Logstash-input-http_poller install

Elastic Stack Logstash

Could you please explain me how to install logstash-input-http_poller on a last ELK stack?
As I read I should to go to cd /usr/share/elasticsearch and after that use command bin/elasticsearch-plugin install logstash-input-http_poller. But I have a such output, how to install?

[root@localhost elasticsearch]# bin/elasticsearch-plugin install logstash-input-http_poller

Unless you are running a super old version of Logstash you shouldn't need to install it.

Also;

This is a Logstash plugin, not an Elasticsearch one, so the command you are running is not valid.

OK, I see.

Could you please help me to do the following: "collecting data periodically from multiple HTTP endpoints, and indexing the result in Elasticsearch"

4

Elasticsearch cannot connect to an endpoint like that, you need to use Logstash.

5

ok, could you help me to do that in logstash?

Maybe with help of metricbeat?

#==================== Elasticsearch template setting ==========================

setup.template.settings:
  index.number_of_shards: 1
  index.codec: best_compression
  #_source.enabled: false

#============================== 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` CLI flag or 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: "localhost:5601"

#================================ 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"]

  # Optional protocol and basic auth credentials.
  #protocol: "https"

# 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",
# "publish", "service".
#logging.selectors: ["*"]

#============================== Xpack Monitoring ===============================
# metricbeat 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.
#xpack.monitoring.enabled: false

# Uncomment to send the metrics to Elasticsearch. Most settings from the
# Elasticsearch output are accepted here as well. Any setting that is not set is
# automatically inherited from the Elasticsearch output configuration, so if you
# have the Elasticsearch output configured, you can simply uncomment the
# following line.
