I was looking at the total number of drops over the total number of received packets, not just the two-minute delta. Here's Greg's second reading:
Kernel Interface table Iface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg eth0 1500 0 1759965 0 105198 0 13887199 0 0 0 BMRU lo 65536 0 69 0 0 0 69 0 0 0 LRU
That comes out to about 5.9% since the stack was started, if I'm not mistaken. The old rule-of-thumb was to start worrying when rates exceed 1%.
Isn't that numnber of dropped messages though? I see dropped messages on virtually all interfaces (virtually all = just checked a few of them).
From the above:
RX-OK 1759965 RX-DRP 105198 5.9% dropped I saw number like that first which is what triggered me to do the 2-min check before and after. I had a lot of local traffic during that 2 minutes. I don't really know what all the traffic was prior to that 2 minutes. Might have been web browsing, or zypper up, etc. If all 105198 packet drops occurred in either my local switch, or my NIC, then it seems excessive. By chance, I've rebooted that PC since this discussion started. It now reports:
netstat -in Kernel Interface table Iface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg eth0 1500 0 88364752 0 21978 0 90246677 0 0 0 BMRU lo 65536 0 69 0 0 0 69 0 0 0 LRU
So, 22,000 dropped packets out of 88 million. Far less than 1%. I did a lot of SMB uploading since the reboot, thus the 88 million received packets. Most would have been simple ACKs for the transmitted packets that had a data payload. Not sure why I had a 6% cumulative drop rate earlier.
