Bootstrappers

Monitoring and Alerting

Status and availability of bootstrap nodes, a critical component of every network. Bootstrapper nodes help new peers discover and connect to the network.

ProbeLab's monitoring infrastructure is checking up on Celestia bootstrapper nodes' connectivity every 5 mins, utilising all available transports (i.e., TCP, QUIC, Websocket, WebTransport).

How to read the dashboards

  • Upon three failed attempts to connect to a bootstrap node with any of the transport options (i.e., if none of the attempts with any of the transports is successful), the node is considered offline and an alert is triggered.
  • If a node is offline, the corresponding tile at the top section of the dashboard turns red.
  • Upon each failed attempt to connect to a node with a particular transport, the disruption is indicated as a red stripe in the timeseries dashboard of the corresponding transport.
  • Unless all attempts to connect to a node with any of the transports fail, the top section tile remains green.

Overall Availability

Bootstrapper availability through all available transports

Bootstrappers Status Timeline (Overall)

Bootstrappers Status Timeline (Overall)

Shows when each bootstrapper was online (green) or offline (red). Each row is one bootstrapper, with its name or, if it has no name, its peer ID. Our bootstrapper monitor probes the endpoints of every bootstrapper regularly. Probes of a bootstrapper that follow each other within three minutes form one round. This timeline counts the probes of all types. A round is online if at least one probe of any type succeeded. A bar lasts until the status changes, so a time without probes keeps the last status. Hover over a bar to see its start and end time.
