Debugging Tools in mev-commit execution client

As the mev-commit execution client is under active development, it includes debugging tools for in-depth analysis. These tools, primarily intended for developers and not for everyday users, offer insights into the node's functionality. They are accessible via the HTTP API endpoint.

Understanding Network Topology

You can view the network's topology as recognized by the mev-commit execution client at the /topology endpoint. This provides information such as the number of connected nodes and their roles, helping to ensure your node is well-connected within the network.

Example of Topology Data:

  "self": {
    "Addresses": [
    "Ethereum Address": "0xB8c29FfD307067471fd7997873DfC496Fd02956f",
    "Peer Type": "bootnode",
    "Underlay": "16Uiu2HAmLYUvthfDCewNMdfPhrVefBbsfaPL22fWWfC2zuoh5SpV"
  "connected_peers": {
    "bidders": [
  "blocked_peers": [
      "Peer": "0x48ddc642514370bdafad81c91e23759b0302c915",
      "Reason": "insufficient stake",
      "Duration": "1m58.244219375s"

Prometheus Metrics for Monitoring

The node emits various Prometheus metrics, which can be utilized to create dashboards displaying the node's statistics. These include default metrics from the libp2p networking library and are available at the /metrics endpoint.

Pprof Endpoints

For advanced users, pprof endpoints are available at /debug/pprof for performance profiling, such as monitoring memory and CPU usage. However, understanding and using these endpoints requires prior knowledge of pprof tools and is not covered in this documentation.
