Plugin to monitor ArangoDB servers. It works with the new server statistics
interface of ArangoDB 1.3. Not every value seems senseful, but there are
nice graphs generated...

Usage:
- Link or copy to /etc/munin/plugins
- To enable extra graphs, also link to one or more of the
possible links (given below)
- Then restart munin-node
Links possible:
arangodb_conn HTTP client connections
arangodb_time_total Total request/queue/connection time
arangodb_bytes_total Total sent/received bytes
Configuration:
- No configuration required. Just enable the admin interface of ArangoDB.
Thanks to the authors of other Python munin plugins. I've used some of
them as inspiring example.
Possible todos:
- support of munin-like configuration parameters
- add more statistics
