ES 分片爆滿

ES報錯：
Validation Failed: 1: this action would add [1] total shards, but this cluster currently has [2000]/[2000] maximum shards open;
[es01] unexpected error while indexing monitoring document

原因：ES集羣默認有最大分片數2000的限制，達到最大數以後，無法添加新的分片，導致無法創建索引寫入日誌。

解決：在kibana上的DEV TOOL工具裏執行如下命令。

PUT /_cluster/settings
{
  "transient": {
    "cluster": {
      "max_shards_per_node":12000
    }
  }
}
