Re: Monitor network tool

elaborate please. Are you looking for a promiscuous network listener? Or, are you looking for something that will report via or to your VMS box. What network protocols are you running? what sort of network complexity do you have?

Re: Monitor network tool

Edgar,
welcome to vms forum.
OpenVms has a little monitor tool, called monitor. You can see various system parameters and network data.
I think is limited for your purpose but it is a little help for you.

Re: Monitor network tool

Peter's comment is very important RE: sort of network ?

Most newer LANs using twisted pair make use of switches. A 10/100 switch will only send traffic specifically going to a port, to that port :-)

This means if your VMS box is on port 2, you will only be receiving traffic for yourself, and will never see any traffic going to or from any other ports of that switch (or any other switch in your company).

If you are in charge of your network or have management access to the switch, you might be able to configure it to duplicate all traffic and transmit it to one port, thus "seeing" everything that is going on (sorry I don't remember the term for this setup).

But short of this, any and all software you run on VMS will see traffic to and from the VMS box only (except for broadcast packets, which usually are not very interesting).

Re: Monitor network tool

One very useful tool to determine if the problem is your node is SDA.

Analyze/system

sho lan/count

there will be many pages of output. Look for failures or errors. Things like alignment errors, receive or send failures may provide some supported indications..
