In this initial demo setup, we should connect an immdb-server to a cardano-node as its downstream peer, which is itself connected to another cardano-node as its downstream peer.

graph LR
    A[immdb-server] --> B[cardano-node 0]
    B[cardano-node 0] --> C[cardano-node 1]

The demo run terminates after the immdb-server has served all the blocks in the given ChainDB.

For this setup, we should develop a script that, given a URL (possible a file path) pointing to the benchmarking cluster run data, executes the processes described above until termination.

Next steps

After this demo setup is ready, the following steps are recommended:

• Modify immdb-server to log the events we want to measure
• Parse the logs and output the information to a file or standard output
• Generate plots using the parsed output

Remember that for the primary measurement, we need to know:

• When the upstream peer sent MsgRollForward to the node-under-test.
• When the downstream peer received the corresponding block from the node-under-test.
