INSIGHT:A Distributed Monitoring System for Tracking Continuous
Queries
INSIGHT is a distributed monitoring framework
for constructing
large-scale data aggregation and continuous event monitoring
applications, such as
IP traffic monitoring (DDoS attacks), network anomaly
detection (Internet worms), accounting and bandwidth provisioning (hot spots, flash crowds),
sensor monitoring and control, and grid resource monitoring.
At the core of these applications is a distributed query engine that
aggregates information and performs continuous tracking of queries
over collections of physically-distributed and rapidly-updating data streams.
The underlying aim is to provide a global view of information in the system
at a reasonable cost and within a specified precision bound.
To achieve this objective, INSIGHT should (a) scale to
a large number of streams and query attributes,
(b) incur minimal communication overhead for aggregating query results,
(c) be time responsive for quickly identifying anomalies,
and (d) be able to bound the inaccuracy of the computed value for the aggregate function.
