=== Collect {ls} monitoring data with {metricbeat}

In 7.3 and later, you can use {metricbeat} to collect data about {ls}
|
|
and ship it to the monitoring cluster, rather than routing it through the
|
|
production cluster as described in <<monitoring-internal-collection>>.
|
|
|
|
//NOTE: The tagged regions are re-used in the Stack Overview.
|
|
|
|
To collect and ship monitoring data:
|
|
|
|
. <<disable-default,Disable default collection of monitoring metrics>>
|
|
. <<configure-metricbeat,Install and configure {metricbeat} to collect monitoring data>>
|

==== Disable default collection of {ls} monitoring metrics
|
|
|

--

// tag::disable-ls-collection[]
|
|
The `monitoring` setting is in the {ls} configuration file (logstash.yml), but is
|
|
commented out:
|
|
|
|
[source,yaml]
|
|
----------------------------------
|
|
monitoring.enabled: false
|
|
----------------------------------
|
|
|
|
Remove the `#` at the beginning of the line to enable the setting.

. Configure the `logstash-xpack` module in {metricbeat}. +
|
|
+
|
|
--
|
|
// tag::configure-beat-module[]
|
|
The `modules.d/logstash-xpack.yml` file contains these settings:
|
|
|
|
[source,yaml]
|
|
----------------------------------
|
|
- module: logstash
|
|
metricsets:
|
|
- node
|
|
- node_stats
|
|
period: 10s
|
|
hosts: ["localhost:9600"]
|
|
#username: "user"
|
|
#password: "secret"
|
|
xpack.enabled: true
|
|
----------------------------------
|
|
|
|
Set the `hosts`, `username`, and `password` to authenticate with {ls}.
|
|
For other module settings, it's recommended that you accept the
|
|
defaults.
|
|
|
|
By default, the module collects {ls} monitoring data from
|
|
`localhost:9600`.
|
|
|
|
To monitor multiple {ls} instances, specify a list of hosts, for example:
|
|
[source,yaml]
|
|
----------------------------------
|
|
hosts: ["http://localhost:9601","http://localhost:9602","http://localhost:9603"]
|
|
----------------------------------
|
|
|
|
*Encrypted communications.* If you configured {ls} to use encrypted communications, you must access
|
|
it using HTTPS. For example, use a `hosts` setting like `https://localhost:9600`.
|
|
// end::configure-ls-module[]
|
|
|
|
// tag::remote-monitoring-user[]
|
|
*Elastic security.* If the Elastic {security-features} are enabled, provide a user
|
|
ID and password so that {metricbeat} can collect metrics successfully:
|
|
|
|
.. Create a user on the production cluster that has the
|
|
`remote_monitoring_collector` {ref}/built-in-roles.html[built-in role].
|
|
|
|
.. Add the `username` and `password` settings to the module configuration
|
|
file (`logstash-xpack.yml`).
|
|
// end::remote-monitoring-user[]
|
|
--
|
|
|
|
. Optional: Disable the system module in the {metricbeat}.
|
|
+
|
|
--
|
|
// tag::disable-system-module[]
|
|
By default, the {metricbeat-ref}/metricbeat-module-system.html[system module] is
|
|
enabled. The information it collects, however, is not shown on the
|
|
*Stack 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
|
|
----------------------------------------------------------------------
|
|
// end::disable-system-module[]

. 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 node.
|
|
|
|
If the {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
|
|
`remote_monitoring_agent` {ref}/built-in-roles.html[built-in role].
|
|
Alternatively, use the `remote_monitoring_user`
|
|
{ref}/built-in-users.html[built-in user].
|
|
+
|
|
TIP: If you're using index lifecycle management, the remote monitoring user
|
|
requires additional privileges to create and read indices. For more
|
|
information, see `<<feature-roles>>`.
|
|
|
|
.. 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].
