- Please follow steps mentioned in below link in order to get the list of provenance event id's :

Nifi- how to get provenance event id in nifi?

- In order to get more information about a specific event :

For Nifi running in Standalone mode :

# curl -i -X GET http://<hostname>:9090/nifi-api/provenance-events/id

For Nifi running in clustered mode:

# curl -i -X GET http://<hostname>:9090/nifi-api/provenance-events/id?clusterNodeId=<NODE UUID>

There may be multiple events with the same event id(one on each node), so you need to specify from which node you want to return that specific event.

    thanks @amankumbare

    could you please add how you would access the API in a secure NiFi environment - getting a token first, then use the token to access the provenance events.

    Here u go

    Open bash script and put the info

     

    url="https://<you environment>:9091/nifi-api/"
    url_encoded="application/x-www-form-urlencoded"
    accept_header="Accept: application/json"
    content_type="Content-Type: application/json"
    data="username=<your user name>&password=<your password"

    rm -rf /tmp/a

    end_point="access/token"
    curl -k -X POST "${url}${end_point}" -H "${url_encoded}" --data "${data}" > /tmp/a
    token=`cat /tmp/a`
    bearer="Authorization: Bearer ${token}"
     
    # Now you are all set to run the curl commands
     
    # Get root id
    end_point="process-groups/root"
    curl -k -X GET "${url}${end_point}" -H "${content_type}" -H "${bearer}"
     
    # Get all the components under root which includes all processgroups, process, controller service, connections and everything.   
    # NOTE: the identifier id WILL NOT MATCH your NIFI id.  They are different.  but this is one stop for full automation
    end_point="process-groups/root/download"
    curl -k -X GET "${url}${end_point}" -H "${content_type}" -H "${bearer}"
