logstash.
