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>>.
|
|
|
|

// tag::enable-collection[]
|
|
Set `xpack.monitoring.collection.enabled` to `true` on the
|
|
production cluster. By default, it is is disabled (`false`).
|
|
|
|
You can use the following APIs to review and change this setting:
|
|
|
|
[source,console]
|
|
----------------------------------
|
|
GET _cluster/settings
|
|
|
|
PUT _cluster/settings
|
|
{
|
|
"persistent": {
|
|
"xpack.monitoring.collection.enabled": true
|
|
}
|
|
}
|
|
----------------------------------
|
|
|
|
If {es} {security-features} are enabled, you must have `monitor` cluster privileges to
|
|
view the cluster settings and `manage` cluster privileges to change them.
|
|
// end::enable-collection[]
|
|
|
|

The `modules.d/elasticsearch-xpack.yml` file contains the following settings:
|
|
|
|
[source,yaml]
|
|
----------------------------------
|
|
- module: elasticsearch
|
|
xpack.enabled: true
|
|
period: 10s
|
|
hosts: ["http://localhost:9200"] <1>
|
|
#scope: node <2>
|
|
#username: "user"
|
|
#password: "secret"
|
|
#ssl.enabled: true
|
|
#ssl.certificate_authorities: ["/etc/pki/root/ca.pem"]
|
|
#ssl.certificate: "/etc/pki/client/cert.pem"
|
|
#ssl.key: "/etc/pki/client/cert.key"
|
|
#ssl.verification_mode: "full"
|
|
xpack.enabled: true
|
|
----------------------------------
|
|
<1> By default, the module collects {es} monitoring metrics from
|
|
`http://localhost:9200`. If that host and port number are not correct, you must
|
|
update the `hosts` setting. If you configured {es} to use encrypted
|
|
communications, you must access it via HTTPS. For example, use a `hosts` setting
|
|
like `https://localhost:9200`.
|
|
<2> By default, `scope` is set to `node` and each entry in the `hosts` list
|
|
indicates a distinct node in an {es} cluster. If you set `scope` to `cluster`,
|
|
each entry in the `hosts` list indicates a single endpoint for a distinct {es}
|
|
cluster (for example, a load-balancing proxy fronting the cluster).
|
|
|
|
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
|
|
<<built-in-roles,`remote_monitoring_collector` built-in role>>.
|
|
Alternatively, use the
|
|
<<built-in-users,`remote_monitoring_user` built-in user>>.
|
|
|
|
.. Add the `username` and `password` settings to the {es} module configuration
|
|
file.
|
|
|
|
.. If TLS is enabled on the HTTP layer of your {es} cluster, you must either use https as the URL scheme in the `hosts` setting or add the `ssl.enabled: true` setting. Depending on the TLS configuration of your {es} cluster, you might also need to specify {metricbeat-ref}/configuration-ssl.html[additional ssl.*] settings.
|
|
--
|
|
|
|
. Optional: Disable the system module in {metricbeat}.
|
|
+
|
|
--
|
|
By default, the {metricbeat-ref}/metricbeat-module-system.html[system module] is
|
|
enabled. The information it collects, however, is not shown on the *Monitoring*
|
|
page in {kib}. Unless you want to use that information for other purposes, run
|
|
the following command:
|
|
|
|
["source","sh",subs="attributes,callouts"]
|
|
----------------------------------------------------------------------
|
|
metricbeat modules disable system

. 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:
|
|
# Array of hosts to connect to.
|
|
hosts: ["http://es-mon-1:9200", "http://es-mon2:9200"] <1>
|
|
|
|
# Optional protocol and basic auth credentials.
|
|
#protocol: "https"
|
|
#username: "elastic"
|
|
#password: "changeme"
|
|
----------------------------------
|
|
<1> In this example, the data is stored on a monitoring cluster with nodes
|
|
`es-mon-1` and `es-mon-2`.
|
|
|
|
If you configured the monitoring cluster to use encrypted communications, you
|
|
must access it via HTTPS. For example, use a `hosts` setting like
|
|
`https://es-mon-1:9200`.
|
|
|
|
IMPORTANT: The {es} {monitor-features} use ingest pipelines, therefore the
|
|
cluster that stores the monitoring data must have at least one
|
|
<<ingest,ingest node>>.
|
|
|
|
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
|
|
<<built-in-roles,`remote_monitoring_agent` built-in role>>.
|
|
Alternatively, use the
|
|
<<built-in-users,`remote_monitoring_user` built-in user>>.
|
|
|
|
.. Add the `username` and `password` settings to the {es} output information in
|
|
the {metricbeat} configuration file.
|
|
|
|
For more information about these configuration options, see
|
|
{metricbeat-ref}/elasticsearch-output.html[Configure the {es} output].

|

Set `xpack.monitoring.elasticsearch.collection.enabled` to `false` on the
|
|
production cluster.
|
|
|
|
You can use the following API to change this 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.
