Might be some other issue related to loading plots from elastic. Can you show the trains-apiserver log again after you received the error - there should be some more information there
Ok , i will start a new experiment to see if the error will be still there? Sorry i dont really get how to show the trains-apiserver log
The error is still there for new experiment
SubstantialBaldeagle49 This should collect the logs: 'sudo docker logs trains-apiserver >& apiserver.logs'
SuccessfulKoala55 AppetizingMouse58 I delete logs/apiserver.log, and restart the server , and here is the log. It show cannot connect to ElasticSearch
SubstantialBaldeagle49 The log looks OK. Where do you see the error?
SubstantialBaldeagle49 This is fine. When you start docker-compose it takes different time for the services to start. Apiserver waits for the Elasticsearch to start and proceeds once it is ready. Can you reproduce the buckets issue and share the apiserver log that contains it?
AppetizingMouse58 Ok, this is the full log, here seems a error:
AppetizingMouse58 After i modify the max_buckets to 200000000000, I cannot see any information in web ui. Here is the log:
SubstantialBaldeagle49 Well, I see. Elaticsearch does not support putting that large number into max_buckets. From the error message that I see in the apiserver log I am not sure that the original problem is connected to the buckets number. Can you please revert the max_bucket change, reproduce the original problem and share the elasticsearch log?
Ok, i have reverte the change ,here is two log:
The log is produced after i go to the web ui and reproduce the error of "Failed to get Plot Charts"

How to set the timeout?
What can be seen in the logs is that for some reason Elasticsearch had internal failure when trying to perform the plots query. I will send you the instruction on how to check for the health of ES nodes. It may provide us with some clues
Please run these commands and see if you have any "red" statuses in the output:
curl " http://localhost:9200/_cluster/health?pretty "
curl " http://localhost:9200/_cluster/health?level=indices&pretty "
I have remake curl, this commad "sudo curl -L " https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compos" will work
The index "events-plot-d1bd92a3b039400cbafc60a7a5b1e52b" is red meaning that it is corrupted and elastic cannot work with it. The most straightforward solution would be to delete this index but it will result in all the plots generated so far will be lost.
That's ok, i have just start the server. Could you tell me how to delete this index?
Sure, you delete it with the following command:
curl -XDELETE " http://localhost:9200/events-plot-d1bd92a3b039400cbafc60a7a5b1e52b "
Once deleted it will be automatically recreated by the api server and should see the plots from the new tasks that you run afterwards
AppetizingMouse58 Thanks so much!, Could u tell why does this happen? If it happen next time , is there any other solution?
