1.0.1 1.0.0
======================================================================
VERSION/DATE: 2.1.0e/2008-05-02
ENHANCEMENTS
----------------------------------------------------------------------
- Added support for Sun MC 4.0.
- Improved logfile analyzer performance.
- Module supports access log rotation by scanning the access log and
all archived access logs for web server traffic.
- Module supports local timezone changes by only analyzing access logs
before and after a timezone change. During a timezone change,
logfile analysis is temporarily halted.
- Both monthly and daily virtual domain traffic are now reported.
- SUN's webserver performance statistics file can now be entered as a
module load parameter. Thus, the performance statistics file can
be set to any arbitrary filename.
- Virtual domain traffic is now computed only when at least one
virtual domain is being monitored. That is, at least one row on
the "Current Month" table is enabled.
- Dropped support for Solaris 2.6 and 2.7.
BUG FIXES
----------------------------------------------------------------------
- Module was reporting incorrect server traffic for a given
virtual hostname due to incorrect string matching. Module now
reports correct server traffic.
- Replaced the term "Monitored URL Host" with the term
"Virtual Server ID".
- Prevented irrational alarms from appearing at module load time.
- For "Current Month" table, the term "Identifier" was replaced
with the term "Description".
UPGRADE STRATEGY
----------------------------------------------------------------------
- If PrimeAlert for Sun Web Server version 2.1.0b was previously
installed, please follow the steps below for upgrading to version
2.1.0e.
1) If necessary, update 'Virtual Server ID' values in the
'Current Month' table to match virtual server identifers
logged on the server's access log.
2) Install PrimeAlert for Sun Web Server version 2.1.0e.
3) Stop the agent.
4) Delete all files under:
[ESDIR]/log/https-[Web Server Instance]_[Module Instance]
where ESDIR is /var/opt/SUNWsymon for a SUN MC agent
and ESDIR is /var/opt/Neuron for a Neuron agent (usually)
5) Start the agent.
KNOWN PROBLEMS
----------------------------------------------------------------------
- Problem:
Sun Manager Center 3.6 and up is experiencing problems serving help
files from the server layer.
Workaround:
Please refer to Troubleshooting for a workaround to this problem.
- Problem:
Some folders are empty or cannot be opened when selecting data
properties for use with Sun Management Center Performance Reporting
Manager or Group Operations
Workaround:
See the FAQ for details on how to work around this issue.
- Problem:
If the module has been loaded with an incorrect "Web Server
Installation Path" and/or an incorrect "Web Server Instance", then
the mistake is corrected, the "Processes" and "Space Monitoring"
folders will not properly update with the correct parameters.
The "Logfiles" folder will update correctly and is not affected by
this issue.
Workaround:
Reload the module with correct parameters
NOTES
----------------------------------------------------------------------
- Server traffic results are only accurate up to the module's last
refresh operation. That is, current web server traffic is not
reported until a module refresh operation occurs.
- Performing a web server access log rotation before a module refresh
operation may cause inaccuracies in server traffic results.
If possible, perform web server access log rotation after a module
refresh operation.
- The module ignores records which have the exact same timestamp as
the last record processed during the last refresh operation. That
is, the module is configured to ignore out of sequence records.
- Partial server traffic results are stored in the agent's log
directory. These files are not deleted by the module when it is
deactivated since historical server traffic would be lost.
- Zero server traffic may be reported initially when the time required
for analyzing the web server log file is greater than the console
refresh time interval. This may occur when the size of the web
server log file is greater than 1 GB.

KNOWN PROBLEMS
----------------------------------------------------------------------
- Problem:
The rows in the "Current Month" do not refresh right away.
This is a known issue. Please refer to the TroubleShooting notes for
a workaround to this problem.
- Problem:
There is zero traffic reported in the "Current Month" folder for a
given directory.
This is a known issue. Please refer to the TroubleShooting notes for
a workaround to this problem.
- Problem:
Sun Manager Center 3.6 is experiencing problems serving help files
from the server layer. Please refer to Troubleshooting for a
workaround to this problem.
- Problem:
The rows in the "Processes" and "Space Monitoring" folders contain
incorrect parameters.
This is a known issue. The module was initially loaded with either
an incorrect "Web Server Installation Path" or an incorrect
"Web Server Instance" and then reloaded with the corrected load
parameter. The "Processes" and "Space Monitoring" folders
will not update correctly. The "Log File" folder will update
correctly and is not affected by this issue.
Workaround:
Manually change the rows in the affected folders.
- Problem:
HALiWS module uses The Webalizer for web server logfile analysis, but
The Webalizer reports at most 133 characters per line. Thus, a
Monitored Directory name can be at most about 100 characters long.
Workaround:
This is a known limitation of The Webalizer. Halcyon recommends
Monitored Directory names are not longer than 100 characters.
