      After many months of improvements, I have finished a new release
      of Orca. This does many of the things people have been requesting,
      such as measuring disk space usage and the capability to make
      plots with many Ethernet interfaces. I am including the major
      feature release at the end of this message.

      To see what Orca can do, check out

      http://www.geocities.com/ResearchTriangle/Thinktank/4996/orca-example/

      To get Orca, go to

      http://www.geocities.com/ResearchTriangle/Thinktank/4996/pub/

      and get orca-0.24.tar.gz.

      This version of orca includes the latest version of orcallator, 1.19.

      Enjoy,
      Blair

      PS To continue development of Orca, I'm looking for some people who
      would be willing to have a link from my pages to your Orca pages to
      show that Orca is being used.



      New in Orca version 0.24.
      1) Installation notes. Due to the way Orca generated image and HTML
      files are named, read the INSTALL file. Otherwise, you will have
      some left over cruft that will waste disk space and you will have
      to reload all of your source data files.
      2) Orca now runs under older Perls: Perl 5.004_01 or later.
      3) Switch to generate PNGs instead of GIFs. They take up 1/3 less disk
      space and are created at least 10% faster. If you want Orca to
      generate GIFs instead of PNGs, give it the -gifs flag.
      4) Read in .gz files using gunzip, .Z files using uncompress, and .bz2
      files with bunzip2.
      5) Add to the plot title the type of the plot (i.e. 'Yearly') in
      every image.
      6) Add a href field for a plot. This, if defined, appends a HREF to a
      target name letting you point the user to a page to get more
      information. The default orcallator.cfg has these added to point
      to the new documentation web page
      http://www.geocities.com/~bzking/docs/orcallator.html for all
      orcallator.se recorded data.
      7) Add a new option named base that lets the user specify either a base
      of 1000 or 1024 for autoscaling plots. This is useful for memory
      (base 1024) vs network (base 1000) measurements and is used in
      generating correctly calculating the base to use in calculating
      the Y axis.
      8) The word logarithmic can now be used for a plot to create a
      logarithmic Y axis scale.
      9) Orca no longer lists all the source files it finds to shorten verbose
      output. This output is now generated if the verbose level is greater
      than one.
      10) Do not overwrite existing HTML files when creating new versions until
      the new version is finished. This allows people to better view
      existing pages until the new page is completely finished.
      11) All generated HTML and image filenames are now created using
      a different set of mappings. Now
      orcallator -> o
      orca -> o
      _times_ -> _X_
      _percent_ -> _pct_
      _number_ -> _num_.
      All older installations of Orca will need to be renamed unless you
      want to load in all your data again. You can perform this renaming
      on your files by running make upgrade, or if you have directories
      that are not normally covered by the Orca install, run
      src/upgrade_installation followed by the list of directories to search
      in. Pass the -n flag to upgrade_installation if you want to see
      the renames that will be performed without actually performing them.
      12) New HTML and image filenames are shorter, which can save 10% in
      disk space on a large installation according to du -k. Also, now
      plots containing arbitrary many data sources can be plotted without
      exceeding the maximum file lengths.
      13) Add locking so that only one Orca can run on a single configuration
      file at one time.
      14) Include and require RRDtool 1.0.7.2 and Math::Interpolate 1.05.
      Include Data::Dumper 2.101, Digest::MD5 2.09, Storable 0.6.5, with
      Orca.

      These following changes are what's new in orcallator.se 1.19 since
      version 1.7 which was included with Orca 0.23. All of the changes
      below are taken advantage of in the included orcallator.cfg and
      start_orcallator files.

      15) Orcallator.se now has a web page describing the various measurements
      it makes. See http://www.geocities.com/~bzking/docs/orcallator.html.
      16) If the environmental variable WEB_SERVER is defined, use its value of
      the as the name of the process to count for the number of web
      servers on the system. If WEB_SERVER is not defined, then count
      number of httpd's.
      17) If the COMPRESSOR environmental variable is defined, then when a new
      log file is opened for a new day, the just closed log file is
      compressed using the COMPRESSOR command in the following manner:
      system(sprintf("%s %s &", COMPRESSOR, log_file)
      COMPRESSOR should be set to something like "gzip -9", or "compress",
      or "bzip2 -9". If the configure script finds both a compressor and
      uncompressor tool, such as both gzip and gunzip, then start_orcallator
      will inform orcallator.se to compress the log files at the end of a
      day.
      18) New measurements. The first column lists the define that must
      be passed to the SE interpreter to obtain the measurement. If you
      use the WATCH_OS define, then all of these are now measured.
      WATCH_MUTEX - ncpus - number of CPUs on the system
      WATCH_CPU - #proc/s - 5 minute average process spawn rate if root
      WATCH_CPU - #proc/p5s - maximum 5 second process spawn rate if root
      WATCH_CPU - scanrate - page scan rate in pages per second
      WATCH_DISK - disk_runp_c\d+t\d+d\d+ - run percent for each disk
      WATCH_DISK - disk_rd/s - system wide read operations per second
      WATCH_DISK - disk_wr/s - system wide write operations per second
      WATCH_DISK - disk_rK/s - system wide kilobytes read per second
      WATCH_DISK - disk_wK/s - system wide kilobytes written per second
      WATCH_RAM - freememK - number of free kilobytes of memory on the system
      WATCH_MOUNTS - mntC_* - capacity of disk in kilobytes
      WATCH_MOUNTS - mntc_* - inode capacity of disk
      WATCH_MOUNTS - mntU_* - used capacity of disk in kilobytes
      WATCH_MOUNTS - mntu_* - used inode capacity of disk
      WATCH_MOUNTS - mntA_* - available kilobytes for non-root users
      WATCH_MOUNTS - mnta_* - available inodes for non-root users
      WATCH_MOUNTS - mntP_* - percentage of kilobytes used for non-root users
      WATCH_MOUNTS - mntp_* - percentage of inodes used for non-root users
      19) Add some smarts so that if the number of interfaces, physical
      disks, or mounted partitions changes, then a new header is printed.
      This will prevent column name and data mixups when the system
      configuration changes.
      20) Prevent a division by zero in calculating the mean_disk_busy if the
      number of disks on the system is 0.
      21) Fix a bug in the disk_mean calculation where it was being divided
      by the wrong disk_count. Now it should be much larger and in scale
      with disk_peak.
      22) Increase the number of characters for each network interface from four
      to five.
      23) If WATCH_YAHOO is defined, then process the access log as a
      Yahoo! style access log.
      24) Restructure the code to handle different web server access log formats
      easier.
