#### MODULOS implementados en Pandora
##########################################################################
# ----------------------------------------+
# Modulos genericos de Pandora |
# ----------------------------------------+
# Los modulos genericos de pandora son de 4 tipos
#
# generic_data . Almacena numeros enteros largos, util para monitorizar proceos que
# general valores o sensores que devuelven valores.
# generic_proc . Almacena informacion booleana (cierto/false), util para monitorizar
# procesos logicos.
# generic_data_inc . Almacena datos igual que generic_data pero tiene una logica
# que sirve para las fuentes de datos que alimentan el agente con datos
# que se incrementan continuamente, por ejemplo, los contadores de valores
# en las MIB de los adaptadores de red, las entradas de cierto tipo en
# un log o el nº de segundos que ha pasado desde X momento. Cuando el valor
# es mejor que el anterior o es 0, se gestiona adecuadamente el cambio.
# generic_data_string. Store a string, max 255 chars.
