AsItHappens is a real-time network statistics collector and grapher. It collects data from devices over a network via ICMP and SNMP and displays them on a graph, optionally storing collected data in a database for later retrieval. Collection types include network response, bandwidth usage, processor usage, memory usage, Cisco NBAR, and Cisco NetFlow. AsItHappens polls data in regular intervals, which can be in the order of milliseconds, to give immediate feedback on network performance. AsItHappens can also graph flow information from packet capture files.

Changes:
This release adds two major features to
AsItHappens. First, AsItHappens now includes an
embedded database that is used by default, instead
of relying on an external MySQL install. Second,
AsItHappens now has the ability to store groups of
collecting graph windows as a "layout" and restore
these at a later time. Other minor enhancements
are also included, such as per-device
"remembering" of SNMP community strings. The
release also fixes some significant bugs,
including an "OutOfMemory" error while collecting
to the database and NetFlow graphs not shutting
down properly.
