Is there a reliable way to make sure everything is working correctly?

[Muffexx]

Hello there,

I am plotting and farming since three weeks. My debug log sometimes shows various errors (c.f. Error examples), but overall everything seems to work correctly.

Is there a reliable way to make sure everything is working correctly?

1. Can I be assured that UPnP is working if all connections have at least 0.1MB traffic in both directions?
2. Is it enough that I'm "connected" and "synced"?
3. Anything else that should be taken care of?
4. Is there some wiki that provides this information?
5. Can anyone explain these various errors?

regards

1. No idea
2. . No
3. You should check that your plots are checked in < 30sec (this can only be seen in the logs AFTER you put the logging into "INFO"-Mode.
4. Not that I am aware of

Thanks for your answer. Even though my questions are not fully answered yet.
Regarding 3. I think this has been changed in v1.1.3 as Warning does now log your lookup time for eligible plots (see here).
