Versions Documented Below: 3.1.0, 3.0.0, 2.0.0, 1.1.0, 1.0.0
======================================================================
VERSION/DATE: 3.1.0/2009-08-18
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
"/docs/HALNeuronWindows/util/" directory
which will remove the latest patches.
- 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 "/docs/HALNeuronWindows/util/"
directory.
- If you have alarm thresholds set on the "Rate" field of the
Logical Disks table in the "Disk Information" section, make
sure the size of the alarm threshold is appropriate and of
the right type considering the changes mentioned in the Bug
Fixes section above. IE: Use a "greater than" threshold for
an increase in disk usage, and the values reported will now
be in KB/second averaged over the table refresh interval
(default give minutes).
- For upgrades from versions older than v2.0.0, 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.
======================================================================
VERSION/DATE: 3.0.0/2009-05-15
ENHANCEMENTS
----------------------------------------------------------------------
- PrimeAlert Reporter is now available in the Neuron Agent for Windows.
- 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.
- The 'Dynamic LogFile Naming Mode' was added to the PrimeAlert
LogFileMonitor on Windows.
BUG FIXES
----------------------------------------------------------------------
- To reduce nuisance alarms the "% Physical Ram Used" is now a moving
average over a number of refreshes.
- Fixed occasional computation errors in the Disk Usage Rate:
The Logical Disk "Rate (/sec)" field has been changed from "Rate
of change of Available disk" to "Disk Usage Rate of Change".
Thus when more space is used on a disk, the value will be positive.
An error in the rate calculation itself has been corrected.
The units indicated in an alarm status message has been corrected.
Both "greater than" and "less than" alarm thresholds may now be configured.
- Fixed an occasional Neuron agent memory growth condition.
- Fixed occasional problem with the text of the alarm close event traps
sent from Neuron.
- Fixed occasional event message translation failures that result in
dropped notifications.
- PrimeAlert EventLogAlert module is now more resilient to unexpected
data feed errors.
- 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
EventLogAlert, PrimeAlert Hardware Monitor and PrimeAlert
EventGateway (used to receive traps from other devices or systems).

ENHANCEMENTS
----------------------------------------------------------------------
- Added capability to sort tables based on alarm severity, field
name and field values.
- The interface will automatically update after a management operation
has been performed.
- Single button to update the navigation and details frames.
- Color coded links for more clarity.
- User interface improvements:
1) Default size of Attribute Editor window is larger
2) Hierarchy frame is resizable
3) Hierarchy content does not wrap making it easier to identify
navigation folders

windows.
5) Improved color scheme for clarity.

using PrimeAlert FileSizeMonitor.
- Added capability to specify the alarm severity within PrimeAlert
FileSizeMonitor for a file that does not exist.

if an action does not meet the required criteria.
- Added Windows Server 2003 support.
- Added capability to configure email notification during install.
NOTES
----------------------------------------------------------------------
