Unable to bulk upload the stats payload to the local cluster Kibana 7.3

Elastic Stack Kibana
1

Hey there,

Kibana 7.3

I recieve this message when attempting to bulk :

"tags":["warning","monitoring","kibana-monitoring"],"pid":1,"message":"Unable to bulk upload the stats payload to the local cluster"}

Note that I am testing my elastic stack by generating lots of documents every hour.

Hi @Mohamad-Sobhie

Could you please describe how you are "generating lots of documents"? Just by guessing from the error you're seeing, I am wondering if you are creating many indices and, in turn, many primary shards.

If you go to the "Overview" page in Stack Monitoring for your Elasticsearch cluster, you should see toward the top a bar with metrics, which shows "Total Shards", "Unassigned Shards", and "Total Documents". What are those values?

Best,

-Mike

yes I am creating indices (not sure how many indices is many). Here is my overview

You should aim to keep the number of shards per node as low as possible for the expected load.

There is a good introduction to designing for scale which can be found here: https://www.elastic.co/guide/en/elasticsearch/guide/2.x/scale.html

I might also recommend this webinar on quantitative sizing which should help you to better understand how to test and size an Elasticsearch cluster: https://www.elastic.co/elasticon/conf/2016/sf/quantitative-cluster-sizing
