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?
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
Exists one way to perform this?
