Hi all,
I have a shell script that hits some random websites.
Tools like iperf send lots of TCP/UDP messages to measure latency and
bandwidth. But I am processing application layer headers in the P4 switch.
So, looking for some ideas, from the community, regarding what tools will
be apt to observe the bandwidth, latency, etc. in such a scenario.

Hi all,
I will just try to rephrase the issue in my experimental setup in a better
way.

I need some help in measuring RTT, throughput, and memory usage for my
experiments.
For memory usage, I have developed a shell script that uses ps and pmap
Linux tools and profiles RSS(RES) RAM per second for IDS and P4 BMv2.

For throughput and RTT, measurements I looked at iperf, hping, ping, etc.
tools.
The problem is they all send TCP/UDP packets for network performance
monitoring.

Now, my P4 base application layer firewall solutions become activated, only
if packets have something on top of the TCP/UDP header. I guess standard
network performance monitoring tools will not be able to handle this issue.

Let me know if someone has some experience with some tools where I can
monitor the network performance via some higher layer probe packets like
HTTP, TLS, and DNS. These are the protocols I am currently working with.
Anyone have some experience with the firefox network monitoring tool?
