This will remove cache entries that might have been computed during the lastconfiguration step.Compilation​Once properly configured, the compilation process is really simple:And wait until compilation completes.Install​Once compiled, the following command must be run as privileged user to finish installation:And wait for its completion.Configuration​Centreon Perl Connector itself does not require any configuration. It should only be configured as a connector ofCentreon Engine.To execute Perl scripts with Centreon Perl Connector from Centreon Engine, one might configure commands that relates toPerl scripts. Such commands must only contain the path to the Perl script to execute followed by its arguments, justlike one would on the command line. To make it simple, you just have to add a connector property to your commanddefinition.Binary arguments​These arguments are centreon_connector_perl options.Short nameLong nameDescription-d--debugIf this flag is specified, print all logs messages.-h--helpPrint help and exit.-v--versionPrint software version and exit.Example:define connector{ connector_name centreon_connector_perl connector_line /usr/bin/centreon-connector/centreon_connector_perl}define command{ command_name check_ping command_line $USER1$/check_ping.pl -H $HOSTADDRESS$ connector centreon_connector_perl}define command{ command_name check_disk command_line $USER1$/check_disk.pl -H $HOSTADDRESS$ -D $ARG1$ connector centreon_connector_perl}Technical details​This article describes how Centreon Perl Connector allow much gain on Perl script execution.First of all let's examine how a

You will need the following external dependencies:a C++ compilation environment.CMake (>= 2.8), a cross-platform build system.Centreon Clib, The centreon Core library.ssh2 library to use ssh functions.gcrypt library to secure connections.This program is compatible only with Unix-like platforms (Linux, FreeBSD, Solaris, ...).Prerequisites​CentOSDebian/UbuntuOpenSUSEIn CentOS you need to add manually cmake.
