Hello,

This is a proposal.

Actually it's not possible to add types without a specific configuration without change $collect::typesdb param. (or I've miss something maybe ?)

With this feature you can have:

cat typesdb.conf 
TypesDB "/usr/share/collectd/types.db"
TypesDB "/etc/collectd/collectd.d/dbi_mysql.typesdb"

with a single declaration

  collectd::typesdb { 'typedb_mysql':
    path    => "${collectd::config_dir}/dbi_mysql.typesdb",
    include => true,
  }

Pull Request (PR) description

This feature is available only if $collectd::purge_config is set at true

• Add an include of <collectd_dir>/typesdb.conf in the collectd.conf
• Create a concat resource for <collectd_dir>/typesdb.conf
• Move $collectd::config::typesdb on the <collectd_dir>/typesdb.conf
  file
• Add include param to collectd::typesdb, for dynamic addition on typesdb.conf

This Pull Request (PR) fixes the following issues
