Hey, This morning I got some users warn me that apparently our discourse installation was down but by the time I checked it was up again. There were multiple “offline” like behaviour I can see from my monitoring stack but when I went to check the logs via launcher logs app it seems like they are ou…

For clarity, I’ll add that I know logs can be in the container /var/logs but nginx, postgres and redis really show nothing abnormal in my experience. nginx have lots of logs about flooding requests (and thus limiting) for badge json of users coming from topics postgresql simply return the query ex…

launcher logs is simply a wrapper for docker logs, which can show timestamps with -t. The following should give you timestamped logs: sudo docker logs -t --tail 1000 app The lines you quoted in those two files are not related to Discourse; if you figured so because there’s discourse_app in some o…

[图片] Crius: I’m not experienced with dmesg but what I can see is a plethora of [UFW BLOCK] messages from several different IPs but of course being so many it’s hard to understand if there is a pattern. Yes, similar for me. The only ones we care about, I think, are to ports 80 and 443. Perhaps…

[图片] Ed S: and it’s quite likely there’ll be nothing there. Yep, nothing for me too. Anyway, judging by the monitoring, it seems like the container is up at all time and the home page as well but it’s literally the app not responding to requests and the fact that there is noData period in th…
