It seems an interesting value to monitor but I don't see it on the default Prometheus Exporter output.
To see that value, on /etc/default/prometheus-node-exporter
add the following argument:
--collector.netstat.fields="^(.*_(InErrors|InErrs)|Ip_Forwarding|Ip(6|Ext)_(InOctets|OutOctets)|Icmp6?_(InMsgs|OutMsgs)|TcpExt_(Listen.*|Syncookies.*|TCPSynRetrans|TCPOFOQueue|TCPRcvQDrop)|Tcp_(ActiveOpens|InSegs|OutSegs|OutRsts|PassiveOpens|RetransSegs|CurrEstab)|Udp6?_(InDatagrams|OutDatagrams|NoPorts|RcvbufErrors|SndbufErrors))$"
The last commit cad8539 included the graph for TCPRcvQDrop and TCPOFOQueue under TCP errors.
Probably this will be enabled by default on node-exporter:
Why this metric is important?
