  Change History

  v.8.3-1 (Sep.2009)

  Just a minor update-1 for 8.3 version - cannot wait until v.9 :-)

  Here is a list of changes coming with update:

  Fixes :
       - dim_STAT-Server script on start did not restat active collects (special thanks to Didier DAHIER to find it!)
       - dim_STAT-Server script is now killing all clients too when involved with "stop" action
       - Standard Bookmark kit was not installed by default within a template database (special thanks to Peter Hausdorf to find it!)
       - Linux iostat binaries updated for STAT-service to fix broken output in some cases (special thanks to Melanie Ashworth-March to find it!)

  Improvements :
       - Added UNIX signal traps to WebX
       - Replaced crypt() function to reduce WebX binary dependencies (now again compatible back to Solaris 2.6)
       - Added active collect(s) information (extending active connections)
       - etc..

  Database schema :
       - Bookmark name size was increased to 32 characters now!

  EasySTAT additional options :
       - COMPRESS and TIMER options are now integrated within EasySTAT.sh and enabled by default
       - Run forever if Hours == 0
       - Supporting integration within /etc/inittab for automated stats collecting
       - Special actions are involved on signal trap (see doc)
       - pid file is created within a working directory to simplify EasySTAT process identification

  New Add-Ons :
       - mysqlLOAD (compact MySQL stats oriented multi-host monitoring)
       - pgsqlLOAD (compact PostgreSQL stats oriented multi-host monitoring)
