I am testing the Graylog appliance “graylog-3.3.14-1.ova” and I am also a Linux newbie.
The input “syslog udp” (comes directly from the graylog server) is displayed correctly.
The firewall is inactive.
The beats input from a windows server is not displayed. However, you can see that the network counter is counting up.
First check if the traffic(messages) from the windows server reaches the Graylog Server or not?
Is the port 5044 open?
sudo tcpdump -i lo host and udp/TCP port 5044
sudo netstat -peanut | grep “:5044” https://docs.graylog.org/docs/collect
here ist the result from: systemctl status elasticsearch:
ubuntu@graylog:~$ systemctl status elasticsearch

###################### Winlogbeat Configuration Example ########################
# This file is an example configuration file highlighting only the most common
# options. The winlogbeat.reference.yml file from the same directory contains
# all the supported options with more comments. You can use it as a reference.
#
# You can find the full configuration reference here:
# https://www.elastic.co/guide/en/beats/winlogbeat/index.html
# ======================== Winlogbeat specific options =========================
# event_logs specifies a list of event logs to monitor as well as any
# accompanying options. The YAML data type of event_logs is a list of
# dictionaries.
#
# The supported keys are name (required), tags, fields, fields_under_root,
# forwarded, ignore_older, level, event_id, provider, and include_xml. Please
# visit the documentation for the complete details of each option.

# The tags of the shipper are included in their own field with each
# transaction published.

# ================================= Dashboards =================================
# These settings control loading the sample dashboards to the Kibana index. Loading
# the dashboards is disabled by default and can be enabled either by setting the
# options here or by using the `setup` command.
#setup.dashboards.enabled: false
# The URL from where to download the dashboards archive. By default this URL
# has a value which is computed based on the Beat name and version. For released
# versions, this URL points to the dashboard archive on the artifacts.elastic.co
# website.

# =================================== Kibana ===================================
# Starting with Beats version 6.0.0, the dashboards are loaded via the Kibana API.
# This requires a Kibana endpoint configuration.
setup.kibana:
# Kibana Host
# Scheme and port can be left out and will be set to the default (http and 5601)
# In case you specify and additional path, the scheme is required: http://localhost:5601/path
# IPv6 addresses should always be defined as: https://[2001:db8::1]:5601

# Kibana Space ID
# ID of the Kibana Space into which the dashboards should be loaded. By default,
# the Default Space will be used.

# =============================== Elastic Cloud ================================
# These settings simplify using Winlogbeat with the Elastic Cloud (https://cloud.elastic.co/).
# The cloud.id setting overwrites the `output.elasticsearch.hosts` and
# `setup.kibana.host` options.
# You can find the `cloud.id` in the Elastic Cloud web UI.
#cloud.id:
# The cloud.auth setting overwrites the `output.elasticsearch.username` and
# `output.elasticsearch.password` settings. The format is `<user>:<pass>`.

#logging.selectors: ["*"]
# ============================= X-Pack Monitoring ==============================
# Winlogbeat can export internal metrics to a central Elasticsearch monitoring
# cluster. This requires xpack monitoring to be enabled in Elasticsearch. The
# reporting is disabled by default.
# Set to true to enable the monitoring reporter.
#monitoring.enabled: false
# Sets the UUID of the Elasticsearch cluster under which monitoring data for this
# Winlogbeat instance will appear in the Stack Monitoring UI. If output.elasticsearch
# is enabled, the UUID is derived from the Elasticsearch cluster referenced by output.elasticsearch.
#monitoring.cluster_uuid:
# Uncomment to send the metrics to Elasticsearch. Most settings from the
# Elasticsearch output are accepted here as well.
# Note that the settings should point to your Elasticsearch *monitoring* cluster.
# Any setting that is not set is automatically inherited from the Elasticsearch
# output configuration, so if you have the Elasticsearch output configured such
# that it is pointing to your Elasticsearch monitoring cluster, you can simply
# uncomment the following line.

Belt and braces, I would first test the input by running on the following command on the Graylog server itself:
echo “Hello Beats Input, please work locally. Regards, Merida” | nc -w 1 -u [Graylog host IP or name] 5044
And then run the same command from the server on which your filebeats instance is installed:
echo “Hello Beats Input, please work from remote machine. Regards, Merida” | nc -w 1 -u [Graylog host IP or name] 5044
If both of those work, you know the network connectivity is not the issue. The next most likely issue is that Filebeats does not actually have permission to read the logs you are trying to ingest.
Set the CHMOD of those log files appropriately and reboot Filebeat.
Filebeat writes a log file, might be worth looking at that.
This section I had to add is for my logging, so if there is a problem I can grab the logs to find out what going wrong or to fix an issue. I did create the directory before starting winlogbeat service and make sure WinLogBeat service has access to the directory.
logging.level: debug <--- once your all set you should change this to INFO
logging.to_files: true
logging.files:
path: C:\winlogbeat\logs
name: winlogbeat.log
Since your a beginner make sure the indents in your winlogbeat.yml file is correct. YAML files are touchy about indents and spaces. If you get the logging to work for winlogbeat there might be something in there that can help. here are some more steps you can do.
VALIDATE CONFIGURATION
NOTE: run as administrator for powershell, it will help. PS C:\Program Files\Winlogbeat> .\winlogbeat.exe test config -c .\winlogbeat.yml -e
If script execution is disabled on your system, you need to set the execution policy for the current session to allow the script to run. For example:
You won’t see any message in the terminal after you send that command, but you should find a message reaches Graylog to that port. You might try it with 127.0.0.1 if you are running the command directly on the Graylog server.
