The A6 logs are hidden even if logged or or on ip/logs or /mlogs. I was never able to get them to successfully display on any of my units.
As for innomonitor, it will always show whatever the first error that is thrown. If its on a particular board, remove it and then restart the unit and monitor for the next error.
It sucks but its an old device not much else you can do.
I did this and the innomonitor reported to me that the hashboard I had removed was not involved.
It did not evaluate me for any error.
