[Check-multi-announce] Stable check_multi 0.26 is released

[Matthias F. <mat...@gm...>]

====== check_multi stable 0.26 released ======


It's urgent time for the next release, for some new features and for
plenty of bug fixes.

=== Features ===

  * 'attribute [ <TAG>::<variable> ] = <expression>'

This feature is mightier than you expect. In some extent it works like
http://www.my-plugin.de/wiki/projects/check_generic/start check_generic
does.

It can set child specific variables, such as process_perfdata, timeout
or displayed.
But you also can set attributes like critical, warning, and unknown, and
this is pretty much the same as you specify 'state [ critical ] =
<expression>', just on the child check level. It will be evaluated
directly after a child check has been executed and affects the state of
a particular child check.

Let me give an example:
> command   [ tmp_dir_permissions           ] = ls -ld /tmp
> attribute [ tmp_dir_permissions::critical ] = $tmp_dir_permissions$ !~ /^drwxrwxrwt/</

The output is:
> $ check_multi -f test_tmp_dir.cmd -r 1+4+64
> CRITICAL - 1 plugins checked, 1 critical (tmp_dir_permissions)
> [ 1] tmp_dir_permissions CRITICAL drwxr-xr-x 10 root root 4096 Nov 17 15:29 /tmp [CRITICAL: output matched rule '"$tmp_dir_permissions$" !~ /^drwxrwxrwt/']</code>

  * 'attribute [ <variable> ] = <value>

This is an option if you want to specify all in your cmd files to not
use command line parameters like '-s <variable>=<value>'. Any -s option
can be added with this attribute statement.

=== Other changes and fixes ===

   * Macros
     * FIX: macro handling for livestatus command
     * FIX: macro handling: complain about non-existing macros and remove

   * Output
     * print matching state rule in long plugin output
     * provide error message if no HOSTNAME is specified for passive
service definitions

   * Tags
     * Note: spaces in tags and macros are not allowed any more to
prevent ambiguities
     * numerical tags are not allowed

   * Performance data
     * added perfdata for statusdat command
     * FIX: perfdata column for livestatus command
     * FIX: hostname treatment for PNP urls
     * FIX: cumulate perfdata handling
     * better perfdata error output for invalid UOM

   * XML output
     * inventory parameter: reduced XML for feed_passive (no execution,
only output)
     * FIX: encoding of XML state elements

   * Miscellaneous
     * FIX: handling of non existing child state rules
     * child timeout increased to 11s - no collision with 10s default
     * FIX: trimming blanks at line end with continuation lines
     * statusdat checks now only consider hard states
     * feed_passive with perfdata [ plugin ] at the end
     * contrib: notify_html_service.sh uses mime multipart elements
     * FIX: verbose mode

Have fun with check_multi,
