hi
whenever i reboot or shut my machine it hangs at this message
job logstash.service/stop running
it takes forever .. its a test lab and hardly one device is sending a netflow and winlog beat to it.
last time i left it at this message for 90 minutes before i have to force shut my machine. now everytime it takes this long. what could be the reason for it and how to fix it ?

netflow@elastic:~$
This is an authentication error, some of your elasticsearch outputs have the wrong authentication credentials.
Logstash will keep trying to connect and since when you shutdown logstash it will also try to publish all events it has in the queues, this can hang out the shutdown.
You need to fix the authentication issues and see if this behaviour persists.
Probably unrelated, both Kibana and Logstash works as Elasticsearch Clients.
The issue is that Logstash is trying to connect to your Elasticsearch in the address http://192.168.100.71:9200 and is receiving a 401 error, which means that the request was unauthorized because the username or password is wrong.
You need to check your logstash configuration files and look into your elasticsearch output.
ok i checked that i have elasticsearch and kibna on https
in the output section i have below configs
###################### Filebeat Configuration Example #########################
# This file is an example configuration file highlighting only the most common
# options. The filebeat.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/filebeat/index.html
# For more available modules and options, please see the filebeat.reference.yml sample
# configuration file.

# all the transactions sent by a single shipper in the web interface.
#name:
# The tags of the shipper are included in their own field with each
# transaction published.
#tags: ["service-X", "web-tier"]
# Optional fields that you can specify to add additional information to the
# output.
#fields:
# env: staging
# ================================= Dashboards =================================

# 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.
#setup.dashboards.url:
# =================================== 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
host: "http://localhost:5601"
# Kibana Space ID
# ID of the Kibana Space into which the dashboards should be loaded. By default,
# the Default Space will be used.
#space.id:
# =============================== Elastic Cloud ================================
# These settings simplify using Filebeat 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>`.
#cloud.auth:
# ================================== Outputs ===================================
# Configure what output to use when sending the data collected by the beat.
# ---------------------------- Elasticsearch Output ----------------------------
output.elasticsearch:
# Array of hosts to connect to.
hosts: ["localhost:9200"]
# Protocol - either `http` (default) or `https`.
protocol: "https"
# Authentication credentials - either API key or username/password.
#api_key: "id:api_key"

- add_kubernetes_metadata: ~
# ================================== Logging ===================================
# Sets log level. The default log level is info.
# Available log levels are: error, warning, info, debug
#logging.level: debug
# At debug level, you can selectively enable logging only for some components.
# To enable all selectors use ["*"]. Examples of other selectors are "beat",
# "publisher", "service".
#logging.selectors: ["*"]
# ============================= X-Pack Monitoring ==============================
# Filebeat 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
# Filebeat 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.
#monitoring.elasticsearch:
# ============================== Instrumentation ===============================
# Instrumentation support for the filebeat.
#instrumentation:
# Set to true to enable instrumentation of filebeat.
#enabled: false
# Environment in which filebeat is running on (eg: staging, production, etc.)
#environment: ""
# APM Server hosts to report instrumentation results to.

# ================================= Migration ==================================
# This allows to enable 6.7 migration aliases
#migration.6_to_7.enabled: true
The first one is a filebeat config, the other is an elasticsearch.yml config and the last one is a kibana.yml config.
Your Elasticsearch is not using https as it is not configured to do so, your Kibana is using https, but it connects to elasticsearch using http as you can verify by the elasticsearch.hosts configuration.
With these configurations, your Filebeat is not working, it will not be able to send data to Elastisearch as it is configured to use https, but your cluster is using http.
You need to look in your logstash configuration, if you installed it as a package you will have a logstash.yml and a pipelines.yml files in /etc/logstash.
The logstash.yml is used to configure the Logstash service, the second one, pipelines.yml, is used to tell Logstash which pipelines it should run and where their configurations are stored.
