21:33 <gchristensen> it is annoying that this resolves itself incorrectly, I wonder what needs tuning to fix that

21:55 adisbladis has joined #nixos-dev

21:55 <LnL> failed -> activated -> failed

21:56 <LnL> so it did "resolve" temporarily at which point the grace period is active again

21:58 <gchristensen> I guess the grace period is what needs tweaking

21:58 <gchristensen> ?

21:59 <LnL> the grace period is fine

22:00 <LnL> failed and activating should be considered the same metric in this query

22:00 <LnL> sec

22:00 <gchristensen> aah

22:01 <LnL> https://status.nixos.org/prometheus/graph?g0.range_input=1h&g0.expr=sum(node_systemd_unit_state%7Bname%3D~%22%5Eupdate-nix.*.service%24%22%2Cstate%3D~%22activating%7Cfailed%22%7D)%20without(state)%20%3D%3D%201&g0.tab=0

22:02 <LnL> vs https://status.nixos.org/prometheus/graph?g0.range_input=15m&g0.expr=node_systemd_unit_state%7Bname%3D~%22%5Eupdate-nix.*.service%24%22%2Cstate%3D~%22activating%7Cfailed%22%7D%20%3D%3D%201&g0.tab=0

22:02 <gchristensen> oh cool

22:03 <LnL> this does mean updating channels can become pending alerts temporarily, but that's what the grace period is for

22:05 <gchristensen> andi-: https://status.nixos.org/grafana/d/LhIq8iLWk/channel-updates?orgId=1&refresh=10s&from=now-15m&to=now

22:05 <LnL> oh fancy! :)

22:44 <gchristensen> for this problem, I thought this patch would fix it: https://github.com/NixOS/nixos-channel-scripts/commit/0df25e1e8f7635b5e5aa3b728a579332c43daf59 but it doesn't appear to have

22:51 <samueldr> nixos:trunk-combined eval'd, so I guess the change did help
