The status value of TCP close_cait cannot be counted, but it actually has a value

Host operating system: output of uname -a

node_exporter version: output of node_exporter --version

node_exporter command line flags

./node_exporter --collector.tcpstat

node_exporter log output

Are you running node_exporter in Docker?

What did you do that produced an error?

I want to see ' node_tcp_connection_states{state="close_wait"} 5', but it doesnt have

What did you expect to see?

node_tcp_connection_states{state="close_wait"} 5
node_tcp_connection_states{state="established"} 2
node_tcp_connection_states{state="wait_time"} 9
node_tcp_connection_states{state="fin_wait1"} 1
node_tcp_connection_states{state="syn_recv"} 1

What did you see instead?

TYPE node_tcp_connection_states gauge

node_tcp_connection_states{state="established"} 2
node_tcp_connection_states{state="wait_time"} 9
node_tcp_connection_states{state="fin_wait1"} 1
node_tcp_connection_states{state="syn_recv"} 1

Start with the node_exporter entry point enabled by --collector.tcpstat and trace how it builds the node_tcp_connection_states metric. Compare the reported close_wait state with the states currently emitted, then verify that the expected state values appear in the collector output.
