But if you are your "network team", you need to check the docs for your network boxes to see what is available. I am not an expert in this stuff so I cannot really comment further. Your network team should be using these or some other technique to monitor their boxes. They can also report their statistics via snmp but this requires software that you need to purchase. They tend to have a service port that you can access via telnet. Routers and switches keep on-board statistics. Most ftp clients perform the timing automatically. To measure performance host to host, I usually just ftp a 1 GB file and time the result. If your routers and firewalls allow traceroute to work, it can tell you where a delay is.if it is a persistent delay. To measure latency across a complex network, traceroute is an option. Still, this is a start and you should ensure good communications with your system's link partner. Your average unix host is connected to an ethernet switch and can only see packets to and from it. And these days, even that becoming very rare. At best, this will only enable measurements on the local ethernet segment. With HP-UX, lanadmin can do that (in menu mode). But I will assume that your network is identical to mine and work from there.Įvery unix system that I know of has some way to see statistics kept by the lan driver. Someday, I hope, people will include a few details with their questions. The Internet Pi runs Pi-hole for DNS privacy and ad-blocking, and Prometheus and Grafana to provide Internet connection monitoring dashboards. What you can do depends on your network topology and your specific OS. Here are some nice tools in the Ubuntu repositories for command line network traffic monitoring: bmon Shows multiple interfaces at once slurm Has nice colored graphs tcptrack A favorite.
