["Peeyush Bishnoi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FALCON-1643?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15044989#comment-15044989 ] 

Peeyush Bishnoi commented on FALCON-1643:
-----------------------------------------

To display the replication metrics through CLI,  API is required to fetch the required metrics from the Falcon instances vertices stored in GraphDB. 

{code:java}
GET http://host/metadata/discovery/$type/list?entity_name=$entity_name&limit=$limit

$type is 'metrics' and it will be defined RelationshipType.
$entity_name is name of the feed/process entity. 
$limit is number of instances.

Note: Recipe create the process entity to replicate the data from source to destination.

Example:
Fetch 10 Falcon instances replication metrics for entity name hdfs-replication :
GET http://host/graphs/lineage/metrics/list?entity_name=hdfs-replication&limit=10
{code}

If limit attribute is not defined by default, API will fetch the metrics for 5 instances.
