@lzukel
Can you provide the signal json file (the checks section)?

There is no checks section.
There are no watches.

Does this happen on a fresh installation? Or did this work for you before and has now ceased to work?

Does Kibana directly connect to Elasticsearch? Or is there a proxy, loadbalancer or similar thing between Kibana and ES?
