New subject: [hobbit] Hobbit 4.0.3 released

22 May 2005

      Version 4.0.3 of the Hobbit Monitor was uploaded to sourceforge.net
a few minutes ago.
This release adds a new maintenance script, native to Hobbit, so
Hobbit no longer relies on any external tools for the core
functionality.
Beginning with this release, Hobbit can no longer be used as
an add-on to Big Brother. Hobbit retains compatibility with
BB clients and extension scripts, but you can no longer run
eg. the Hobbit network test tool and have it report to a
Big Brother server.
All log files have been moved to the Hobbit log-directory,
usually /var/log/hobbit/. If you have scripts that access
these, you should change them or setup links for the old
locations of the BBVAR/acks/* logfiles.
Commandline options for all of the CGI tools have been
collected into a "hobbitcgi.cfg" file. If you have customized
your CGI scripts with additional commandline options, you should
put them into this file instead of modifying the CGI wrappers
directly, to ease upgrading.
And of course, a number of bugs have been fixed. I am grateful
to the people on the Hobbit mailing list for their great effort
with reporting bugs, suggesting improvements and testing the
early versions.
The changelog for this release is included below.
Regards,
Henrik
Changes from 4.0.2 -> 4.0.3
Bugfixes (general):

The bb-datepage and bbmessage CGI tools were reading the
POST data in an incorrect way; it worked on most systems,
but did not adhere to the CGI specification.

Bugfixes (alerting):

Acknowledgments were broken in 4.0.2.
Using PAGE=... in hobbit-alerts.cfg to pick out hosts
on the front-page was not possible. The front page is
now recognized with the name "/", so PAGE=/ will find
them.
The hobbitd_alert --test option would not pick up the
correct page-path settings from the bb-hosts file.
The BBALPHAMSG text passed to scripts as a default alert
message now includes the URL link to the statuslog.

Bugfixes (graphs and trends):

hobbitgraph.cgi could show "@RRDPARAM@" on graphs if
it was matched by a NULL string (would happen for mailq
graphs).
RRD files were not being updated while a status was
blue (disabled), even though status messages were received.
Changed so that blue logs are passed off to the RRD
The "disk1" graph definition failed to take into account
that the numbers logged were already in KB of data. So
the axis-label was wrong.
parser - we might as well track data when it's there.
The "mailq" RRD handler now finds the queue-length
regardless of whether it is before or after the "requests"
keyword in the "mailq" or "nmailq" status message.
If the "apache" data collection was specified for a host,
but the host had no "http" tests, a bogus http status report
was being generated.
Network statistics used a conversion that would overflow
on 32-bit systems.

Bugfixes (web pages):

Some header/footer files for the snapshot report
were missing.
The "info_header" and "info_footer" files were not being
used for the "info" column pages.

Bugfixes (installation):

Fix file-descriptor leak in the "setup-newfiles" tool
used during installation. This could cause "make install"
to abort while installing new files, on systems with a
low setting for the max. number of simultaneous open files.
Some systems keep libraries in a /lib64 directory - this was
not being searched by the configure script.
If Hobbit was built without SSL support and an SSL network
test is configured, it will now always fail with a meaningful
error message.
If the configure script found SSL- or LDAP-libraries, but
these could not link, the build would not disable SSL-
and LDAP-support and therefore it failed. If the libraries
do not work, disable the support.
The SSL test would link without required network support
libraries on some platforms.
The options for overriding SSL- and LDAP-include files
did not match the documented name.
AIX systems built with gcc were missing the OSDEF compile-
flags.

Improvements:

All remnants of Big Brother compatibility have been
removed. If you want to stick with the old Big Brother
tool, use bbgen. This allowed for some much needed
cleaning up of the bbgen code that loaded the status
data, especially for the handling of purple status logs.
Also, the sending of messages has dropped all support
for the Big Brother method of sending "page" messages
when a status-message is sent with an alert-color, so
the BBPAGE and BBPAGERS settings are no longer used.
The maint.pl script has been removed. A new tool,
hobbit-enadis.cgi, replaces this with a native Hobbit
tool. If you are upgrading, you should change the
~/server/www/menu/menu_items.js file to point link to
"hobbit-enadis.sh" instead of "maint.pl".
The "info" column page now includes a form to disable
and enable tests for a single host. If you prefer not
to have this on the info page, add the option "--no-disable"
to the hobbit-cgi/bb-hostsvc.sh wrapper.
Some logfiles have been moved to the normal log-file
directory - /var/log/hobbit:
nkstatus.log (from ~hobbit/server/)
notifications.log (from ~hobbit/data/acks/)
acklog (from ~hobbit/data/acks), also renamed to
acknowledge.log

The hobbit-mailack CGI will now find a "delay=DURATION"
line in the mail message, and use that as the duration of
the acknowledgment. Reports show that there are some
types of mail/SMS systems where you cannot modify the
message subject.
Paul D. Backer contributed "favicon" images generated
from the Hobbit "recent" GIF files. These have been added
and are now loaded from the Hobbit web/*_header files,
so that browsers supporting this (Mozilla, Firefox) will
display a favicon-image in the titlebar or on the
page-tab holding the Hobbit webpage.
Two new settings in hobbitserver.cfg can be used to
restrict which filesystems are being tracked by Hobbit.
The NORRDDISKS / RRDDISKS settings are regular-expressions
that the filesystem names are matched against. See the
hobbitserver.cfg(5) man-page.
Hobbit now works with RRDtool 1.2.x. Due to a bug in
the first 1.2.x releases of RRDtool, you must use at least
version 1.2.2 with Hobbit.
A new report-output option lets you save a CSV (comma-
separated values) file with the availability data for
each host+test in Hobbit. This allows for further
processing of the availability data eg. importing it
into a spreadsheet. This can be selected from the report
request webpage.
It is now possible to define different values for an environment
setting in hobbitserver.cfg, depending on a new "--area=..."
command-line option for all tools. See hobbitserver.cfg.
Apache 1.x performance data are now graphed correctly,
by mapping the "BusyServers/IdleServers" data into the
BusyWorkers/IdleWorkers datasets used by Apache 2.0 RRD
graphs.
sendmail RRD's for sendmail 8.13+ now tracks the number
of "quarantined" messages also. You must delete any existing
sendmail.rrd files for this new data item to be tracked.
All RRD-updates now use the RRDtool "--template" option to
map values to RRD datasets. This should keep us from
updating datasets with wrong values.
Graphs can now get their title from a script, instead of
using a static string in hobbitgraph.cfg. This lets you
e.g. pick up the graphtitle from the mrtg.cfg.
All CGI's now pick up commandline options from a new
configuration file, hobbitcgi.cfg. This is to ease
packaging and make sure the CGI's can be updated without
losing local configurations.
The debian- and rpm-specific packaging files are now
included in the distribution tarfile.
A historical status-log now includes a "Full History"
button to go to the history overview.
"irix" is now recognized as operating system. A preliminary
vmstat RRD will be generated, but this may change in a
future version. "netstat" reports are not yet handled.
