Classification

Node classification:

  • offline - A peer that was never seen online during the measurement period (always offline) but found in the DHT
  • dangling - A peer that was seen going offline and online multiple times during the measurement period
  • oneoff - A peer that was seen coming online and then going offline only once during the measurement period
  • online - A peer that was not seen offline at all during the measurement period (always online)
  • left - A peer that was online at the beginning of the measurement period, did go offline and didn't come back online
  • entered - A peer that was offline at the beginning of the measurement period but appeared within and didn't go offline since then

Agent Version Analysis

Overall

Includes all peers that the crawler was able to connect to at least once (dangling, online, oneoff, entered)

Dangling Nodes Only

Includes all peers that were seen going offline and online multiple times during the measurement.

Online Nodes Only

Includes all peers that were not seen offline at all during the measurement period (always online).

Oneoff Nodes Only

Includes all peers that were seen coming online and then going offline only once during the measurement period

Entered Nodes Only

Includes all peers that were offline at the beginning of the measurement period but appeared within and didn't go offline since then.

Resolution Statistics

Resolution Classification:

  • resolved - The number of peer IDs that could be resolved to at least one IP address (excludes peers that are only reachable via circuit-relays)
  • unresolved - The number of peer IDs that could not or just were not yet resolved to at least one IP address
  • no public ip - The number of peer IDs that were found in the DHT but didn't have a public IP address
  • relay - The number of peer IDs that were only reachable by circuit relays

Agents

Latencies

Overall

Connect measures the time it takes for the libp2p host.Connect call to return.

Connect plus Crawl includes the time of dialing, connecting and crawling the peer. Crawling means the time it takes for the FIND_NODE RPCs to resolve. Nebula is sending 15 of those with increasing common prefix lengths (CPLs) to the remote peer in parallel.

By Continent

Cloud

The number next to Total indicates the number of unique IP addresses that went into this calculation.

AV = Agent Version

  • # Final AV - The last agent version that was observed in this measurement period
  • # Transitions - How often did this particular peer change its agent version
  • Distinct AVs - Distinct agent version that this peer transitioned between (could have had a single AV multiple times)

Terminology

  • visit - Visiting a peer means dialing or connecting to it. Every time the crawler or monitoring task tries to dial or connect to a peer we consider this as visiting it. Regardless of errors that may occur.

Node classification:

  • offline - A peer that was never seen online during the measurement period (always offline) but found in the DHT
  • dangling - A peer that was seen going offline and online multiple times during the measurement period
  • oneoff - A peer that was seen coming online and then going offline only once during the measurement period multiple times
  • online - A peer that was not seen offline at all during the measurement period (always online)
  • left - A peer that was online at the beginning of the measurement period, did go offline and didn't come back online
  • entered - A peer that was offline at the beginning of the measurement period but appeared within and didn't go offline since then

IP Resolution Classification:

  • resolved - The number of peer IDs that could be resolved to at least one IP address (excludes peers that are only reachable by circuit-relays)
  • unresolved - The number of peer IDs that could not or just were not yet resolved to at least one IP address
  • no public ip - The number of peer IDs that were found in the DHT but didn't have a public IP address
  • relay - The number of peer IDs that were only reachable by circuit relays
