Meet the project team leads for these new projects and learn how to get involved.

OpenStack’s big tent has expanded to house new projects: Monasca, Senlin, Fuel, Freezer
and Winstackers. In this series of posts, we’ll give you a quick overview of these projects, introduce you to the project team leads (PTLs) and find out what they’re looking for from the community.

Monasca

What: Monasca is a multi-tenant, highly scalable, performant, fault-tolerant monitoring-as-a-service solution for metrics, complex event processing and logging.

Who: Roland Hochmuth, PTL, is a software architect for Hewlett-Packard Cloud.

What new features/enhancements/fixes are expected for the Mitaka release?
There are a number of new features that are focused on improving the performance of user-interfaces by reducing the amount of client-side processing that needs to be done.

What contributions do you need most from the community?
One of organizations that is deploying Monasca is really starting to push the boundaries of monitoring-as-a-serice. There are several improvements to the API that we believe could significantly improve performance. One area that seems really compelling though is to develop an in-memory time-series cache for the hot metrics, similar to what Facebook has implemented: http://www.vldb.org/pvldb/vol8/p1816-teller.pdf.
If developers are interested in working in this area, it would be a pretty exciting way to get in on the ground floor.

Senlin

What: Senlin is a clustering service designed for managing homogeneous objects exposed by any other OpenStack services. It features an open framework where developers can provide plugins for specifying the type of objects to be managed and the policies they want to enforce when certain cluster operations are performed. In short, it provides an array data type for programming/managing an OpenStack cloud. The name means "forest" in Mandarin.

Who: Qi Ming Teng, PTL, is a research scientist at IBM.

What new features/enhancements/fixes are expected for the Mitaka release?
Senlin joined the OpenStack big tent during the Mitaka cycle. As a new project, the first priority for the development team is about the API specification and the stability of the service engine. Instead of delivering many fancy features to draw attention from the community, the team has chosen to focus more on making the initial release usable. The rationale behind the decision is that we can always add new features, but we will never get a chance to deprecate things we do wrong in the beginning.

In the first official release, Senlin will provide the following features:

  • basic management of profiles, clusters, nodes and policies
  • sample policies such as deletion, placement, scaling and load-balancing
  • binding policies to clusters
  • basic support to receivers (the only type would be webhook)

What contributions do you need most from the community?
Most of Senlin’s developers are from China, behind a national firewall that blocks us from accessing any social media. The team has difficulties in advertising this technology to a broader audience.

Another thing we may need help with is to raise awareness of other projects which can consume Senlin. One is Sahara, which can use Senlin to manage the VM provisionings. Another is Magnum, also can use Senlin for provisioning VMs. The advantage of using Senlin to do this is that Senlin gives the requester more knobs to control the clusters they want to manage. Using Heat for these tasks has proved to be very inconvenient.
