Hello
I have this scheme in omnet ++ (see attachments). I need to find out what are the delays between all devices, how can I do this?
For example, in the Packet Tracer, there are consoles (cmd) where you can ping all nodes.
Maybe you can connect some additional programs to the Omnet++?

You can include a time mark in every packet, for example using addPar, if you set the parameter when the packet is sent and compare the time when the packet is received is easy to measure any delay

msg->addPar("value1") = simTime().dbl();

....
msg->addPar("value2") = simTime().dbl();
....

msg->addPar("value3") = simTime().dbl();



double v1 = simTime().dbl() - msg->par("value1");
double v2 = simTime().dbl() - msg->par("value2");
double v3 = simTime().dbl() - msg->par("value3");

This must be written in the ini. file?

In the source code, if you want to measure several delays this is a form,
if you want to measure the end-to-end delay, and you are using inet-framework, the end-to-end delay is already measured and recorded in the results files

I'm sorry, I'm a noob in omnet ++

Source code, c++ no in the ini file,
but inet already should record the end to end delay

When the simulation was running and in the logs, I did not find any data on delays

sca files at the end of the simulation, the application modules of inet should write the delay

there is very little latency data in the sca file, I need more statistics, can I increase this?

You can include more nodes, different traffic, replicate the experiment with different seeds ....

How can i do this?)
I do not enter any initial numbers at all.
The fact is that I found this project on github, and did not do it myself, so I don’t understand

What kind of code?
If the one that threw off to me
Alfonso Ariza, then I added it to the ini file

This configuration file is for inet framework, at least, inet 3.x and 4.x recorded automatically the end-to-end delay in the sca file like a histogram.
