Shows the share of the peers in each crawl by the result of the dial, the connection attempt of our Nebula crawler. One value is a percentage of all peers that the crawler tried to reach in that crawl. Each peer counts once. Peers that we count as online are in no_error. For the other peers, the chart shows the error that occurred most often on their addresses. no_public_address means that the peer had no public address to dial. The no_error series is hidden by default: click it in the legend to show it. Then all series add up to 100%.
