=== cat recovery API
++++
cat recovery
++++
Returns information about ongoing and completed shard recoveries,
similar to the <> API.
For data streams, the API returns information about the stream's backing
indices.
[[cat-recovery-api-request]]
==== {api-request-title}
`GET /_cat/recovery/`
`GET /_cat/recovery`
[[cat-recovery-api-desc]]
==== {api-description-title}
The cat recovery API returns information about shard recoveries, both
ongoing and completed. It is a more compact view of the JSON
<> API.

[[cat-recovery-path-params]]
==== {api-path-parms-title}
``::
(Optional, string)
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
my-index-000001 0 13ms store done n/a n/a 127.0.0.1 node-0 n/a n/a 0 0 100% 13 0 0 100% 9928 0 0 100.0%
---------------------------------------------------------------------------
// TESTRESPONSE[s/store/empty_store/]
// TESTRESPONSE[s/100%/0.0%/]
// TESTRESPONSE[s/9928/0/]
// 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 <> 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%
--------------------------------------------------------------------------------
