Use (NEW_tcp_in_errs - OLD_tcp_in_errs) / (NEW_tcp_in_segs - OLD_tcp_in_segs) can calculate the error rate of received TCP packets.

Usually used to troubleshoot network problems.

doris_fe_snmp{name="tcp_out_segs"}

Value of the Tcp: OutSegs field in /proc/net/snmp. Represents the number of send TCP packets with RST mark.
