retention and size cap apply live; database path applies on restart

Retention (days)

Size cap (MB)

Keep newest sessions

Record a session automatically for each daemon run

the newest N sessions never expire by age, so a quiet fortnight cannot cost you your only recorded run (0 = age only) without automatic sessions the floor above only protects runs you named by hand, which is nothing at all in normal use a size cap trims the OLDEST lines once the capture exceeds it; leave it at 0 unless you need a hard disk bound

Updates

applies live

Check PyPI for a newer MCUscope release

one request a day at most, cached across restarts; nothing but the version is fetched, and MCUSCOPE_UPDATE_CHECK=0 or =1 in the daemon's environment overrides this setting

PlotJuggler

applies live; "Save as default" also writes the config file

Stream decoded plot points over UDP

Destination

in PlotJuggler, add a "UDP Server" data source listening on the port in Destination, message protocol JSON, and enable its use-the-message-timestamp option with field ts (or tick for the MCU clock)

Sessions

archive a run as a standalone capture database, or delete one that was not worth keeping

Name	Started	Lines

Access token (this browser)

sent with every request when the daemon was started with --token / MCUSCOPED_TOKEN; stored only in this browser

Token

Ports
