At Merethis, we all wanted to wish you a Happy New Year for 2013. The best way we found to thank you for supporting the Centreon project was to work hard over the Holidays Period to launch 3 new major versions of our main Open Source products including:
We would like to give credits to all our contributors, users and customers for this past year 2012 as it is thanks to them that we can keep growing bigger and bigger. All the MERETHIS team wish you and your family a Happy Holiday Season.
See you in 2013 for certainly an exceptional year !
This new version implements a key feature, the use of connectors. The main purpose of these daemons (programs that are run in background) is to provide better execution context to the check plugins. For instance: • SSH connector: this component is a connection multiplexer. It offers the reduction of open connections and it also makes them persistent • Perl connector : this component embeds a Perl interpreter and somewhat enhances the execution performances of plugins written in Perl The other noticeable features are the following: • Replacement of the Qt library by centreon-clib and libxerces (for the XML part) • A few fixes The detailed (technical) changelog is available at this URL : http://forge.centreon.com/versions/133
Release of Centreon Broker 2.2.1
This new version enhances overall performances thanks to the implementation of SQL transactions. Basically, the concept of these transactions is to group queries in order to generate less input/output on the server. When transactions are used, the executed queries affect a virtual copy of the database. It is only at the end of this operation that data is actually written in the disk and made accessible to users. This mechanism highly enhances the input/output situation of the storage device.
The other noticeable features are the following: • Non-process of host/service statuses that are too old (next_check < now) • New statistics module for retrieving information such as the list of loaded modules, processing speed, connection status, etc… • Deactivation of the SIGCHLD signal (less back and forth signals between kernel-space and user-space) • Rotation of log files (for limiting storage issues) • Possibility to write cbmod logs directly in the Centreon Engine/Nagios logs • Possibility to disable log synchronization on the disk (*sync* system calls) • Stalled callbacks with Centreon Engine/Nagios (lesser restarting time) The detailed (technical) changelog is available at this URL:http://forge.centreon.com/projects/centreon-broker/versions/160
The Centreon CLAPI module (Centreon Command Line API) is a tool to manage all configuration of Centreon server objects’. Using command line from a terminal, it’s possible to add/modify/delete configuration objects of the scheduler (Hosts, Services, contacts, Groups, etc.), the access control list (ACL) of Centreon GUI or manage schedulers and brokers.
