In my current setup, i have 2 CPU-s, 8GB RAM, no cluster.
I have installed hearthbeat packet, to monitor the system performance of my Elastic stack, but when i try to load dashboard i get an error:
The request for this panel failed.
rejected execution of org.elasticsearch.action.search.FetchSearchPhase$1@45a37a3a on EsThreadPoolExecutor[search, queue capacity = 1000, org.elasticsearch.common.util.concurrent.EsThreadPoolExecutor@487441d4[Running, pool size = 4, active threads = 4, queued tasks = 1233, completed tasks = 793949]]
Does this error occur, simply cause my machine is under provisioned?
Is there a way to enlarge queue capacity, or time needed to get all the data?
Or any other way to fix this problem, without provisioning more hardware?
Thanks in advance.
