UI Performance
Core UI performance is affected by the overall performance of the other parts of the system. For example, dashboard performance will be impacted by query performance.
Some points for consideration are:
-
Make sure
httponlynodes are sufficiently resourced. These nodes are responsible for servicing the UI, the web API, parsing, and ingest listeners. - Search performance affects the responsiveness of the UI - slow queries result in delayed response in the UI. Make sure digest nodes are sufficiently resourced. For example, if you're doing queries that involve lookup files, or aggregation calculations, make sure you have sufficient RAM, as these query types are memory intensive.
