Is a monitoring tool used to monitor the transmission tunnel of the network.
With PRTG, network operators can know if the network is running fine, who and
what is using the network bandwidth, if something is wrong with the network.
With the PRTG, operators would be able to troubleshoot network problems, before
it causes downtime or economic loss.
PRTG can monitor:
Bandwidth could be monitor using SNMP, packet sniffers
Availability of the network devices websites or data bases
system parameters like CPU load, memory usage
Virtual servers, VOIP connections and so on
With PRTG, distributed monitoring is made easy by using remote probes

The structure of EMTS NOC is put in place to ease;
Interoperator and operator to vendor relationships through
clear metrics and detailed report extractions
collaboration to support SLA negotiation and improve decision
making
