## Firing Alerts

----- Time: 2023-11-11 23:12:29.934 +0000 UTC Summary: Too many bridges are dysfuntional Description: The fraction of functional bridges is too low for rdsys

I went to look at bridgestrap right after this alert, and bridgestrap seems to be doing fine. So I am wondering how to debug it on the rdsys side -- to understand which bridges it is considering, and which ones it thinks are down and why -- but I don't know how to. I added a comment to https://gitlab.torproject.org/tpo/anti-censorship/rdsys/-/issues/177 as a poor substitute. :)

Yes, I think adding that information will be useful to debug it. And I'm planning to work on bridgestrap this week, I hope to come along to do it. I see this problem is usually appearing for a short period of time, ~30min that is the period of rdsys between scans on the bridge descriptors. It does happen when there is a restart on either rdsys or bridgestrap, but also sometimes on other situation that I haven't identified. I propose modifying the alert, so is only triggered if the problem is at least for 1h, I think is fine to ignore this problem if is just for 30mins there: https://gitlab.torproject.org/tpo/tpa/prometheus-alerts/-/merge_requests/38 -- meskio | https://meskio.net/ -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- My contact info: https://meskio.net/crypto.txt -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Nos vamos a Croatan.
