=== Monitoring settings in Kibana

<titleabbrev>Monitoring settings</titleabbrev>

|
||
|
||
By default, the Monitoring application is enabled, but data collection
|
||
is disabled. When you first start {kib} monitoring, you are prompted to
|
||
enable data collection. If you are using {security}, you must be
|
||
signed in as a user with the `cluster:manage` privilege to enable
|
||
data collection. The built-in `superuser` role has this privilege and the
|
||
built-in `elastic` user has this role.
|
||
|
||
You can adjust how monitoring data is
|
||
collected from {kib} and displayed in {kib} by configuring settings in the
|
||
`kibana.yml` file. There are also `monitoring.ui.elasticsearch.*` settings,
|
||
which support the same values as <<settings,{kib} configuration settings>>.
|
||
|
||
To control how data is collected from your {es} nodes, you configure
|
||
{ref}/monitoring-settings.html[`xpack.monitoring.collection`
|
||
settings] in `elasticsearch.yml`. To control how monitoring data is collected
|
||
from Logstash, configure monitoring settings in `logstash.yml`.
|
||
|
||
For more information, see
|
||
{ref}/monitor-elasticsearch-cluster.html[Monitor a cluster].

==== General monitoring settings
|
||
|
||
[cols="2*<"]
|
||
|===
|
||
| `monitoring.enabled`
|
||
| Set to `true` (default) to enable the {monitor-features} in {kib}. Unlike the
|
||
`monitoring.ui.enabled` setting, when this setting is `false`, the
|
||
monitoring back-end does not run and {kib} stats are not sent to the monitoring
|
||
cluster.
|
||
|
||
| `monitoring.ui.elasticsearch.hosts`
|
||
| Specifies the location of the {es} cluster where your monitoring data is stored.
|
||
By default, this is the same as `elasticsearch.hosts`. This setting enables
|
||
you to use a single {kib} instance to search and visualize data in your
|
||
production cluster as well as monitor data sent to a dedicated monitoring
|
||
cluster.
|
||
|
||
| `monitoring.ui.elasticsearch.username`
|
||
| Specifies the username used by {kib} monitoring to establish a persistent connection
|
||
in {kib} to the {es} monitoring cluster and to verify licensing status on the {es}
|
||
monitoring cluster. +
|
||
+
|
||
Every other request performed by the Stack Monitoring UI to the monitoring {es}
|
||
cluster uses the authenticated user's credentials, which must be the same on
|
||
both the {es} monitoring cluster and the {es} production cluster. +
|
||
+
|
||
If not set, {kib} uses the value of the `elasticsearch.username` setting.
|
||
|
||
| `monitoring.ui.elasticsearch.password`
|
||
| Specifies the password used by {kib} monitoring to establish a persistent connection
|
||
in {kib} to the {es} monitoring cluster and to verify licensing status on the {es}
|
||
monitoring cluster. +
|
||
+
|
||
Every other request performed by the Stack Monitoring UI to the monitoring {es}
|
||
cluster uses the authenticated user's credentials, which must be the same on
|
||
both the {es} monitoring cluster and the {es} production cluster. +
|
||
+
|
||
If not set, {kib} uses the value of the `elasticsearch.password` setting.
|
||
|
||
| `monitoring.ui.elasticsearch.pingTimeout`
|
||
| Specifies the time in milliseconds to wait for {es} to respond to internal
|
||
health checks. By default, it matches the `elasticsearch.pingTimeout` setting,
|
||
which has a default value of `30000`.

==== Monitoring collection settings
|
||
|
||
These settings control how data is collected from {kib}.
|
||
|
||
[cols="2*<"]
|
||
|===
|
||
| `monitoring.kibana.collection.enabled`
|
||
| Set to `true` (default) to enable data collection from the {kib} NodeJS server
|
||
for {kib} Dashboards to be featured in the Monitoring.
|
||
|
||
| `monitoring.kibana.collection.interval`
|
||
| Specifies the number of milliseconds to wait in between data sampling on the
|
||
{kib} NodeJS server for the metrics that are displayed in the {kib} dashboards.
|
||
Defaults to `10000` (10 seconds).

|
||
[[monitoring-ui-settings]]
|
||
==== Monitoring UI settings
|
||
|
||
These settings adjust how the {kib} Monitoring page displays monitoring data.
|
||
However, the defaults work best in most circumstances. For more information
|
||
about configuring {kib}, see
|
||
{kibana-ref}/settings.html[Setting Kibana Server Properties].
|
||
|
||
[cols="2*<"]
|
||
|===
|
||
| `monitoring.ui.elasticsearch.logFetchCount`
|
||
| Specifies the number of log entries to display in the Monitoring UI. Defaults to
|
||
`10`. The maximum value is `50`.
|
||
|
||
| `monitoring.ui.max_bucket_size`
|
||
| Specifies the number of term buckets to return out of the overall terms list when
|
||
performing terms aggregations to retrieve index and node metrics. For more
|
||
information about the `size` parameter, see
|
||
{ref}/search-aggregations-bucket-terms-aggregation.html#search-aggregations-bucket-terms-aggregation-size[Terms Aggregation].
|
||
Defaults to `10000`.
|
||
|
||
| `monitoring.ui.min_interval_seconds`
|
||
| Specifies the minimum number of seconds that a time bucket in a chart can
|
||
represent. Defaults to 10. If you modify the
|
||
`monitoring.ui.collection.interval` in `elasticsearch.yml`, use the same
|
||
value in this setting.
|
||
|
||
| `monitoring.ui.enabled`
|
||
| Set to `false` to hide the Monitoring UI in {kib}. The monitoring back-end
|
||
continues to run as an agent for sending {kib} stats to the monitoring
|
||
cluster. Defaults to `true`.

|
||
===== Monitoring UI container settings
|
||
|
||
The Monitoring UI exposes the Cgroup statistics that we collect for you to make
|
||
better decisions about your container performance, rather than guessing based on
|
||
the overall machine performance. If you are not running your applications in a
|
||
container, then Cgroup statistics are not useful.
|
||
|
||
[cols="2*<"]
|
||
|===
|
||
| `monitoring.ui.container.elasticsearch.enabled`
|
||
| For {es} clusters that are running in containers, this setting changes the
|
||
*Node Listing* to display the CPU utilization based on the reported Cgroup
|
||
statistics. It also adds the calculated Cgroup CPU utilization to the
|
||
*Node Overview* page instead of the overall operating system's CPU
|
||
utilization. Defaults to `false`.
|
||
|
||
| `monitoring.ui.container.logstash.enabled`
|
||
| For {ls} nodes that are running in containers, this setting
|
||
changes the {ls} *Node Listing* to display the CPU utilization
|
||
based on the reported Cgroup statistics. It also adds the
|
||
calculated Cgroup CPU utilization to the {ls} node detail
|
||
pages instead of the overall operating system’s CPU utilization. Defaults to `false`.
