This section describes the Neo4j Usage Data Collector.
The Neo4j Usage Data Collector, UDC, is a sub-system that gathers usage data, reporting it to the UDC-server at udc.neo4j.org. It is easy to disable, and does not collect any data that is confidential. For more information about what is being sent, see below.
The Neo4j team uses this information as a form of automatic, effortless feedback from the Neo4j community. We want to verify that we are doing the right thing by matching download statistics with usage statistics. After each release, we can see if there is a larger retention span of the server software.
The data collected is described in the section below. If any future versions of this system collect additional data, we will clearly announce those changes.
The Neo4j team is very concerned about your privacy. We do not disclose any personally identifiable information.
To gather good statistics about Neo4j usage, UDC collects this information:
After startup, UDC waits for ten minutes before sending the first ping. It does this for two reasons; first, we don’t want the startup to be slower because of UDC, and secondly, we want to keep pings from automatic tests to a minimum. The ping to the UDC servers is done with a HTTP GET.
UDC is disabled by setting
dbms.udc.enabled=false in neo4j.conf.
For more information on where to find the neo4j.conf file, see Section 3.1, “File locations”.
