I'm looking to try and use metricbeat to triage a performance problem and want to be able to add in segments retransmitted but do not see these as being a tracked metric by metricbeat. Am I missing something or are these types of interface counter statistics not included in what metricbeat collects or can collect?
If so are there any plans to introduce them?
Every 2.0s: netstat -s | egrep -i 'loss|retran' Sat Dec 7 13:42:21 2019
76062 segments retransmited
2380 times recovered from packet loss by selective acknowledgements
TCPLostRetransmit: 25
12 timeouts in loss state
8020 fast retransmits
2767 forward retransmits
616 retransmits in slow start
TCPLossProbes: 106717
TCPLossProbeRecovery: 53571
95 SACK retransmits failed
TCPSynRetrans: 2679
For reference I did take a look at the exported fields - https://www.elastic.co/guide/en/beats/metricbeat/current/exported-fields-system.html.
