Performance issues. Everybody had them once, and more 🙂
If you are using Windows 2012+ and Powershell, you can use the Get-Counter command in order to provide you more information regarding the TCP connections.
In the example below, we are getting the counters for IPv4 TCP:
Get-Counter -Counter \TCPv4\*
This will give an output like this:
Timestamp CounterSamples --------- -------------- 05/01/2017 19:39:23 \\btp154713\tcpv4\segments/sec : 208.768490989083 \\btp154713\tcpv4\connections established : 62 \\btp154713\tcpv4\connections active : 1085102 \\btp154713\tcpv4\connections passive : 239537 \\btp154713\tcpv4\connection failures : 742269 \\btp154713\tcpv4\connections reset : 7988 \\btp154713\tcpv4\segments received/sec : 105.882583946617 \\btp154713\tcpv4\segments sent/sec : 102.885907042467 \\btp154713\tcpv4\segments retransmitted/sec : 3.9955692055327
Quite interesting isn’t it? :p Do you want to have statistics during, for example, 10 seconds? Use the sampleInterval option:
Get-Counter -Counter \TCPv4\* -SampleInterval 10
