Collectd is a daemon which collects system performance statistics periodically and provides mechanisms to store the values in a variety of ways, for example in RRD files.

Sample pillars
==============

Send data over TCP to Graphite Carbon

.. code-block:: yaml

    collectd:
      client:
        enabled: true
        read_interval: 60
        backend:
          carbon:
            host: carbon1.comain.com
            port: 2003

Send data over AMQP

.. code-block:: yaml

    collectd:
      client:
        enabled: true
        read_interval: 60
        backend:
          amqp:
            host: broker1.comain.com
            port: 5672
            user: monitor
            password: amqp-pwd
           virtual_host: '/monitor'

Monitor network devices, defined in 'external' dictionary

.. code-block:: yaml

    external:
      network_device:
        MX80-01:
          community: test
          model: Juniper_MX80
          management: 
            address: 10.0.0.254
            port: fxp01
            engine: snmp/ssh
          interface:
            xe-0/0/0:
              description: MEMBER-OF-LACP-TO-QFX
              type: 802.3ad
              subinterface:
                xe-0/0/0.0:
                  description: MEMBER-OF-LACP-TO-QFX
    collectd:
      client:
        enabled: true
        ...

Collecting the SNMP metrics

.. code-block:: yaml

    collectd:
      client:
        data:
          connected_devices:
            type: devices
            values:
            - IF-MIB::ifNumber.0
        host:
          ubiquity:
            address: 10.0.0.1
            community: public
            version: 2
            data:
            - connected_devices
