You can drill down into the status of your {es} cluster in {kib} by clicking
|
|
the <<cluster-overview-page, Overview>>, <<nodes-page, Nodes>>, and
|
|
<<indices-overview-page, Indices>> links on the *Monitoring* page.
|
|
|
|

==== Cluster Overview
|
|
|
|
To view the key metrics that indicate the overall health of an {es} cluster,
|
|
click **Overview** in the {es} section. Anything that needs your attention is
|
|
highlighted in yellow or red.
|
|
|
|
TIP: Conditions that require your attention are listed at the top of the
|
|
Clusters page. You can also set up watches to alert you when the status
|
|
of your cluster changes. To learn how, see
|
|
{xpack-ref}/watch-cluster-status.html[Watch Your Cluster Health].
|
|
|
|
The panel at the top shows the current cluster statistics, the charts show the
|
|
search and indexing performance over time, and the table at the bottom shows
|
|
information about any shards that are being recovered.

|
|
|
|
TIP: Not sure what a chart is showing? Click the info button for a description
|
|
of the metrics.
|
|
|
|
From there, you can dive into detailed metrics for particular nodes and indices.

|
|
==== Nodes
|
|
|
|
To view node metrics, click **Nodes**. The Nodes section shows the status
|
|
of each node in your cluster.

|
|
===== Node Overview
|
|
|
|
Click the name of a node to view its node statistics over time. These represent
|
|
high-level statistics collected from {es} that provide a good overview of health.

[[nodes-page-advanced]]
|
|
===== Node Advanced
|
|
|
|
To view advanced node metrics, click the **Advanced** tab for a node. The
|
|
*Advanced* tab shows additional metrics, such as memory and garbage collection
|
|
statistics reported by the selected {es} node.
|
|
|
|
image::monitoring/images/monitoring-node-advanced.png["Elasticsearch Node Advanced",link="images/monitoring-node-advanced.png"]
|
|
|
|
You can use the advanced node view to diagnose issues that generally involve
|
|
more advanced knowledge of {es}, such as poor garbage collection performance.

|
|
[[indices-overview-page]]
|
|
==== Indices
|
|
|
|
To view index metrics, click **Indices**. The Indices section shows the same
|
|
overall index and search metrics as the Overview and a table of your indices.
|
|
|
|

[[indices-page-overview]]
|
|
===== Index Overview
|
|
|
|
From the Indices listing, you can view data for a particular index. To drill
|
|
down into the data for a particular index, click its name in the Indices table.
|
|
|
|

|
|
[[indices-page-advanced]]
|
|
===== Index Advanced
|
|
|
|
To view advanced index metrics, click the **Advanced** tab for an index. The
|
|
*Advanced* tab shows additional metrics, such as memory statistics reported
|
|
about the {es} index. If the index has more than one shard, then its shards
|
|
might live on more than one node.
|
|
|
|
image::monitoring/images/monitoring-index-advanced.png["Elasticsearch Index Advanced",link="images/monitoring-index-advanced.png"]
|
|
|
|
The Advanced index view can be used to diagnose issues that generally involve
|
|
more advanced knowledge of {es}, such as wasteful index memory usage.
