upgrades from any other older versions, please read the
successive Upgrade Strategies in sequence.
KNOWN PROBLEMS
----------------------------------------------------------------------
- Benign EventTarget warning messages may appear in the agent log if no
SNMP or XML targets are configured.
- Answering "Whole Root Zone" when running the install in a Sparse
Root Zone will result in errors and warnings during the installation

ENHANCEMENTS
----------------------------------------------------------------------
- The Neuron Agent's performance data as gathered by Reporter can
now be extracted by Halcyon's Neuron Core.
- If the Neuron Agent's EventTarget is configurated to send Neuron
Agent events/alarms to Halcyon's Neuron Core, the Neuron Core
will keep track of the Agent as an asset. By doing this, all
such agents can be accessed from a single central Agent Viewer
from within Halcyon's Neuron Management Portal (part of the
Halcyon Neuron Core).
Please note that the term "Neuron" no longer refers just to this
Agent product.
UPGRADE STRATEGY
----------------------------------------------------------------------
- All prior Neuron Agent patches have been integrated into
this version, and thus must be uninstalled. Please read the
uninstallation instructions that came with each patch.
For your convenience a utility can be found in the product
tarball's "util" subdirectory which will remove the latest
patches. Its output indicates which patches it is looking
for and whether it has found them.
- Any product customizations provided by Halcyon (not to be
confused with user alarm scripts or actions) may need to
be updated. Please contact Halcyon Support if you have
any such customizations.
For your convenience, a utility to discover customizations
can be found in the product tarball's "util" subdirectory.
- This release is compatible with the prior version. For
upgrades from any other older versions, please read the
successive Upgrade Strategies in sequence.

VERSION/DATE: 3.0.0/2009-05-15
ENHANCEMENTS
----------------------------------------------------------------------
- Added the Neuron Portal, a module that can centrally track the
availability and status of other Neuron Agents, monitored objects,
and pingable hosts.
- The Neuron Agent's EventTarget now has the ability to send Neuron
Agent events/alarms to Halcyon's Neuron Core. This enables events
to be viewed and managed centrally, and easily allows forwarding
and filtering to 3rd party Enterprise Management Frameworks using
the Halcyon Neuron Integration product.
Please note that the term "Neuron" no longer refers just to this
Agent product.
BUG FIXES
----------------------------------------------------------------------
- Fixed occasional errors in IPC statistics.
- Fixed problems discovered with "CPU Usage" of PrimeAlert
SystemMonitor and enhanced the definitions/calculations used in the
"Physical Memory" section of PrimeAlert SystemMonitor module.
- Fixed occasional problems with "Filesystem Usage" section of
PrimeAlert SystemMonitor module.
- Fixed an occasional Neuron agent memory growth condition.
- Fixed occasional problems with the text of the alarm close event
traps sent from Neuron.
- Fixed occasional event message translation failures that result in
dropped notifications.
- A problem was fixed where file scanning operations would miss lines
written to a logfile when the log was being written to at a
very high rate. Note that this problem did not affect PrimeAlert
LogFileMonitor, only certain other modules or features that used
the specific affected subsystem. This includes PrimeAlert Hardware
Monitor and PrimeAlert EventGateway (used to receive traps from
other devices or systems).
- Fixed the problem where long module instance names would affect the
functionality of certain modules.
- Agent startup more resilient to errors in circular logfiles.
