Better integration with Centreon Engine and Centreon Broker¶
The installation process has been reviewed: it is now possible to specify the monitoring engine (Centreon Engine or Nagios) and the event broker module (Centreon Broker or NDOUtils). All you need to do right after a fresh installation is export your configuration files, then reload your monitoring engine and the monitoring system should be up and running!
This version offers the possibility to define the connectors for Centreon Engine. Obviously, you do not need to configure these connectors if you are still using Nagios.
It’s been said that Centreon Broker can be cumbersome to configure, especially if you are not familiar with its functioning. Centreon 2.4 offers a configuration wizard now!
This new page enables users to make their own views with various widgets and they are able to share their custom views with their colleagues!
See the user guide to learn more about this feature.
Support for multiple LDAP servers¶
The LDAP authentication system is much more robust than before. Indeed, it is now possible to have multiple LDAP configurations on top of the failover system. The LDAP import form will let you choose the LDAP server to import from.
Make sure that all your LDAP parameters are correctly imported after an upgrade.
New autologin mechanism¶
A better autologin mechanism has been introduced in this version. Now using randomly generated keys, it allows you to access specific pages without beeing prompted for a username and a password.
Communication with pollers¶
The default system user used by Centcore to communicate with pollers
has changed from
For better performances, we advise you to use
check_ping if you are in an IPv4 network, that is
(check_icmp is not yet compatible with IPv6). Switching from
check_icmp should be quite simple as the plugins take the same parameters.
All you have to do is change the check commands:
check_host_alive and all the commands that call
A new autologin mechanism has been added in Centreon 2.4. More secured than the previous one, it will soon replace it. If you currently use this feature, we recommend upgrading to the new one as soon as you can.
Centreon Broker init script¶
If you are using Centreon Broker, make sure to fill the Start script for broker daemon
Monitoring. RRD graphs cannot be rebuilt
if this parameter is omitted!
Two parameters have been added into the
Enable Perfdata Synchronisation (Centcore)
Enable Logs Synchronisation (Centcore)
For performance issues, these options must be disabled if your monitoring system is running with Centreon Broker.
Resource.cfg and CGI.cfg¶
The resource and CGI configuration objects are now specific to each monitoring poller. The values of $USERx$ macros can be different from one poller to another.
interval_length is now a global parameter that you have to set in
Monitoring, although it should be left at
60 seconds in most cases.
Supported data source types¶
Centreon Broker now supports all of the RRDtool data source types (COUNTER, GAUGE, DERIVE and ABSOLUTE). This support will not be added to Centstorage as it will soon be replaced by Centreon Broker.
See the Centreon Broker documentation to learn how you can convert your existing plugins.
