ENA provides a set of tools to help you monitor the performance and availability of your network:
Identifies root failure and therefore does not involve the raising of misleading downstream events. It combines data from:
- application availability monitoring through response to TCP connect requests.
- availability monitoring, which uses data collected through ICMP pings of network objects.
Services comprise of:
- a service definition, which acts as an object to which you can associate components that make up that service.
- components, e.g. device, ports, applications and other services, that make up the delivered service.
Performance and asset utilization
ENA delivers key measures of asset utilization across a range of technologies, helping you identify over- and under-utilized resources, and make purchasing decisions based on true network requirements. A host of dashlets and activity reports inform you of your network utilization.
These are the key performance and asset utilization measures:
- utilization, expressed as a % of actual traffic volume against the maximum volume that can be handled by the port.
- router measurements, e.g. CPU and processor utilization.
- switch backplan utilization.
- frame relay PVC, ATM VCC utilization.
- QoS classes.
Edge of network change
Monitors hardware changes and additions through changes of MAC addresses. For example, hardware changes and additions to the network in a remote office can significantly impact network performance. Device auto discovery, inventory snapshots and inventory reports help you know what is on your network.
All of the above are integrated within ENA, so you can use them in conjunction with other tools, and access information through events and incidents, charts, and reports (such as the Network Delivery Perspective report).
