Description

We need to find out if sbws is excluding any relays.

If the number of excluded relays is small, we can go below 3 torflow instances.

Respect to what?, i can think of:

  • number of relays that are in the last consensus (currently 7478)
  • number of relays for which sbws gets the last descriptor (currently 6571)
  • number of relays measured by torflow

Ah, i realize now about the detail "by all sbws instances", so are you thinking on a script that would take the relays from the consensus and see which are missing in both longclaw and bastet?, in the bandwidth files for how long?.

yes, let's compare with the consensus

  • number of relays for which sbws gets the last descriptor (currently 6571)

if we fix bug #30733, then sbws should get all the descriptors, so we won't need this comparison

  • number of relays measured by torflow

yes, let's also compare with torflow

  • sbws ignores relays unless they are in the most recent consensus that it has, so it will have a lot fewer relays than torflow
  • we can fix this issue by fixing #30727

Edit: fix formatting
