pSDash

The project is a Plotly Dash application focused on the perfSonar alarms generated by the Alarms&Alerts service.

Currently pSDash provides information about:

  • Throughput issues
  • High packet loss
  • Firewall issues
  • Bad clock configurations
  • Traceroute issues
  • Divergence from the usual path (based on the AS numbers)
  • ASN path anomalies
  • And more

Brief description of the rules and thresholds of the alarms
