Metric to show incoming requests and transactions

hi all,

I hope this finds you well. I am trying to find a metric using:

curl localhost:PORT/metrics

On one of my relay nodes. The metric I am looking for is one that would show me attempted (and rejected) incoming connections. Is there one in the cardano-node metrics? Or should I look in the node_exporter?

Also, in the config.json for cardano-node: I have seen this:

“TraceTxInbound”: false,
“TraceTxOutbound”: false,

Are these tracers (once turned on) supposed to output a metric to show transactions moving through the nodes?

Any suggestions are greatly appreciated,

Cheers,

A
