### cURL JSON

`Collectd` comes with a wide range of metric aggregation plug-ins. Many tools today use [JSON](http://json.org) as data formating grammar; so does ArangoDB. Therefore a plug-in offering to fetch JSON documents via HTTP is the perfect match as an integration interface:

`Collectd` comes with a wide range of metric aggregation plug-ins.
|

Many tools today use [JSON](http://json.org) as data formatting grammar; so does ArangoDB.

Therefore a plug-in offering to fetch JSON documents via HTTP is the perfect match to query ArangoDBs [administrative Statistics interface](../../HTTP/AdministrationAndMonitoring/#read-the-statistics):

To circumvent the shortcoming of the curl_JSON plug-in to only take the last path element as name for the metric, we need to give them a name using our own `types.db` file in `/etc/collectd/collectd.conf.d/arangodb_types.db`:

|

# TypesDB "/usr/share/collectd/types.db" "/etc/collectd/my_types.db"
|
||||
|

in order to make it still load its main types definition file.
