Votes:

0

I have a linux machine and I need know how many NEW TCP connections there are in time. it's possible with PRTG ? what is the SNMP OID for ?

Look, it isn't the number of connections TCP in time, it's number of NEW TCP connections.

Thanks

And how exactly should those connections be distinguished from existing connections? You'd have to have a base for that :)

You should use the SSH sensor to do that. Here are some commands that might be helpful:

How many connections are currently open? netstat --tcp -an | wc -l

How many connections to a certain port are open: netstat --tcp -an | grep :80 | wc -l

How many connections to a certain host are open: netstat --tcp -an | grep 192.168.1.1 | wc -l

If you could specify your question a bit more, maybe I can come up with something :)
