TCP/IP network monitoring

Post by mpalmier » Sat Apr 03, 2021 10:01 am

I need to monitor network TCP/IP usage on an OpenVMS system.

Ideally I would like to monitor the current network bandwidth in use, such as number of bytes transferred in a second.
The purpose of this is to understand the root cause of intense network traffic, the processes that are running this traffic and the IP destination. Is there any tool that I can use to facilitate troubleshooting?

Matteo,

for collecting and evaluating TCPIP overall performance metrics, the T4 tool comes to mind. It can collect system-wide TCP statistics including throughput data. It does not collect TCP data per process or per IP address.

The TCP performance data could be correlated with BUFIO per process data, which T4 also collects.
