Monitoring settings in Elasticsearch
editMonitoring settings in Elasticsearch
editBy default, monitoring is enabled but data collection is disabled. To enable
data collection, use the xpack.monitoring.collection.enabled
setting.
You can configure these monitoring settings in the elasticsearch.yml
file. You
can also dynamically set some of these settings using the
cluster update settings API.
Cluster settings take precedence over settings in the elasticsearch.yml
file.
To adjust how monitoring data is displayed in the monitoring UI, configure
xpack.monitoring
settings in
kibana.yml
. To control how monitoring data is collected from
Logstash, configure
xpack.monitoring
settings
in logstash.yml
.
General Monitoring Settings
edit-
xpack.monitoring.enabled
-
Set to
true
(default) to enable Elasticsearch X-Pack monitoring for Elasticsearch on the node.To enable data collection, you must also set
xpack.monitoring.collection.enabled
totrue
. Its default value isfalse
.
Monitoring Collection Settings
editThe xpack.monitoring.collection
settings control how data is collected from
your Elasticsearch nodes. You can dynamically change all monitoring collection
settings using the cluster update settings API.
-
xpack.monitoring.collection.enabled
(Dynamic) -
[6.3.0]
Added in 6.3.0.
Set to
true
to enable the collection of monitoring data. When this setting isfalse
(default), Elasticsearch monitoring data is not collected and all monitoring data from other sources such as Kibana, Beats, and Logstash is ignored. -
xpack.monitoring.collection.interval
(Dynamic) -
Setting to
-1
to disable data collection is no longer supported beginning with 7.0.0. [6.3.0] Deprecated in 6.3.0. Usexpack.monitoring.collection.enabled
set tofalse
instead.Controls how often data samples are collected. Defaults to
10s
. If you modify the collection interval, set thexpack.monitoring.min_interval_seconds
option inkibana.yml
to the same value. -
xpack.monitoring.elasticsearch.collection.enabled
(Dynamic) -
Controls whether statistics about your Elasticsearch cluster should be collected. Defaults to
true
. This is different from xpack.monitoring.collection.enabled, which allows you to enable or disable all monitoring collection. However, this setting simply disables the collection of Elasticsearch data while still allowing other data (e.g., Kibana, Logstash, Beats, or APM Server monitoring data) to pass through this cluster. -
xpack.monitoring.collection.cluster.stats.timeout
(Dynamic) -
(time value) Timeout for collecting the cluster statistics. Defaults to
10s
. -
xpack.monitoring.collection.node.stats.timeout
(Dynamic) -
(time value) Timeout for collecting the node statistics. Defaults to
10s
. -
xpack.monitoring.collection.indices
(Dynamic) -
Controls which indices Monitoring collects data from. Defaults to all indices. Specify the index names
as a comma-separated list, for example
test1,test2,test3
. Names can include wildcards, for exampletest*
. You can explicitly exclude indices by prepending-
. For exampletest*,-test3
will monitor all indexes that start withtest
except fortest3
. System indices like .security* or .kibana* always start with a.
, and generally should be monitored. Consider adding.*
to the list of indices ensure monitoring of system indices. For example.*,test*,-test3
-
xpack.monitoring.collection.index.stats.timeout
(Dynamic) -
(time value) Timeout for collecting index statistics. Defaults to
10s
. -
xpack.monitoring.collection.index.recovery.active_only
(Dynamic) -
Controls whether or not all recoveries are collected. Set to
true
to collect only active recoveries. Defaults tofalse
. -
xpack.monitoring.collection.index.recovery.timeout
(Dynamic) -
(time value) Timeout for collecting the recovery information. Defaults to
10s
. -
xpack.monitoring.history.duration
(Dynamic) -
(time value) Retention duration beyond which the indices created by a Monitoring exporter are automatically deleted. Defaults to
7d
(7 days).This setting has a minimum value of
1d
(1 day) to ensure that something is being monitored, and it cannot be disabled.This setting currently only impacts
local
-type exporters. Indices created using thehttp
exporter will not be deleted automatically. -
xpack.monitoring.exporters
- Configures where the agent stores monitoring data. By default, the agent uses a local exporter that indexes monitoring data on the cluster where it is installed. Use an HTTP exporter to send data to a separate monitoring cluster. For more information, see local exporter settings, HTTP exporter settings, and How it works.
Local Exporter Settings
editThe local
exporter is the default exporter used by Monitoring. As the name is
meant to imply, it exports data to the local cluster, which means that there
is not much needed to be configured.
If you do not supply any exporters, then Monitoring will automatically create one for you. If any exporter is provided, then no default is added.
xpack.monitoring.exporters.my_local: type: local
-
type
-
The value for a Local exporter must always be
local
and it is required. -
use_ingest
-
Whether to supply a placeholder pipeline to the cluster and a pipeline processor with
every bulk request. The default value is
true
. If disabled, then it means that it will not use pipelines, which means that a future release cannot automatically upgrade bulk requests to future-proof them. -
cluster_alerts.management.enabled
-
Whether to create cluster alerts for this cluster. The default value is
true
. To use this feature, Watcher must be enabled. If you have a basic license, cluster alerts are not displayed.
HTTP Exporter Settings
editThe following lists settings that can be supplied with the http
exporter.
All settings are shown as what follows the name you select for your exporter:
xpack.monitoring.exporters.my_remote: type: http host: ["host:port", ...]
-
type
-
The value for an HTTP exporter must always be
http
and it is required. -
host
-
Host supports multiple formats, both as an array or as a single value. Supported formats include
hostname
,hostname:port
,http://hostname
http://hostname:port
,https://hostname
, andhttps://hostname:port
. Hosts cannot be assumed. The default scheme is alwayshttp
and the default port is always9200
if not supplied as part of thehost
string.xpack.monitoring.exporters: example1: type: http host: "10.1.2.3" example2: type: http host: ["http://10.1.2.4"] example3: type: http host: ["10.1.2.5", "10.1.2.6"] example4: type: http host: ["https://10.1.2.3:9200"]
-
auth.username
-
The username is required if a
auth.password
is supplied. -
auth.password
-
The password for the
auth.username
. -
connection.timeout
-
(time value) Amount of time that the HTTP connection is supposed to wait for a socket to open for the
request. The default value is
6s
. -
connection.read_timeout
-
(time value) Amount of time that the HTTP connection is supposed to wait for a socket to
send back a response. The default value is
10 * connection.timeout
(60s
if neither are set). -
ssl
- Each HTTP exporter can define its own TLS / SSL settings or inherit them. See the TLS / SSL section below.
-
proxy.base_path
-
The base path to prefix any outgoing request, such as
/base/path
(e.g., bulk requests would then be sent as/base/path/_bulk
). There is no default value. -
headers
-
Optional headers that are added to every request, which can assist with routing requests through proxies.
xpack.monitoring.exporters.my_remote: headers: X-My-Array: [abc, def, xyz] X-My-Header: abc123
Array-based headers are sent
n
times wheren
is the size of the array.Content-Type
andContent-Length
cannot be set. Any headers created by the Monitoring agent will override anything defined here. -
index.name.time_format
-
A mechanism for changing the default date suffix for the, by default, daily Monitoring indices.
The default value is
yyyy.MM.dd
, which is why the indices are created daily. -
use_ingest
-
Whether to supply a placeholder pipeline to the monitoring cluster and a pipeline processor with
every bulk request. The default value is
true
. If disabled, then it means that it will not use pipelines, which means that a future release cannot automatically upgrade bulk requests to future-proof them. -
cluster_alerts.management.enabled
-
Whether to create cluster alerts for this cluster. The default value is
true
. To use this feature, Watcher must be enabled. If you have a basic license, cluster alerts are not displayed. -
cluster_alerts.management.blacklist
-
Prevents the creation of specific cluster alerts. It also removes any applicable watches that already exist in the current cluster.
You can add any of the following watch identifiers to the blacklist:
-
elasticsearch_cluster_status
-
elasticsearch_version_mismatch
-
elasticsearch_nodes
-
kibana_version_mismatch
-
logstash_version_mismatch
-
xpack_license_expiration
For example:
["elasticsearch_version_mismatch","xpack_license_expiration"]
. -

X-Pack monitoring TLS/SSL Key and Trusted Certificate Settings
editThe following settings are used to specify a private key, certificate, and the trusted certificates that should be used when communicating over an SSL/TLS connection. A private key and certificate are optional and would be used if the server requires client authentication for PKI authentication. If none of the settings below are specified, the Default TLS/SSL Settings are used.
PEM Encoded Files
editWhen using PEM encoded files, use the following settings:
-
xpack.monitoring.exporters.$NAME.ssl.key
- Path to a PEM encoded file containing the private key.
-

xpack.monitoring.exporters.$NAME.ssl.certificate
- Path to a PEM encoded file containing the certificate (or certificate chain) that will be presented when requested.
-
xpack.monitoring.exporters.$NAME.ssl.certificate_authorities
- List of paths to the PEM encoded certificate files that should be trusted.
Java Keystore Files
editWhen using Java keystore files (JKS), which contain the private key, certificate and certificates that should be trusted, use the following settings:
-
xpack.monitoring.exporters.$NAME.ssl.keystore.path
- Path to the keystore that holds the private key and certificate.
-
xpack.monitoring.exporters.$NAME.ssl.keystore.password
- Password to the keystore.
-

(Secure) - Password to the keystore.
-
xpack.monitoring.exporters.$NAME.ssl.keystore.key_password
-
Password for the private key in the keystore. Defaults to the
same value as
xpack.monitoring.exporters.$NAME.ssl.keystore.password
. -
xpack.monitoring.exporters.$NAME.ssl.keystore.secure_key_password
(Secure) - Password for the private key in the keystore.
-
xpack.monitoring.exporters.$NAME.ssl.truststore.path
- Path to the truststore file.
-
xpack.monitoring.exporters.$NAME.ssl.truststore.password
- Password to the truststore.
-
xpack.monitoring.exporters.$NAME.ssl.truststore.secure_password
(Secure) - Password to the truststore.
PKCS#12 Files
editElasticsearch can be configured to use PKCS#12 container files (.p12
or .pfx
files)
that contain the private key, certificate and certificates that should be trusted.
PKCS#12 files are configured in the same way as Java Keystore Files:
-
xpack.monitoring.exporters.$NAME.ssl.keystore.path
- Path to the PKCS#12 file that holds the private key and certificate.
-
xpack.monitoring.exporters.$NAME.ssl.keystore.type
-
Set this to
PKCS12
to indicate that the keystore is a PKCS#12 file. -
xpack.monitoring.exporters.$NAME.ssl.keystore.password
- Password to the PKCS#12 file.
-
xpack.monitoring.exporters.$NAME.ssl.keystore.secure_password
(Secure) - Password to the PKCS#12 file.
-
xpack.monitoring.exporters.$NAME.ssl.keystore.key_password
-
Password for the private key stored in the PKCS#12 file.
Defaults to the same value as
xpack.monitoring.exporters.$NAME.ssl.keystore.password
. -
xpack.monitoring.exporters.$NAME.ssl.keystore.secure_key_password
(Secure) - Password for the private key stored in the PKCS#12 file.
-
xpack.monitoring.exporters.$NAME.ssl.truststore.path
- Path to the PKCS#12 file that holds the certificates to be trusted.
-
xpack.monitoring.exporters.$NAME.ssl.truststore.type
-
Set this to
PKCS12
to indicate that the truststore is a PKCS#12 file. -
xpack.monitoring.exporters.$NAME.ssl.truststore.password
- Password to the PKCS#12 file.
-
xpack.monitoring.exporters.$NAME.ssl.truststore.secure_password
(Secure) - Password to the PKCS#12 file.
PKCS#11 Tokens
editElasticsearch can be configured to use a PKCS#11 token that contains the private key, certificate and certificates that should be trusted.
PKCS#11 token require additional configuration on the JVM level and can be enabled via the following settings:
-
xpack.monitoring.exporters.$NAME.keystore.type
-
Set this to
PKCS11
to indicate that the PKCS#11 token should be used as a keystore. -
xpack.monitoring.exporters.$NAME.truststore.type
-
Set this to
PKCS11
to indicate that the PKCS#11 token should be used as a truststore.
When configuring the PKCS#11 token that your JVM is configured to use as
a keystore or a truststore for Elasticsearch, the PIN for the token can be
configured by setting the appropriate value to ssl.truststore.password
or ssl.truststore.secure_password
in the context that you are configuring.
Since there can only be one PKCS#11 token configured, only one keystore and
truststore will be usable for configuration in Elasticsearch. This in turn means
that only one certificate can be used for TLS both in the transport and the
http layer.
