• logging completely rewritten. Verbosity now much better configurable. (2004/07)
• TRAFFIC module now handles "/" characters in devicenames correctly (i.e. to monitor Cisco routers' interfaces)
• sampling will be throttled when last sample took too long. This avoids possible high load when consuming shell-commands are needed for sampling (for example the "mailq" command)
• samples will not be taken if last sampling was <10s ago

pre4

• completely new concept! The directory structure has been changed a lot, all modules are kept in a subdirectory now. The modules now run as single daemons, the main script uses signalling techniques to control the modules. This saves a lot of compilation time on every SAMPLE call. To avoid too many modules running parallel, a random scheduler has been added.
• modules now have a ".description" file which will be printed when doing the main setup.
• all perl scripts now end with ".pl"
• the SYSTEM module is now configurable to enable or disable some of its specific targets. New targets "interrupts" and "uptime" have been added. Basic OS X support (testing). MultiCPU systems fully supported. swap stats are now stored in mem.rrd, loadavg.rrd has been renamed to load.rrd. New method gathering mem and swap info on NetBSD. Comments have been added for later addition of kernel >2.4 support.
• the protocol used by the PING module is now configurable. You can also configure it to use the ping shellcommand instead of Net::Ping. The minimum number of pings to be sent is 5 now. Timing will be done by Time::HiRes (if available) and does a fallback to the previous sysdcall. If no HiRes timers are available, you will get an error message.
  For better comparison of diagrams, the initial upper border can be configured. The lower border has been adapted for logarithmic scale.
  Data will be stored in seconds now instead of milliseconds.
  The module should generate no more zombies now.
• SENSORS now has FreeBSD support
• TRAFFIC module now with OS X support. Devices are no longer configured multiple times. Taken down BSD interfaces handled correctly. Don't use DNS lookups anymore when using netstat. BSD setup patched.
• APPS now handles applications with "." in filename correctly
• DISKIO now with basic kernel 2.4 device autodetection. Some excludes applied in devicelist (fd* md*). Module seems to worn on FreeBSD now. Some comments have been added for later implementation of new Kernel 2.4 "/proc/partitions" support.
• PART module device detection corrected. Automatic excludes list enhanced. Table sorted by devicename.
• Within each module each Operating system will be handled by an own library in the "./modules/<modname>/platform/" directory. There's also a lib "common.pm" that handles all common functions and a fallback library "default.pm"
• HotSaNIC.pm is obsolete now, but is still there to support modules written on older versions. To adapt older modules to new concept, there's a wrapper script available under "./tools/"
• all global libraries from HotSaNIC.pm were split into different files, these are kept in the "./lib/" directory
• all global functions in the read-data.pl scripts have benn moved into the new HotSaNICmod.pm library. read-data.pl just initializes the module - the main loops, help texts etc are in the library.
• all read-data.pl scripts support cmdline parameters similar to sysV-style (start/stop/status ...)
• modules' configuration can be reloaded while running
• SOLARIS is now supported by some Modules: apcusv, apps, ping, system (processes, CPU, load, users, swap, mem).
• all diagram scripts are converted to PERL now
• main index now has multi-row support (mainly used for MultiCPU machines and SNMP targets)
• instead of using the shell-magic cookie (#! ...) directly, we use "#!/usr/bin/env ..." to avoid conflicts on some systems. This makes the Automake system obsolete (saves us work...).
• a lot more SNMP support had been addeed - all SNMP related core-functions are in the "./lib/HotSaNICsnmp.pm" file. These should be quite compatible with quite many SNMP daemons. If Net::SNMP isn't found, the system does a fallback to the shell binaries. (snmpget, snmpwalk, snmpbulkget, snmpbulkwalk).
• fixed bug which produces GIFs instead of PNGs regardless of settings
• all logfiles moved to the new "./var/log/" directory, PID files went in "./var/run/", all settings are linked in "./var/settings/" by the main setup script. Modules store their temp. data in "./var/modules/<modname>/"
• main setup.pl script shows usage info when called with parameter "?"
• setup will initially guess CONVERTMETHOD now
• some diagram-titles look a bit nicer now
• some files were moved and renamed, so when upgrading it may be necessary to re-run the main "setup.pl -g" to re-generate the rrdgraph script.
• some vital paths will be created automatically now
• all "use diagnostics" and "use warnings" were moved to the libraries, since once loaded they act globally in PERL.
• for better readability in system tools like "ps" or "top", the module name will be passed as cmdline parameter.
• new PID handling functions implemented
• some shell-calls have been converted to PERL syntax to avoid backticks.
• the main diagrams script has been converted to PERL. It now generates some console-output when running( some people were confused by the previous behaviour of it running silently in the background). The logfile will now be handled by rrdtimer.
• modules are automatically restarted every STIME if not running
• rrdtimer.pl uses an anlternate daemonizing method to avoid shells hanging while logging out (mostly works!)
  sending a HUP to rrdtimer, the modules will also be terminated, sending USR2 only the modules will be terminated (and will be restarted after STIME)
• main loop now sleeps more efficiently using less CPU time
• added more debugging verbosity to scheduler

pre3

• data-diskio now supports *BSD
• data-networks now has totals for input/output and a summary over the graph's time
• data-traffic now has a summary over the graph's time
• HotSaNIC.pm fixed, the module name was not detected correctly if HotSaNIC resided in subdirs containing "-" chars!

• data-diskio diagrams script converted to PERL
• rrdtimer now logs errors to the main logfile (makes debugging a bit easier)
• data-part samples configured drives only (more convenient on systems using autofs)
  It also checks if NFS partitions are configured and scans them on demand. This reduces deadlocks.
• data-worms now skips .gz and .bz2 files while scanning logs
• data-traffic has been adapted to fix the "ghost graphs" issue when graphing SNMP sources (hope it works now)
• data-traffic graphs interfaces which are "down" as "unknown" instead of a zero line.

• data-traffic has been sped-up a bit
• dupe-control checks for PIDs now
• project's contact address has changed to: hotsanic@bernisys.prima.de

• data-traffic now supports Open/Free BSD ( Thanks to Matt Burke! )
• data-traffic now supports SNMP (both GetBulk and SNMPwalk method)
• data-traffic's initial scales are set down to 1000 bytes/s for any kind of device (better readable graph at low traffic)
• data-traffic's diagram script has been upgraded to evaluate settings instead of executimg the settings-file
• data-traffic now can show a bits/s legend instead of bytes/s only
• data-network now can show a bits/s legend instead of bytes/s only
• data-part now supports Open/Free BSD ( Thanks to Matt Burke! ) - the resolution is now 1024 bytes.
• data-dnet now supports configurable logfile names ;)
• HotSaNIC.pm (a perl library containing common functions) now exists to eliminate multiple definitions and redundant functions in different modules
• all initializing stuff has been moved from "rrdgraph" to "rrdtimer"
• rrdtimer now has a signal-handler for the TERM signal to properly shut down the daemon
• the whole tool now should be CVS-proof ;)
• some "setup" scripts now exist to create initial configurations easier. They are called automatically by the main "setup.pl" script.
• "compile" now supports option "r" for recompiling (might be necessary after upgrading)
• a new module "data-diskio" exisits which reports I/O stats of the pyhsically installed harddrives
• data-worms has been rewritten completely because it wasn't sampling correctly at all. Should be ok by now.
• data-system now has BSD-support ( Thanks to Matt Burke! )
• data-system now supports sampling CPU stats for multi-CPU machines (images are being generated, but the index.html will not yet be created - But i'm working on it...) - Thanks Aide Florent for the ideas and some support!
• data-system main CPU stats may be generated in percentage instead of absolute values
• all modules can generate a browser auto-refresh tag now.
• all thumbnail images are moved to the corrosponding subdirs on the webpage to re-gain more overview.
• HotSaNIC.pm now contains a parser function for the settings. All modules have been adapted to use this function instead of parsing the lines on their own (read-data.pl and makeindex.pl are affected).
• added a directory "tools" where a few helpers could be located.
• tools: makeperlheaders (call if ping module complains about missing syscall.ph)
• stop function in "rrdgraph" script is now BSD-proof :) ( Thanx to Peter Reich! )
• tools: warnings.pl generates warnings if a defined threshold matches (for example 20KB/s on eth0 over the last 5 minutes)
• data-traffic: diagram script converted to perl now
• data-system: shows user-stats now
• all modules: main options are being transfered to the read-data scripts by rrdtimer as commandline-arguments (saves parsing of mein settings over and over for some scripts)
• setup.pl: option "y" tells the script that it shall use all available modules, settings are being backed-up instead of creating a settings.new file and leaving the original untouched
• rrdtimer: debugging mode also available in daemon-mode (configured in main settings)
• all modules: dupe control added. If a module is already running, don't start it again until the old instance exits (control-file: "running.dat").
• data-system: now with NetBSD support
• data-system: showing processes on FreeBSD

• Missing directories in the module-subdirs are now being created as they should be. Sorry for the inconvenience!
• I corrected some misbehavior with directories containing spaces. (correction may not affect every module yet - remember that the project is still in ALPHA state)

• The script now has many sub-routines which will make debugging much easier - well, at least i hope so ;).
• The main "makeindex.pl" now has been integrated into "rrdtimer" to get the whole thing more compact. To generate the html index-files just type "rrdtimer i" - that's all. I left the "makeindex.pl" in this directory for compatibility, but this is just a shellscript that calls "rrdtimer i". ;)
• The way you call "rrdtimer" has changed a bit - just type "rrdtimer" on the console to get some help.

• the "diagrams" script in the traffic-module produced some errors due to a wrong variable-assignment.
• the "diagrams" script in the part module produced errors because "rrdtool" was called with some parameters mixed up.
• the convert.sh script only converted the graphics from system and dnet. Now it handles all graphics.

• processes (sleeping, running, stopped, zombie)
• CPU time (idle, nice, user, system)
• loadaverage
• memory (free, buffered, shared, cached)
• swapfile (free, used)
