[[monitoring-troubleshooting-no-data]]
|
||
=== No monitoring data is visible in {kib}
|
||
|
||
*Symptoms*:
|
||
There is no information about your cluster on the *Stack Monitoring* page in
|
||
{kib}.
|
||
|
||
*Resolution*:
|
||
Check whether the appropriate indices exist on the monitoring cluster. For
|
||
example, use the <<cat-indices,cat indices>> command to verify that
|
||
there is a `.monitoring-kibana*` index for your {kib} monitoring data and a
|
||
`.monitoring-es*` index for your {es} monitoring data. If you are collecting
|
||
monitoring data by using {metricbeat} the indices have `-mb` in their names. If
|
||
the indices do not exist, review your configuration. For example, see
|
||
<<monitoring-production>>.

[[monitoring-troubleshooting-uuid]]
|
||
=== Monitoring data for some {stack} nodes or instances is missing from {kib}
|
||
|
||
*Symptoms*:
|
||
The *Stack Monitoring* page in {kib} does not show information for some nodes or
|
||
instances in your cluster.
|
||
|
||
*Resolution*:
|
||
Verify that the missing items have unique UUIDs. Each {es} node, {ls} node,
|
||
{kib} instance, Beat instance, and APM Server is considered unique based on its
|
||
persistent UUID, which is found in its `path.data` directory. Alternatively, you
|
||
can find the UUIDs in the product logs at startup.
|
||
|
||
In some cases, you can also retrieve this information via APIs:
|
||
|
||
* For Beat instances, use the HTTP endpoint to retrieve the `uuid` property.
|
||
For example, refer to
|
||
{filebeat-ref}/http-endpoint.html[Configure an HTTP endpoint for {filebeat} metrics].
|
||
* For {kib} instances, use the
|
||
{kibana-ref}/access.html#status[status endpoint] to retrieve the `uuid` property.
|
||
* For {ls} nodes, use the
|
||
{logstash-ref}/monitoring-logstash.html[monitoring APIs root resource] to
|
||
retrieve the `id` property.
|
||
|
||
TIP: When you install {es}, {ls}, {kib}, APM Server, or Beats, their `path.data`
|
||
directory should be non-existent or empty; do not copy this directory from other
|
||
installations.
