OpenNMS On the Horizon – CircleCI, Kafka, Time-Series API, Netflow, Minion, OIA

In the last week we kept working on CI improvements, fixed some Kafka bugs, fixed time-series and netflow issues, the new Minion-based remote poller infrastructure, OIA integration updates, and more!

Github Project Updates
