How to see contents of output queue of NIC in Linux and introspect frame delay

jp flag

I am experimenting with tc tool to implement prioritization of specific data coming from my computer and would like to see exatly how the frames are scheduled and how much time they spend in the qdisc queue before the transmission (before being dequeued). The goal is to make sure my tc configuration does what it is suposed to do.

Is there any tool that allows such introspection?

Suspiciously similar question here: https://serverfault.com/questions/261316/how-to-monitor-current-output-receive-queue-length-in-linux , there even are answers, but none accepted. Are you asking the same question?

Not exactly. I would like to look directly into the queue itself (if it is possible) to see what exact frames and in which order are scheduled for the transmission

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
