Network monitor
Is there any utilities/commands I can use if I want find information about historic network traffic. I also wnat to find out why some process suddenly is generating huge amount of network traffic.
This morning I saw that the the network traffic suddenly exploded, and I want to find some information about the reason for it (process and packets on network).
I also want to get software for network and system managment. So if someone have some recommandadtion, it would be great.
regards geir

Re: Network monitor
ucx set service xxx/log=activate
ucx show dev /fu can give you statistics of that connection (e.g. bytes transferred) but only during the time the line is used.
But some scripting is required to really do some monitoring.

Re: Network monitor
For Decnet phase IV,
$ mc ncp sh known node counters
may show some response timeouts, this means that some trames were lost when talking between
your node and the node shown by the command.
see to
$ mc ncp sh exe counter
$ mc ncp sh k line counter
For Lat
$ mc latcp sh link/counter
can show various error code, see for example
http://pi-net.dyndns.org/docs/openvms0731/731final/6048/6048pro_038.html
search for
The following table lists and describes counters common to both CSMA/CD (carrier sense, multiple access with collision detect) and FDDI (Fiber Distributed Data Interface) links:
$ mc latcp sh node/counter
For Tcp/IP
do first
$ @ sys$startup:tcpip$define_commands
now you have the "standard" (in the unix World)
netstat, ifconfig, sysconfig...
so
$ netstat -i
$ netstat -m
$ netstat -s
$ sysconfig -q inet
$ sysconfig -q socket
