Problem with elastic in grafana

Elastic Stack Elasticsearch
1

Hi guys today I found a problem when adding my elasticsearch to graphana, besides it takes a while to load the reports, several times I get this error message and I need to delete my pod and recreate it, has anyone been there? Can you help?

Error Message:

Elasticsearch error: [parent] Data too large, data for [<http_request>] would be [2283066452/2.1gb], which is larger than the limit of [2282858086/2.1gb], real usage: [2283064856/2.1gb], new bytes reserved: [1596/1.5kb], usages [request=0/0b, fielddata=1474133989/1.3gb, in_flight_requests=1596/1.5kb, accounting=356557840/340mb]

Version: ElasticSearch 7.5

Parent circuit breaker is helping to prevent OOM by preventing the additional memory cost that the http_request would have required. The main cause here is the current usage as opposed to the additional JVM Heap Usage

Mostly here you should either :

You might want to verify if usage is expected GET /_nodes/stats/indices/fielddata?level=shards&pretty=true&fields=* and potentially clear fielddata cache in case that you find document id in there (_id) (from 7.6 this can be disabled)

Thanks Julien, for the reply. I increase more memory to JVM, the problem its not happened still.

I have other question...

My grafana is connected to elasticsearch, but my dashboards are veryyyy slow.

My environment stay with SSD (type GP3 AWS).

I do not know what to do :frowning:

Exists one way to perform this?

Tks

Regards
