The *Stack Monitoring > Clusters* page in {kib} summarizes the status of your
|
||||
{stack}. You can drill down into the metrics to view more information about your
|
||||
cluster and specific nodes, instances, and indices.
|
||||
|
||||
The Top Cluster Alerts shown on the Clusters page notify you of
|
||||
conditions that require your attention:
|
||||
|
||||
* {es} Cluster Health Status is Yellow (missing at least one replica)
|
||||
or Red (missing at least one primary).
|
||||
* {es} Version Mismatch. You have {es} nodes with
|
||||
different versions in the same cluster.
|
||||
* {kib} Version Mismatch. You have {kib} instances with different
|
||||
versions running against the same {es} cluster.
|
||||
* Logstash Version Mismatch. You have Logstash nodes with different
|
||||
versions reporting stats to the same monitoring cluster.
|
||||
* {es} Nodes Changed. You have {es} nodes that were recently added or removed.
|
||||
* {es} License Expiration. The cluster's license is about to expire.
|
||||
+
|
||||
--
|
||||
If you do not preserve the data directory when upgrading a {kib} or
|
||||
Logstash node, the instance is assigned a new persistent UUID and shows up
|
||||
as a new instance
|
||||
--
|
||||
* {xpack} License Expiration. When the {xpack} license expiration date
|
||||
approaches, you will get notifications with a severity level relative to how
|
||||
soon the expiration date is:
|
||||
** 60 days: Informational alert
|
||||
** 30 days: Low-level alert
|
||||
** 15 days: Medium-level alert
|
||||
** 7 days: Severe-level alert
|
||||
+
|
||||
The 60-day and 30-day thresholds are skipped for Trial licenses, which are only
|
||||
valid for 30 days.
|
||||
|
||||
The {monitor-features} check the cluster alert conditions every minute. Cluster
|
||||
alerts are automatically dismissed when the condition is resolved.
|
||||
|
||||
NOTE: {watcher} must be enabled to view cluster alerts. If you have a Basic
|
||||
license, Top Cluster Alerts are not displayed.

[[cluster-alert-email-notifications]]
|
||||
== Email Notifications
|
||||
To receive email notifications for the Cluster Alerts:
|
||||
|
||||
1. Configure an email account as described in
|
||||
{ref}/actions-email.html#configuring-email[Configuring email accounts].
|
||||
2. Configure the
|
||||
`monitoring.cluster_alerts.email_notifications.email_address` setting in
|
||||
`kibana.yml` with your email address.
|
||||
+
|
||||
--
|
||||
TIP: If you have separate production and monitoring clusters and separate {kib}
|
||||
instances for those clusters, you must put the
|
||||
`monitoring.cluster_alerts.email_notifications.email_address` setting in
|
||||
the {kib} instance that is associated with the production cluster.
|
||||
|
||||
--
|
||||
|
||||
Email notifications are sent only when Cluster Alerts are triggered and resolved.
