ION Monitoring Web Interface

• Simple Web Interface to allow users to check on the state of the network and see some statistics about their circuits.

Monitoring Components

• Statistics Collection• Polls the Ciena software and grabs statistics• Ethernet: in/out packets, discards, errors,

operational/administrative state• Optical : operational/administrative state• “Vlan”: in/out packets, discards, errors,

operational/administrative state• Stores results in RRD files• Uses perfSONAR-PS SNMP MA to make the

statistics available

Monitoring Components

• Agent• Converts IDC’s view of circuit topology into

the ‘measurable’ topology• Caches these modified circuit topologies

for the web interface• Caches the network topology

Visualization Component

• Web Client• Retrieves the topology from the cache• Retrieves the set of circuits from the cache• Contacts the Measurement Archive and

requests statistics about the circuit

Circuit Monitoring - Future

• Enable clients in one domains to lookup information about the segments of their circuit that cross other domains• Allows clients to pinpoint which domain

issues are occurring in.• Enables individuals to write applications to

better understand and visualize circuit statistics.

ION Monitoring Interface

• Simple Web Interface to allow users to check on the state of the network and see some statistics about their circuits.

• Statistics Collected– About Circuits

• Up/down state• Utilization, dropped packets, discarded packets and

errored packets for the ingress/egress points

– About The Network• Up/down state of optical and Ethernet links.
