如何找到Elastic Search用于索引的磁盘空间量?我目前正在本地运行它,我正在尝试查看我将在虚拟机上需要多少磁盘空间。

Elasticsearch执行此操作的方法是使用_cat/shards
并查看store
列:
curl -XGET "http://localhost:9200/_cat/shards?v"
index shard prirep state docs store ip node

否则在Linux中按文件夹使用来查看空间:
du -hs /myelasticsearch/data/folder
或按文件系统查看空间:
df -h

如果您不需要/_cat/shards
返回的每个分片统计信息,则可以使用
curl -XGET localhost:9200/_cat/allocation?v
为每个节点使用和获得可用磁盘空间。
答案 2 :(得分:13)
你可以使用节点stats rest API
见:https://www.elastic.co/guide/en/elasticsearch/reference/1.6/cluster-nodes-stats.html
请求fs统计信息,如下所示: http://:9200 / _nodes / stats / fs?pretty = 1
你会看到:
{
"cluster_name" : "<cluster>",
"nodes" : {
"pEO34wutR7qk3Ix8N7MgyA" : {
"timestamp" : 1438880525206,
"name" : "<name>",
"transport_address" : "inet[/10.128.37.111:9300]",
"host" : "<host>",
"ip" : [ "inet[/10.128.37.111:9300]", "NONE" ],
"fs" : {
"timestamp" : 1438880525206,
"total" : {
"total_in_bytes" : 363667091456,
"free_in_bytes" : 185081352192,
"available_in_bytes" : 166608117760,
"disk_reads" : 154891,
"disk_writes" : 482628039,
"disk_io_op" : 482782930,
"disk_read_size_in_bytes" : 6070391808,
"disk_write_size_in_bytes" : 1989713248256,
"disk_io_size_in_bytes" : 1995783640064,
"disk_queue" : "0",
"disk_service_time" : "0"
},
"data" : [ {
"path" : "/data1/elasticsearch/data/<cluster>/nodes/0",
"mount" : "/data1",
"dev" : "/dev/sda4",
"total_in_bytes" : 363667091456,
"free_in_bytes" : 185081352192,
"available_in_bytes" : 166608117760,
"disk_reads" : 154891,
"disk_writes" : 482628039,
"disk_io_op" : 482782930,
"disk_read_size_in_bytes" : 6070391808,
"disk_write_size_in_bytes" : 1989713248256,
"disk_io_size_in_bytes" : 1995783640064,
"disk_queue" : "0",
"disk_service_time" : "0"
} ]
}
}
}
}
列出了数据驱动器的空间:
"total" : {
"total_in_bytes" : 363667091456,
"free_in_bytes" : 185081352192,
"available_in_bytes" : 166608117760,

要查看ES群集上的整体磁盘使用/可用空间,可以使用以下命令:
public class browserSetup{
WebDriver driver;
public WebDriver createFirefoxDriver(){
// set path for geckodriver
return new FirefoxDriver();
}
public WebDriver createChromeDriver(){
//set path for chrome driver
return new ChromeDriver();
}
public WebDriver getActiveObject() {
return this.driver;
}
}
希望这有帮助。

查找索引大小的更简洁的解决方案是使用
curl -XGET 'localhost:9200/_cat/indices?v'
输出有一个'store.size'列,可以准确地告诉您索引的大小。
health status index uuid pri rep docs.count docs.deleted store.size pri.store.size

此外,您可以使用
了解可用的磁盘空间curl -XGET 'localhost:9200/_nodes/_local/stats/fs'
在'fs'键下查找磁盘空间信息
{
"_nodes": {
"total": 1,
"successful": 1,
"failed": 0
},
"cluster_name": "elasticsearch",
"nodes": {
"MfgVaoRQT9iRAZtAvO549Q": {
"fs": {
"timestamp": 1488466297268,
"total": {
"total_in_bytes": 29475753984,
"free_in_bytes": 18352095232,
"available_in_bytes": 18352095232
},
}
}
}
}
我已经针对ElasticSearch版本5.2.1进行了测试

您可能希望将_cat api用于节点式磁盘空间使用
curl http://host:9200/_cat/nodes?h=h,diskAvail
参考:https://www.elastic.co/guide/en/elasticsearch/reference/current/cat-nodes.html

运行以下命令来查找每个弹性搜索索引所使用的磁盘空间
# FOR SHARDS
curl http://host:9200/_cat/shards?v&pretty
# OR
GET _cat/shards?v&pretty
运行以下命令来查找每个弹性搜索索引所使用的磁盘空间
# FOR INDICES
curl -XGET 'host:9200/_cat/indices?v&pretty
# SORT BY SIZE STORE OF INDICES
curl -XGET 'host:9200/_cat/indices/_all?v&s=store.size
输出
# GET /_cat/indices/_all?v&s=store.size

或者您也可以直接查询磁盘以测量Elasticsearch节点上/ var / lib / elasticsearch / [environment name] / nodes / 0 / indices下的每个目录的磁盘空间。
$ du -b --max-depth=1 /var/lib/elasticsearch/[environment name]/nodes/0/indices | sort -rn | numfmt --to=iec --suffix=B --padding=5
17GB / var / lib / elasticsearch / env1 / nodes / 0 / indices 3.8GB / var / lib / elasticsearch / env1 / nodes / 0 / indices / index1 2.1GB / var / lib / elasticsearch / env1 / nodes / 0 / indices / index2 1.2GB ......
