Overview
This release is a feature release which adds the ability to gather
measurements on a periodic basis and store them in CSV format.
Measurements are available for different layers of the protocol stack and are
useful for traffic measurements and performance monitoring.
The release also supports new load balancing capabilities within the Message
Router Functionality through the ability to configure SLS rotation and
inversion on a per Custom Profile basis.
The release provides a fourfold increase in capacity for PCAP trace files
allowing more information to be retained, includes enhancements to MAP

Periodic Measurement Collection
This release adds the ability to gather measurements on a periodic basis and
store them in CSV format. Measurements are available for different layers of
the protocol stack and are useful for traffic levels and performance
monitoring.
Traffic measurements include, for example, the number of messages sent and
received, the number of octets sent and received, the peak traffic rate and
peak link utilization. Performance monitoring includes features such as error
counts (to assist detection of transmission path issues), routing failure causes
(to detect possible configuration issues) and a number of other parameters to
assist with smooth operation of the network.
Measurements are collected on a per-entity basis (eg per-link, per-origin,
per-network context) basis according to the type of measurement. The
frequency of measurement collection can be selected on a per measurement
type basis from the following values: 5 min, 10 min, 15 min, 30 min, 1 hour,
4 hours and 1 day.
Measurements are logged to a file called “stats.csv” in the syslog/stats
subdirectory of the user account. The file will accumulate data until the file
size reaches a maximum at which point a new file will be created and the
original will be rotated into a file called “stats.n.csv” where n is a digit. A
maximum of 10 files will be retained.
This release supports collection of the following measurement types:
