=== Rendering pre-captured profiler JSON
|
|
|
|
The Search Profiler queries the cluster that the Kibana node is attached to.
|
|
It does this by executing the query against the cluster and collecting the results.
|
|
|
|
This is convenient, but sometimes performance problems are temporal in nature. For example,
|
|
a query might only be slow at certain time of day when many customers are using your system.
|
|
You can setup a process to automatically profile slow queries when they occur and then
|
|
save those profile responses for later analysis.
|
|
|
|
The Search Profiler supports this workflow by enabling you to paste the
|
|
pre-captured JSON. The tool will detect that this is a profiler response JSON
|
|
rather than a query, and render the visualization rather than querying the cluster.
|
|
|
|
To see how this works, copy and paste the following profile response into the
|
|
query editor and click *Profile*:
