Rasdaemon is a Platform Reliability, Availability and Serviceability monitoring tool which can, among other things, monitor ECC memory errors on supported platforms.
Installing
apk add rasdaemon
Logging
Rasdaemon logs to syslog. Syslog could be automatically monitored using e.g. logcheck and automated emails.
Additionally rasdaemon logs to /var/lib/rasdaemon/ras-mc_event.db, which could be read using ras-mc-clt (in this example faulty memory module has generated few errors):
