|
Returns information about ongoing and completed shard recoveries,
|
|
similar to the <<indices-recovery, index recovery>> API.
|
|
|
|
For data streams, the API returns information about the stream's backing
|
|
indices.

|
|
The cat recovery API returns information about shard recoveries, both
|
|
ongoing and completed. It is a more compact view of the JSON
|
|
<<indices-recovery,index recovery>> API.

`<target>`::

Comma-separated list of data streams, indices, and index aliases used to limit

the request. Wildcard expressions (`*`) are supported.

|
To target all data streams and indices in a cluster, omit this parameter or use
|
|
`_all` or `*`.

===== Example with no ongoing recoveries
|
|
|
|
[source,console]
|
|
----------------------------------------------------------------------------
|
|
GET _cat/recovery?v
|
|
----------------------------------------------------------------------------
|
|
// TEST[setup:my_index]
|
|
|
|
The API returns the following response:
|
|
|
|
[source,txt]
|
|
---------------------------------------------------------------------------
|
|
index shard time type stage source_host source_node target_host target_node repository snapshot files files_recovered files_percent files_total bytes bytes_recovered bytes_percent bytes_total translog_ops translog_ops_recovered translog_ops_percent

|
|
// TESTRESPONSE[s/13ms/[0-9.]+m?s/]
|
|
// TESTRESPONSE[s/13/\\d+/ non_json]
|
|
|
|
In this example response, the source and target nodes are the same because the
|
|
recovery type is `store`, meaning they were read from local storage on node
|
|
start.
|
|
|
|
[[cat-recovery-api-ex-live]]
|
|
===== Example with a live shard recovery
|
|
|
|
By increasing the replica count of an index and bringing another node online to
|
|
host the replicas, you can retrieve information about an ongoing recovery.
|
|
|
|
[source,console]
|
|
----------------------------------------------------------------------------
|
|
GET _cat/recovery?v&h=i,s,t,ty,st,shost,thost,f,fp,b,bp
|
|
----------------------------------------------------------------------------
|
|
// TEST[setup:my_index]
|
|
|
|
The API returns the following response:
|
|
|
|
[source,txt]
|
|
----------------------------------------------------------------------------
|
|
i s t ty st shost thost f fp b bp
|
|
my-index-000001 0 1252ms peer done 192.168.1.1 192.168.1.2 0 100.0% 0 100.0%
|
|
----------------------------------------------------------------------------
|
|
// TESTRESPONSE[s/peer/empty_store/]
|
|
// TESTRESPONSE[s/192.168.1.2/127.0.0.1/]
|
|
// TESTRESPONSE[s/192.168.1.1/n\/a/]
|
|
// TESTRESPONSE[s/100.0%/0.0%/]
|
|
// TESTRESPONSE[s/1252ms/[0-9.]+m?s/ non_json]
|
|
|
|
In this example response, the recovery type is `peer`, meaning the shard
|
|
recovered from another node. The returned files and bytes are real-time
|
|
measurements.
|
|
|
|
[[cat-recovery-api-ex-snapshot]]
|
|
===== Example with a snapshot recovery
|
|
|
|
You can restore backups of an index using the <<modules-snapshots,snapshot and
|
|
restore>> API. You can use the cat recovery API retrieve information about a
|
|
snapshot recovery.
|
|
|
|
[source,console]
|
|
--------------------------------------------------------------------------------
|
|
GET _cat/recovery?v&h=i,s,t,ty,st,rep,snap,f,fp,b,bp
|
|
--------------------------------------------------------------------------------
|
|
// TEST[skip:no need to execute snapshot/restore here]
|
|
|
|
The API returns the following response with a recovery type of `snapshot`:
|
|
|
|
[source,txt]
|
|
--------------------------------------------------------------------------------
|
|
i s t ty st rep snap f fp b bp
|
|
my-index-000001 0 1978ms snapshot done my-repo snap_1 79 8.0% 12086 9.0%
