I checked several time my filebeat.yml, logstash.yml, elasticsearch.yml and kibana.yml and I couldn't find any error in line 9... do you know how I could fix this error?

Thanks!

The error is not in filebeat.yml itself. It looks like filebeat is configured with config reloading. It complains about one of the files found in the reloading-directory to be invalid yaml.

robegome · August 27, 2018, 9:38pm

that is correct, I enble the reloading config in my filebeat.yml

#============================= Filebeat modules ===============================

filebeat.config.modules:

Glob pattern for configuration loading

path: ${path.config}/modules.d/*.yml

Set to true to enable config reloading

reload.enabled: true

Period on which files under path should be checked for changes

#reload.period: 10s

So, if that is not an error... I assume this thread could be closed

steffens · August 28, 2018, 2:01pm

It is an error. There is an invalid configuration file in your modules.d directory. Unfortunately the error message does not report the actual file that failed

I created an issue on the actual error message being not very helpful: #8122.

robegome · August 28, 2018, 2:59pm

Hi Steffen, ok got it... if it is useful i am going to paste the three files (.conf) that I am using in Logstash (and beats):

input.conf
cat /etc/logstash/conf.d/input.conf

input {
beats {
port => 5044
}
}

filter.conf
cat /etc/logstash/conf.d/filter.conf

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}" ]
add_field => [ "received_from", "%{host}" ]
}
syslog_pri { }
date {
match => [ "syslog_timestamp", "MMM d HH:mm:ss", "MMM dd HH:mm:ss" ]
}
}
}

output.conf
cat /etc/logstash/conf.d/output.conf

output {
elasticsearch {
hosts => ["localhost:9200"]
sniffing => true
manage_template => false
index => "%{[@metadata][beat]}-%{+YYYY.MM.dd}"
document_type => "%{[@metadata][type]}"
}
}

I hope this could help to resolve the issue... THANKS!

... also I am adding the info that I have regarding my modules.d

output enable modules:

/usr/share/filebeat/bin/filebeat --path.config=/etc/filebeat/ modules list

Enabled:
    nginx
    system

Disabled:
apache2
auditd
elasticsearch
icinga
iis
kafka
kibana
logstash
mongodb
mysql
osquery
postgresql
redis
traefik

this is the content in NGINX:

cat nginx.yml

- module: nginx
  # Access logs
  access:
    enabled: true

    # Set custom paths for the log files. If left empty,
    # Filebeat will choose the paths depending on your OS.
    var.paths ["/path/to/log/nginx/access.log*"]

  # Error logs
  error:
    enabled: true

    # Set custom paths for the log files. If left empty,
    # Filebeat will choose the paths depending on your OS.
    var.paths: ["/path/to/log/nginx/error.log*"]

this is the content in SYSTEM:

cat system.yml

- module: system
  # Syslog
  syslog:
    enabled: true

    # Set custom paths for the log files. If left empty,
    # Filebeat will choose the paths depending on your OS.
    #var.paths:

    # Convert the timestamp to UTC. Requires Elasticsearch >= 6.1.
    #var.convert_timezone: false

  # Authorization logs
  auth:
    enabled: true

    # Set custom paths for the log files. If left empty,
    # Filebeat will choose the paths depending on your OS.
    #var.paths:

    # Convert the timestamp to UTC. Requires Elasticsearch >= 6.1.
    #var.convert_timezone: false

You can test yaml syntax in filebeat configuration files using some yaml linters. E.g. a web based linter can be found at http://www.yamllint.com.

The problem is in your nginx configuration. You are missing the : symbol at line 9.

Your config is:

    var.paths ["/path/to/log/nginx/access.log*"]

but it must be:

    var.paths: ["/path/to/log/nginx/access.log*"]

robegome · August 28, 2018, 9:45pm

yes, you are right... there is a typo in that line!!

I appreciate your help and now all is working better... the error about Error loading config: invalid config: yaml: line 9: could not find expected ':' has been gone!

THANKS!!!
