Usage Examples
Retrieve link utilization on a given path
perfSONARUI can display the link utilization on all links of a given
path. It makes it possible to find, easily, the origin of congestion
that may cause performance problems. perfSONARUI retrieves the link
utilization information from perfSONAR Measurement Archives (MAs) that
can export information stored in Round-Robin Databases (RRDs). These so
called RRD-MAs must be deployed in all networks of the path being
monitored so that the utilization can be displayed for all crossed
links.
To exchange your link utilization, install RRD-MA
To view the link utilization for a path, launch perfSONARUI
Easily publish the information you collect
The perfSONAR Lookup Service (LS) makes it possible to clearly
describe the perfSONAR services that you have deployed and the network
characteristics you are publishing. The LS is the entry point for the
perfSONAR monitoring applications: they first ask the LS where they can
fetch the information requested, and then they query the services
reported by the LS.
The Lookup Service is aimed at being fully distributed but the
implementation at this stage only makes it possible to deploy a central
LS where services can register
To publish your perfSONAR capabilities, deploy a Lookup
Service
A unified looking glass for all networks
An interdomain looking glass makes it possible to retrieve,
from a
single application, information from routers located in different
administrative domains. The looking glass queries telnet/SSH
Measurement Points (MP). These MPs must be configured to relay the
queries to the routers, using SSH or telnet. The telnet/SSH MP can be
configured to accept only specific queries (or commands) to protect the
network from malicious users.
To restrict telnet/SSH access to your network, download the telnet/SSH
MP.
