Thank you for your answer,

so in my language, the switch cannot handle that many packages and just discards them?

Thanks!

Discard is usually when you queue is full, like when there is microburst.

why don't you just log onto your switch, and throw some show commands at it? maybe start debugging?

observium gives you the ability to quickly navigate through your devices and see statistics. it doesn't fix your network.

Observium calculates the packages per second for a 5 minute average of these counters. so 300m pps = 0,3 p* (5 * 60) = 90 discards in 5 minutes

Thank you guys!

You're awesome. I just got all the info I need, I would start debugging, but first I need to understand what I'm looking for. Observium was the program that helped spotting the errors. You are the guys who helped me understanding the things. I am sorry if I annoyed you with silly questions.

Best!

For error counters, the dot3 stats graphs will show per-errortype statistics.

but these double the per-port i/o load as they include as much data as all of the other port counters combined :)
