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
