[tor-talk] How to get the running state of a Tor relay by its fingerprint?

[Lucon Yang]

Now I know I can use https://metrics.torproject.org/exonerator.html to get
the running state of the relay if I have its IP address. But a relay may
change its IP address over time, which makes it difficult with this method.
So is there any way to get the running state of a relay if I have the
fingerprint or nickname which are more stable info of the relay?

Use "relay search" from this page...

https://metrics.torproject.org/

Nickname is not unique, so use fingerprint instead.

if it is related to a relay that has been running within the last 7 days before the query is issued
then you can use Relay Search

https://metrics.torproject.org/rs.html

or its backend onionoo:

If you want to lookup information from the past you can use CollecTor data:
https://metrics.torproject.org/collector.html

stem - a python library - can be used to consume that data:
