本API用于分析、统计指定index
当前占用的存储空间。
考虑到本特性目前仍然处于预览状态,因此使用方法、参数等可能会发生变化,或者未来也许会被删除。
本API暂时不建议在生产系统中使用。
命令样例如下:
curl -X POST "https://localhost:9200/testindex_001/_disk_usage?run_expensive_tasks=true&pretty" --cacert $ES_HOME/config/certs/http_ca.crt -u "elastic:ohCxPH=QBE+s5=*lo7F9"
执行结果的样例,如下:
{
"_shards" : {
"total" : 1,
"successful" : 1,
"failed" : 0
},
"testindex_001" : {
"store_size" : "249b",
"store_size_in_bytes" : 249,
"all_fields" : {
"total" : "0b",
"total_in_bytes" : 0,
"inverted_index" : {
"total" : "0b",
"total_in_bytes" : 0
},
"stored_fields" : "0b",
"stored_fields_in_bytes" : 0,
"doc_values" : "0b",
"doc_values_in_bytes" : 0,
"points" : "0b",
"points_in_bytes" : 0,
"norms" : "0b",
"norms_in_bytes" : 0,
"term_vectors" : "0b",
"term_vectors_in_bytes" : 0,
"knn_vectors" : "0b",
"knn_vectors_in_bytes" : 0
},
"fields" : { }
}
}
方法参数
ignore_unavailable
,默认值为false
。
true
,本操作执行时跳过失效或者不可用的index
。false
,本操作执行时,遇到失效或者不可用的index
,则报错,样例如下:{ "error" : { "root_cause" : [ { "type" : "index_not_found_exception", "reason" : "no such index [testindex_002]", "resource.type" : "index_or_alias", "resource.id" : "testindex_002", "index_uuid" : "_na_", "index" : "testindex_002" } ], "type" : "index_not_found_exception", "reason" : "no such index [testindex_002]", "resource.type" : "index_or_alias", "resource.id" : "testindex_002", "index_uuid" : "_na_", "index" : "testindex_002" }, "status" : 404 }
wait_for_active_shards
,默认值为1,即主副本。
执行本操作时,必须处于可用状态的副本的数量。
run_expensive_tasks
,默认值为false
。
计算空间占用率的操作需要消耗大量的资源。
true
,执行运算操作。false
,提示错误,样例如下:{ "error" : { "root_cause" : [ { "type" : "illegal_argument_exception", "reason" : "analyzing the disk usage of an index is expensive and resource-intensive, the parameter [run_expensive_tasks] must be set to [true] in order for the task to be performed." } ], "type" : "illegal_argument_exception", "reason" : "analyzing the disk usage of an index is expensive and resource-intensive, the parameter [run_expensive_tasks] must be set to [true] in order for the task to be performed." }, "status" : 400 }
