How can I delete a large number of flow sources?

There is no batch delete option in the GUI but it is possible to use REST API to do batch operations.

Example of deleting flow sources via SSH with curl:

1. Obtain an access token

   curl https://localhost/resources/oauth/token -k -d grant_type=password -d client_id=invea-tech -d username=admin -d password=admin

   Replace username and password fields with your desired GUI user details.
   Sample response:

   {
   "access_token":"e6a7b08c56326685a56c572718e02db33ae1363e9104d93baaa790de8eab0dc1",
   "expires_in":86400,
   "token_type":"bearer",
   "refresh_token":"998adfa95793197eca0b1118efd736cbf410c7ffe753d1067d0d36e37da0c17e"
   }

2. List all flow sources

   curl -G -k https://localhost/rest/fmc/sources?interfaces=false -H "Authorization: bearer <access_token>"

   Replace <access_token> with the token obtained in step 1.
   The request returns JSON with all flow sources (ID, IP, name,...).
   Sample response:

   [{
   "id":124,
   "ip":"127.0.0.1",
   "name":"127.0.0.1 (localhost, NetFlow-port2055)",
   "hostname":"localhost",
   "internalId":"127.0.0.1|p2055|0"
   }]

3. Delete desired IDs
   

   curl -X DELETE -k https://localhost/rest/fmc/sources/<ID1>  -H "Authorization: bearer <access_token>"
   curl -X DELETE -k https://localhost/rest/fmc/sources/<ID2>  -H "Authorization: bearer <access_token>"
   ...

   Replace <ID> with the ID obtained in step 2 and <access_token> with the token obtained in step 1.
