How to use memcached server for retention datas ?
-------------------------------------------------
Some plugins need to store datas. Two ways to store it:
* File on a disk (by default)
* Memcached server
To use 'memcached', you must have a memcached server and the CPAN 'Memcached::libmemcached' module installed.
You can set the memcached server with the option ``--memcached``:
::
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --mode=traffic --hostname=127.0.0.1 --snmp-version=2c --snmp-community=public --verbose --skip --skip-speed0 --memcached=127.0.0.1
OK: All traffic are ok | 'traffic_in_lo'=197.40b/s;;;0;10000000 'traffic_out_lo'=197.40b/s;;;0;10000000 'traffic_in_eth0'=14539.11b/s;;;0;1000000000 'traffic_out_eth0'=399.59b/s;;;0;1000000000 'traffic_in_eth1'=13883.82b/s;;;0;1000000000 'traffic_out_eth1'=1688.66b/s;;;0;1000000000
Interface 'lo' Traffic In : 197.40b/s (0.00 %), Out : 197.40b/s (0.00 %)
Interface 'eth0' Traffic In : 14.54Kb/s (0.00 %), Out : 399.59b/s (0.00 %)
Interface 'eth1' Traffic In : 13.88Kb/s (0.00 %), Out : 1.69Kb/s (0.00 %)
.. tip::
Local file is used if the memcached server is not responding.
------------------------------------
What does ``--dyn-mode`` option do ?
------------------------------------
With the option, you can used a mode with a plugin. It commonly used for database checks.
For example, i have an application which stores some monitoring information on a database. The developer can use another plugin to create the check (no need to do the SQL connections,... It saves time):
::
$ perl centreon_plugins.pl --plugin=database::mysql::plugin --dyn-mode=apps::centreon::mysql::mode::pollerdelay --host=10.30.3.75 --username='test' --password='testpw' --verbose
OK: All poller delay for last update are ok | 'delay_Central'=2s;0:300;0:600;0; 'delay_Poller-Engine'=2s;0:300;0:600;0;
Delay for last update of Central is 2 seconds
Delay for last update of Poller-Engine is 2 seconds
.. warning::
A mode using the following system must notice it (in the help description). So you should open the file with an editor and read at the end the description.

@ -433,3 +471,15 @@ Some plugins need to set the option ``--custommode``. You can know the value to
$ perl centreon_plugins.pl --plugin=storage::ibm::DS3000::cli::plugin --custommode=smcli --list-mode
I get the error: "UNKNOWN: Cannot write statefile .*"
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
You must create the directory (with write permissions) to let the plugin stores some datas on disk.
I get the error: "UNKNOWN: Cannot load module 'xxx'."
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The problem can be:
* A prerequisite cpan module is missing. You need to install it
* The cpan module cannot be loaded because of its path. Perl modules must be installed on some specific paths
