OpenBlockperf
A CLI tool and systemd service that captures and shares network metrics from a Cardano relay node.
The client collects selected tracer and peering data from a local relay so stake pool operators can contribute to a shared view of block propagation and connectivity. It is intended for relay nodes that sit between a stake pool producer and the rest of the network. Running it on a producer is possible but not recommended. In normal operation it runs as a systemd service.

Installation
You can install the package from PyPI:
pip install openblockperf
A plain pip install only provides the blockperf command. It does not
discover your cardano-node unit, write config.json, or install the systemd
service.
The recommended way on a Linux relay is the installer script. It installs the PyPI package into a dedicated virtualenv and wires it into the existing node installation and network configuration (systemd unit, config file, service user, and CLI wrapper):
curl -fsSL https://raw.githubusercontent.com/cardano-foundation/openblockperf/main/blockperf-install.sh -o blockperf-install.sh
chmod +x blockperf-install.sh
sudo ./blockperf-install.sh
