I have an elasticsearch index (150kb only) which I want to visualise in kibana. After going to stack management > index patterns > crate new index pattern a 429 (Too many requests) error is being thrown. This is from the browser:
Failed to load resource: http://localhost:5601/api/saved_objects/index-pattern the server responded with a status of 429 (Too Many Requests)
Why is this happening? I switched off elasticsearch and kibana and back on but the error persists.
The problem here is that kibana does not really give a good error response. My issue was that elasticsearch was not allowing any changes to be made because it determined that I was running low on storage.
This answer solved the above issue.
In our case we had almost no space left on the disks.
Our solution was to go into Stack Management > Index Management > Select a few indices we no longer needed (eg. old or big), and select manage index, and delete. Afterwards the ES cluster recovered.
