Add gauges for allocated memory for queued UDP and TCP packages #1503

peterbueschel · 2019-09-30T18:21:11Z

Two new states will be added to the tcpstat collector called rx_queued_bytes and tx_queued_bytes.
For UDP datagrams an additional collector 'udp_queues' can be used to expose the total lengths of the tx_queue and rx_queue.

@SuperQ and @discordianfish this changes gives us the option to check for overloaded UDP + TCP processing.
The names of the new TCP states and the UDP metric can be discussed.
The current reasons are just:

I don't want to add another collector for the same exposed file, so I just added the new states to the tcpstat collector.
I chose the name 'udp_queue' instead of 'udpstat' as UDP has no state.

One hint, you can always git commit --amend then git push -f to fix any commit messages.

peterbueschel · 2019-09-30T18:48:39Z

Yes, thank you. This was also my intention, but I think I did something wrong with reset and rebase. So, I got also the changes from the infiniband-commits into my first PR. Couldn't get rid of them...
So, I went back to my first commit ever created a new PR and baam the typo was also again in the test file. Used this Github-UI to "quickly" fix the typo (of course without signoff) and baam DCO starts with complaining.
Then, trying to run git commit --amend ... and baam it wanted to add also the infiniband files again to the PR...
:-) I should avoid any minefield today...

discordianfish · 2019-10-14T21:12:51Z

Thanks! So all the parsing should eventually be moved to https://github.com/prometheus/procfs
I'm fine with just merging your tcpstat changes as they are, but the udp_queues collector's parsing should be added to procfs first and then use here.

Two small things I forgot to ask about.

Please add a changelog entry
