Container /Cadvisor Support

Looking at integrating with Prometheus.

Investigating events support.

    
Process MonitoringDesign ReadyAdd a method which will accept a userspace process name as a parameter and return its pid   
OVS with DPDK PMD statsMerged to barometer repoCreating a script that will pull OVS-with-dpdk PMD stats and publish them to collectd. these stats are not retrievable through the OVSDB - but should be in the future - which is why this integration is stand alone for now   
OVS Multi Instance Support

Pull request created:

https://github.com/maryamtahhan/collectd/tree/feat_ovs_multi_instance

VES Kafka integrationSeparate out VES collectd application from collectd so that it can be apache licensed, and use a kafka bus to send info from collectd to this VES collector...     
VES configuration through a schemaUnder internal review    
Event-based, interface monitorPull Request created: https://github.com/collectd/collectd/pull/2407This plugin monitors an ethernet interface or group of ethernet interfaces and reports link status changes. The plugin does not poll for link status but rather recieves status events eliminating the polling overhead. Detection times vary by device driver, but typical detection times are below 10ms.
