Hobbit 4.0-RC1 available

[Henrik Stoerner <henrik (at) hswn.dk>]

The first release-candidate of Hobbit 4.0 was uploaded to
hobbitmon.sourceforge.net a few minutes ago.

This fixes several serious bugs, especially in the alert handling
module where use of the DURATION specification in beta6 would delay an
alert for 24 hours, and the handling of macros was very broken.

A number of platform compatibility issues have been resolved,
especially on NetBSD and AIX.

The data collected for vmstat- and netstat-reports has changed, and
this unfortunately means that the vmstat- and netstat-RRD files in RC1
are incompatible with previous versions, and also with files generated
by LARRD. You must delete files in the old format, or collection of
these data will fail. The larrd-data.log and larrd-status.log files
will contain error-messages if this happens.

Some joker disabled all of the tests on my demonstration site. So
I decided to move the "Enable/Disable" and "Acknowledge" CGI scripts
to a secured area requiring a login. This is now part of Hobbit and
can be enabled during configuration.

Several other minor bugs and improvements, the full list is below.

Thanks to everyone testing Hobbit - there are now more than 100 people
on the mailing list, which is much more than I had expected. I hope
you'll try out this version, so any remaining bugs can be squashed.

Henrik

Changes from beta-6 -> RC-1
---------------------------

* NOTE: The netstat RRD file layout has changed.  You must delete all 
  "netstat.rrd" files, or your data collection will fail. Sorry, but the old 
  LARRD format cannot cope with reality, where some systems report packet 
  counts, some report byte counts, and some have both.

* NOTE: The vmstat RRD file layout has changed, for data collected
  from Linux-based systems. You must delete all such "vmstat.rrd"
  files, or the data collection will fail. There were several 
  incompatible formats of linux vmstat RRD files - now they all
  use the same format.

* Hobbit should now work on AIX, and possibly other platforms
  that enforce strict X/Open XPG4 semantics for the ftok() 
  routine. If you were seeing messages like "Could not generate 
  shmem key..." or "Cannot setup status channel", then these
  should now be fixed. Thanks to Chris Morris for being patient 
  with me while I struggled with the finer details of SVR4 IPC.

* A new "--test" option was implemented for hobbitd_alert. Running
  "hobbitd_alert --test HOSTNAME SERVICENAME" will print out the
  rules that match the HOSTNAME/SERVICENAME combination, so you 
  can see what alerts are triggered. (Note: man-page is not updated
  with this info yet).

* Macros in hobbit-alerts.cfg were broken. Completely.

* Specifying time-values in hobbit-alerts.cfg as "10m" was 
  interpreted as "10 months" instead of "10 minutes". Since
  minutes is much more likely to be useful, the support for
  "months" and "years" was dropped, and "10m" now means minutes.

* Specifying any kind of duration meant that the alert would not
  happen until 24 hours had passed (and the alert still was active).
 
* Two new keywords in the hobbit-alerts.cfg file: 
  STOP on a recipient means that Hobbit stops looking for more 
  recipients after the current one has matched. 
  UNMATCHED on a recipient means that this recipient only 
  gets an alert if no other recipients got an alert (for
  setting up a default catch-all rule).

* A simple syntax for "all hosts" is now "HOST=*" in hobbit-alerts.cfg

* Configuring the Hobbit URL's as a root URL - "http://host/"; -
  now works, and yields correct links to the menu, the GIF-
  files, and the documentation.

* The Enable/Disable script (maint.pl) now picks up the menu
  correctly.

* The "configure" script now allows you to select a second
  CGI directory for administration scripts (the ack-script
  and enable/disable script). This second directory is 
  access-controlled; the default Apache configuration was
  updated to show how.

* The ~/server/starthobbit.sh symbolic link was not being
  re-generated if the file already existed (on some platforms).

* The hobbit-tips.html file is now generated during installation,
  so it has correct links to the icons. Previously it assumed 
  that the icon-files had been copied to the www/help/ directory.

* vmstat data for the "I/O wait cpu time" on Linux is now being
  collected. Linux RRD data-formats made identical across the
  various formats that are in use; this means any existing vmstat.rrd
  files from Linux systems must be deleted.

* Support for NetBSD 2.0 in vmstat and netstat RRD handler.

* HTTP authentication strings are now URL un-escaped, so you can
  use any byte-value in the username and/or password.

* The info-column now includes the current address assigned to 
  a DHCP host.

* A new "noinfo" tag can be used to suppress the "info" column on
  selected hosts.

* bbhostgrep no longer segfault's if you do not use the BBLOCATION
  environment setting. This kept some extension scripts from working.

* If every single network test failed, bbtest-net could loop 
  indefinitely. Seen on NetBSD.

* If the number of available file-descriptors (ulimit -n) was
  exceeded, bbtest-net would loop forever. Seen on NetBSD.

* When running http-tests via a proxy that requires authentication,
  the authentication info could not contain a ":" or a "@". The
  authentication info is now un-escaped using the normal URL
  decoding routine, so these characters can be entered as %XX 
  escaped data (e.g. to put a "@" in the password, use "%40").

* LDAP tests now try to select LDAPv3 first, and fallback to
  LDAPv2 if this is not possible. Some newer LDAP servers 
  refuse to talk v2 protocol.

* Memory debugging was accidentally enabled in beta6 - it is now
  disabled.
