Anyone can give a tip? What the best way to monitor a Internet Link? I mean, not just with ICMP.
If you are referring to "link status" as in reference to the question "do I have an electrical connection between this network port and the one on the other end of the cable" then you probably want to be looking at SNMP.
If the machine that you are looking to monitor only has a single interface then if that system has no link, it also has no way to tell anyone that so SNMP isn't of any value. As such net_connect and "ping" (or one of the other service ports) become your only usable option.
SNMP will also get you the interface traffic as will the latest versions of CDM. Obviously these depend on have a valid link up on the network that is passing this data.
Depends on what you mean by "monitor".
There's the url_response probe which does a lot.
logmon can also interact with a URL and parse the results.
Or you could write your own test and execute that with logmon or put it into a probe you write.
Or you could use net_connect to just make sure the web server's port is listening.
I mean, to get information about status of the link (UP or Down) and bandwith utilization.
Assuming you have access to the network edge device, I'd just use interface_traffic or snmpcollector with the interface options.
