今天重啟Kibana容器，結果啟動不了，一看日志發現是Data數據量太大報錯。
FATAL [circuit_breaking_exception] [parent] Data too large, data for [<http_request>] would be [250592200/238.9mb], which is larger than the limit of [246546432/235.1mb], real usage: [250592200/238.9mb], new bytes reserved: [0/0b], usages [request=16512/16.1kb, fielddata=11330/11kb, in_flight_requests=0/0b, accounting=7160235/6.8mb], with { bytes_wanted=250592200 & bytes_limit=246546432 & durability="PERMANENT" } :: {"path":"/.kibana","query":{},"statusCode":429,"response":"{\"error\":{\"root_cause\":[{\"type\":\"circuit_breaking_exception\",\"reason\":\"[parent] Data too large, data for [<http_request>] would be [250592200/238.9mb], which is larger than the limit of [246546432/235.1mb], real usage: [250592200/238.9mb], new bytes reserved: [0/0b], usages [request=16512/16.1kb, fielddata=11330/11kb, in_flight_requests=0/0b, accounting=7160235/6.8mb]\",\"bytes_wanted\":250592200,\"bytes_limit\":246546432,\"durability\":\"PERMANENT\"}],\"type\":\"circuit_breaking_exception\",\"reason\":\"[parent] Data too large, data for [<http_request>] would be [250592200/238.9mb], which is larger than the limit of [246546432/235.1mb], real usage: [250592200/238.9mb], new bytes reserved: [0/0b], usages [request=16512/16.1kb, fielddata=11330/11kb, in_flight_requests=0/0b, accounting=7160235/6.8mb]\",\"bytes_wanted\":250592200,\"bytes_limit\":246546432,\"durability\":\"PERMANENT\"},\"status\":429}"}
數據量太大導致內存不足，可以設置fielddata的內存限制，默認60%
- curl -u elastic -XPUT "ip:port/_cluster/settings" -H 'Content-Type: application/json' -d '{ "persistent" : { "indices.breaker.fielddata.limit" : "40%" } }'
- -u elastic 為elasticsearch的用戶驗證，沒有設置可以不加
