ok how can I determine which one If I don't have monitoring tools ,
If I did traceroute is it enough , can I do any other thing to check ,

Hello,
from a Windows machine, you could use 'pathping', that will give you an indication of where the bottleneck might be. Below is an example:
C:\Users\gpauwen>pathping 8.8.8.8

over a maximum of 30 hops:

Assuming you have access to those routers, you might connect to each an check its CPU and interface stats. Basically all a monitoring tool do is collect the same information.

@Joseph W. DohertyThanks but if we have 50 routers should I access each one speartly, it is difficult right.
I am looking for any Network tools. the command will help me with that
10-24-2021 11:38 AM
Ah, I misunderstood - though you were asking what to do if you have no tools, and weren't planning to obtain any.
There are "free" monitoring tools. For recommendations, post a new question asking for such recommendations.

@Joseph W. Doherty no you are right, I meant network tools like ping , trace , telnet ...etc soory it is my bad I should clear my qusetion ,
so no monitoring tools , is there any command or way to check where is issue without accessing routers
