I want to know the total bandwidth of the guard nodes. I went through https://metrics.torproject.org/network.html#bandwidth but I saw only the graphs. I want to know the value.
You can find the advertised bandwidth values in the bandwidth.csv file, which is linked below each metric graph.
As explained on the Tor Metrics Portal: Statistics page, each row of this file has the following fields:
The rows where
isguard column is t(rue) will give you the bandwidth for the guard nodes.
Please note that there are two rows where
isguard is equal to t for each day: one for the
Guard-only nodes and the other for the
Guard & Exit nodes. So you just need to add them to get the total value.
