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.
