HTTP API

The HTTP API is exposed by the daemon on the IP address and port of the metrics.prometheus configuration setting.

The HTTP API does not support user authentication or HTTPS. Applications will want to firewall this port or bind to a loopback address.

In addition to the common HTTP API, the daemon supports the following API calls:

  • /topology (EXPERIMENTAL)
    • Method GET. Prints a JSON representation of current topology state, displayed in a format that is similar to the topology file. Note that there are slight differences between the output format and the topology file format, which means the output cannot be copy/pasted and used as a topology file.
