Get shard recovery information

GET /_cat/recovery

Get information about ongoing and completed shard recoveries. Shard recovery is the process of initializing a shard copy, such as restoring a primary shard from a snapshot or syncing a replica shard from a primary shard. When a shard recovery completes, the recovered shard is available for search and indexing. For data streams, the API returns information about the stream’s backing indices. IMPORTANT: cat APIs are only intended for human consumption using the command line or Kibana console. They are not intended for use by applications. For application consumption, use the index recovery API.

Query parameters

active_only boolean

If true, the response only includes ongoing shard recoveries.
bytes string

The unit used to display byte values.

Values are b, kb, mb, gb, tb, or pb.
detailed boolean

If true, the response includes detailed information about shard recoveries.
index string | array[string]

Comma-separated list or wildcard expression of index names to limit the returned information
h string | array[string]

List of columns to appear in the response. Supports simple wildcards.
s string | array[string]

List of columns that determine how the table should be sorted. Sorting defaults to ascending and can be changed by setting :asc or :desc as a suffix to the column name.
time string

Unit used to display time values.

Values are nanos, micros, ms, s, m, h, or d.

- index string
- shard string
  
  The shard name.
- start_time string | number
  
  A date and time, either as a string whose format can depend on the context (defaulting to ISO 8601), or a number of milliseconds since the Epoch. Elasticsearch accepts both as input, but will generally output a string representation.

  _types:DateTime string _types:UnitMillis number
  
  Time unit for milliseconds
- start_time_millis number
  
  Time unit for milliseconds

Response examples (200)

A successful response from `GET _cat/recovery?v=true&format=json`. In this example, the source and target nodes are the same because the recovery type is `store`, meaning they were read from local storage on node start.

A successful response from `GET _cat/recovery?v=true&h=i,s,t,ty,st,shost,thost,f,fp,b,bp&format=json`. You can retrieve information about an ongoing recovery for example when you increase the replica count of an index and bring another node online to host the replicas. In this example, the recovery type is `peer`, meaning the shard recovered from another node. The `files` and `bytes` are real-time measurements.

A successful response from `GET _cat/recovery?v=true&h=i,s,t,ty,st,rep,snap,f,fp,b,bp&format=json`. You can restore backups of an index using the snapshot and restore API. You can use the cat recovery API to get information about a snapshot recovery.
