[Announce] Monit 5.3

[Jan-Henrik Haukeland]

Hi, everyone!

We have just released Monit 5.3. You can download the new release from:

http://mmonit.com/monit/download/


Release information:
====================

This release includes two new great features; 

1) A new 'check program' statement was added to Monit. This allows
  Monit to check the exit status of an external program or script. 
  For example:

    check program myscript with path "/usr/local/bin/myscript.sh"
          if status != 0 then alert

  Here, myscript is executed by Monit and an alert is sent if the
  script does not return 0. The alert email will also include any
  (stderr) output made by the script.

  Please see 
http://mmonit.com/monit/documentation/monit.html#program_status_testing for a 
discussion on this new feature.


2) A new crontab style check has been added for individual services.
  You can now specify when an individual service should be checked 
  or, maybe more important, when a service should not be checked by
  Monit.

    Example 2: Check myscript every workday between 8AM and 7PM

    check program myscript with path "/usr/local/bin/myscript.sh"
       every "* 8-19 * * 1-5"

    Example 2: Do not check mysqld on Sundays between 0AM and 3AM

    check process mysqld with pidfile /var/run/mysqld.pid
       not every "* 0-3 * * 0"

  Please see http://mmonit.com/monit/documentation/monit.html#service_poll_time 
for more information on this feature.


Other improvements

* HTML view improvements

* Connection retry option added. Allows to retry a network
 connection in the same testing cycle before reporting an error.

* Detailed protocol connection errors are now included in alerts. 

* Changed the HTML overview page to display CPU and memory total
 (including children) so real service related usage is displayed also
 for services which spawn worker processes, such as Apache or
 Spamassassin.

* Fix MySQL protocol test: MySQL 5.5.12 returns new error code in
 the case of authentication failure.

* Fix Debian bug #621047: Monit fails to build after SSLv2 removal

* Fix crash on Solaris which may occur if the system load is zero.
 Thanks to Paul Sun for report.

* The stacktrace logging on error is disabled in -v (verbose) mode
 as it was too verbose for common service debugging tasks, it can
 be enabled using -vv option.

* Improve how fast Monit check if a program was started or stopped.
 Thanks to Michael Renner for patch. 

* Fix the monitoring state presentation during service restart which
 temporarily displayed "Not monitored", whereas the monitoring was
 enabled.

* The "data collected" is updated only if the check was not skipped.
