do all those DMPAFT messages look unusual to you
Tom - do all those DMPAFT messages look unusual to you ? Page timestamp is always the same and it's trying to catchup every time (???)Wondering if seeing the output of 'weectl debug --output=/tmp/something.txt' might explain the setup too...

It seems weewx starts up earlier than mysql, and thus fails to connect. It also seems to shut down earlier (on system shutdown or reboot) than mysql, leading to errors then.

A couple of things I noticed.
1. The archive period is 60 seconds (set via hardware). So all of the processing on an archive interval has to happen in less than 60 seconds or things are going to start to back up.
2. According to a the debug log output, there is a small number of fields. So there may be XType fields (such as appTemp) that need to be calculated every archive period.

> Struggles to create the charts ? Lets see some logs showing that. You did not post any debug=1 logs.I did, in fact, 400+ lines' worth. Nothing that I saw there about image generation, but it's certainly possible I overlooked it.

Rich also mentioned something similar.> I’m thinking you have the old wview not wview-extended db perhaps. You should have around 113 elements in the archive table not the small old schema with 52 or so.I think you're right. `describe archive` lists 53 rows.
