Getting Started with Datadog

I'm seeing this error in the Datadog Agent logs:

Unable to fetch Neo4j stats: 404 Client Error: Not Found for url: http://localhost:7474/db/data/

I've ensured the HTTP connector is enabled and working:

$ curl -i --header "Authorization: Basic ***" http://localhost:7474
HTTP/1.1 200 OK

  "cluster" : "http://localhost:7474/db/{databaseName}/cluster",
  ... snipped private info ...
  "neo4j_version" : "4.0.1",
  "neo4j_edition" : "enterprise"
}

Does the Datadog integration need to be updated to query a different endpoint in 4.0?

Neo4j V4.0.1 after upgrade HTTP endpoint errors

I create 120+ queries in a promise array so was wondering if I am somehow flooding the database. This program worked fine in V3.5 so I will b…

3.5.x had this endpoint:

http://localhost:7474/db/data

4.0.x has this endpoint:

http://localhost:7474/db/{databaseName}
