=== Collecting {es} monitoring data with {metricbeat}

|
|
In 6.5 and later, you can use {metricbeat} to collect data about {es}
|
|
and ship it to the monitoring cluster, rather than routing it through exporters
|
|
as described in <<collecting-monitoring-data>>.
|
|
|
|
image::monitoring/images/metricbeat.png[Example monitoring architecture]
|
|
|
|
To learn about monitoring in general, see
|
|
{stack-ov}/xpack-monitoring.html[Monitoring the {stack}].
|
|
|
|
. Enable the collection of monitoring data. Set
|
|
`xpack.monitoring.collection.enabled` to `true` on each node in the production
|
|
cluster. By default, it is is disabled (`false`).
|
|
+
|
|
--
|
|
NOTE: You can specify this setting in either the `elasticsearch.yml` on each
|
|
node or across the cluster as a dynamic cluster setting. If {es}
|
|
{security-features} are enabled, you must have `monitor` cluster privileges to
|
|
view the cluster settings and `manage` cluster privileges to change them.
|
|
|
|
For example, you can use the following APIs to review and change this setting:
|
|
|
|
[source,js]
|
|
----------------------------------
|
|
GET _cluster/settings
|
|
|
|
PUT _cluster/settings
|
|
{
|
|
"persistent": {
|
|
"xpack.monitoring.collection.enabled": true
|
|
}
|
|
}
|
|
----------------------------------
|
|
// CONSOLE
|
|
|
|
For more information, see <<monitoring-settings>> and <<cluster-update-settings>>.
|
|
--
|
|
|
|
. Disable the default collection of {es} monitoring metrics. Set
|
|
`xpack.monitoring.elasticsearch.collection.enabled` to `false` on each node in
|
|
the production cluster.

Leave `xpack.monitoring.enabled` set to its default value (`true`).

. On each {es} node in the production cluster:
|
|
|
|
.. {metricbeat-ref}/metricbeat-installation.html[Install {metricbeat}].
|
|
|
|
.. Enable the {es} module in {metricbeat}. +
|
|
+
|
|
--
|
|
For example, to enable the default configuration in the `modules.d` directory,
|
|
run the following command:
|
|
|
|
["source","sh",subs="attributes,callouts"]
|
|
----------------------------------------------------------------------
|
|
metricbeat modules enable elasticsearch-xpack
|
|
----------------------------------------------------------------------
|
|
|
|
For more information, see
|
|
{metricbeat-ref}/configuration-metricbeat.html[Specify which modules to run] and
|
|
{metricbeat-ref}/metricbeat-module-elasticsearch.html[{es} module].
|
|
--
|
|
|
|
.. By default the module will collect {es} monitoring metrics from `http://localhost:9200`.
|
|
If the local {es} node has a different address, you must specify it via the `hosts` setting
|
|
in the `modules.d/elasticsearch-xpack.yml` file.
|
|
|
|
.. If Elastic {security-features} are enabled, you must also provide a user ID
|
|
and password so that {metricbeat} can collect metrics successfully.
|
|
|
|
... Create a user on the production cluster that has the
|
|
{stack-ov}/built-in-roles.html[`remote_monitoring_collector` built-in role].
|
|
Alternatively, use the {stack-ov}/built-in-users.html[`remote_monitoring_user` built-in user].
|
|
|
|
... Add the `username` and `password` settings to the {es} module configuration
|
|
file.
|
|
+
|
|
--
|
|
For example, add the following settings in the `modules.d/elasticsearch-xpack.yml` file:
|
|
|
|
[source,yaml]
|
|
----------------------------------
|
|
- module: elasticsearch
|
|
...
|
|
username: remote_monitoring_user
|
|
password: YOUR_PASSWORD
|
|
----------------------------------
|
|
--
|
|
|
|
.. If you configured {es} to use <<configuring-tls,encrypted communications>>,
|
|
you must access it via HTTPS. For example, use a `hosts` setting like
|
|
`https://localhost:9200` in the `modules.d/elasticsearch-xpack.yml` file.
|
|
|
|
.. Identify where to send the monitoring data. +
|
|
+
|
|

|
|
TIP: In production environments, we strongly recommend using a separate cluster
|
|
(referred to as the _monitoring cluster_) to store the data. Using a separate
|
|
monitoring cluster prevents production cluster outages from impacting your
|
|
ability to access your monitoring data. It also prevents monitoring activities
|
|
from impacting the performance of your production cluster.
|
|
|
|
For example, specify the {es} output information in the {metricbeat}
|
|
configuration file (`metricbeat.yml`):
|
|
|
|
[source,yaml]
|
|
----------------------------------
|
|
output.elasticsearch:
|
|
hosts: ["http://es-mon-1:9200", "http://es-mon2:9200"] <1>
|
|
----------------------------------
|
|
<1> In this example, the data is stored on a monitoring cluster with nodes
|
|
`es-mon-1` and `es-mon-2`.
|
|
|
|
IMPORTANT: The {es} {monitor-features} use ingest pipelines, therefore the
|
|
cluster that stores the monitoring data must have at least one
|
|
<<ingest,ingest node>>.
|
|
|
|
For more information about these configuration options, see
|
|
{metricbeat-ref}/elasticsearch-output.html[Configure the {es} output].
|
|
--
|
|
|
|
.. If {es} {security-features} are enabled on the monitoring cluster, you
|
|
must provide a valid user ID and password so that {metricbeat} can send metrics
|
|
successfully.
|
|
|
|
... Create a user on the monitoring cluster that has the
|
|
{stack-ov}/built-in-roles.html[`remote_monitoring_agent` built-in role].
|
|
Alternatively, use the
|
|
{stack-ov}/built-in-users.html[`remote_monitoring_user` built-in user].
|
|
|
|
... Add the `username` and `password` settings to the {es} output information in
|
|
the {metricbeat} configuration file (`metricbeat.yml`):
|
|
+
|
|
--
|
|
[source,yaml]
|
|
----------------------------------
|
|
output.elasticsearch:
|
|
...
|
|
username: remote_monitoring_user
|
|
password: YOUR_PASSWORD
|
|
----------------------------------
|
|
--
|
|
|
|
.. If you configured the monitoring cluster to use
|
|
<<configuring-tls,encrypted communications>>, you must access it via
|
|
HTTPS. For example, use a `hosts` setting like `https://es-mon-1:9200` in the
|
|
`metricbeat.yml` file.
