all is Ok,
but if you want to check your ISP connection up time and want to make record for the same, then you can use MRTG for this, to do this you need one of these below mention access.
1. Ping access to you ISP's any server or Router ethernet port.
2. OR you have to know any http site name hosted within your ISP servers.
3. SNMP access and snmp community name and server or routers IP.(on which snmp enable)
try to make MRTG graph for ping statics. (if dont knowi this then plzz download Windows base MRTG Bundle 2.0 for this, it have ping graph script)
same grph can be createable for http port and snmp enable ethernet interface
. by this you can able to have your link exact statics + its history
If these line are usefull then plzz just inform.
