This new design of syslog allows for an easy implementation of input and output modules. The modules that mantain compatibility with its precursor (Secure Syslog) are included in the standard distribution along with four modules: om_peo (an implementation of PEO-1 and L-PEO, two algorithmic protocols for integrity checking), om_mysql and om_pgsql (modules that sends output to a MySQL and PostgreSQL database, respectively) and om_regex (a module that allows output redirection using regular expressions).
