Filecoin Network Metrics on https://probelab.io

[yiannisbot]

With generous support from the Filecoin Foundation, the ProbeLab team has developed and is maintaining tooling to monitor critical metrics for the Filecoin network. This issue is a summary of the dashboards we maintain. It does not include highlights or items that need attention, partially because there aren't any 🚀 In case of issues that require attention, we will start a different discussion thread in this space and/or in slack.

Filecoin Network Health Weekly Reports

These are published weekly on Monday and include a number of critical metrics on Network Size, Stability & Demographics. The latest report for Week 20, 2025 can be found at: https://probelab.io/filecoin/dht/2025-20/. A blogpost with more details can be found here: https://www.probelab.network/blog/filecoin-network-health-weekly-reports

Filecoin DHT Key Density Monitoring

This set of plots, which can be found here: https://probelab.io/filecoin/keydensity/ present a 7-day rolling window of the DHT's Keyspace Density. This is a critical metric that can detect potential eclipse attacks on the DHT.

Filecoin Network Bootstrapper Uptime Monitoring

As the name suggests, we have set up monitors to capture the liveness of the network's 6 bootstrappers. The dashboard can be found at: https://probelab.io/filecoin/bootstrappers/

Gossipsub Tracing through Hermes

Last, but not least, we have adapted Hermes, a GossipSub listener and tracer, which subscribes to all relevant pubsub topics and traces all protocol interactions, for the Filecoin network. A comprehensive description of how this works can be found in this GH issue: probe-lab/hermes#63.

ProbeLab Tools & Contact

The tools used to produce the above metrics and dashboards are described in detail at: https://probelab.io/tools/. Reach out through this thread, in FIL slack (#probe-lab channel, or DM), or via email if you have feedback or want to see more metrics for Filecoin.

Here's a quick update on new things that landed on https://probelab.io and the team's tooling.

Gossipsub PX Crawling

The mighty Nebula crawler now includes functionality to discover and crawl peers not only through the Filecoin DHT, but also through Gossipsub's Peer Exchange message primitive. The work was done as part of this PR (dennis-tra/nebula#92). The results from this extra functionality are already included in ProbeLab's weekly reports - see latest/Week 27 report: https://probelab.io/filecoin/dht/2025-27. This is a related libp2p issue raised as part of this work: libp2p/go-libp2p-pubsub#617.

Filecoin Power by Agent Plot

As part of the Filecoin Weekly Network Health reports, we are now publishing the following "Power by Agent" plot (example plot from latest/Week 27 report): https://probelab.io/filecoin/dht/2025-27/#powers_by_agent_plot-plot. The reason and investigation around the fact that the majority of agents appear under an "unknown" agent is discussed here: probe-lab/website#170.

Expose map of PeerID to Agent Type and Version

After a community request, we are making available the mapping of PeerID to Agent Type and Version. You can find more information about the relevant endpoint in this GH issue: probe-lab/website#172. Feel free to get in touch with the ProbeLab team if you're interested in this data.
