MoNanas - Monasca Analytics Framework

Overview

Monasca Analytics (MoNanas) is a statistical/machine-learning (SML) flow composition engine. Users can compose a sequence of algorithms to be executed by just providing a description as an input to MoNanas. The data flow is automatically handled by the framework.

Easy flow composition and reusability means that we can speed up the extraction of actionable infrastructure insight.

Advantages

👍 Decouple algorithm design from execution.

👍 Reusable specification of the desired flow.

👍 Language independent flow definition.

👍 Data source and format independent.

👍 Easy to add new SML algorithms and # combine them with pre-existing ones in the flow.

👍 Transparently exploit data parallelism.

Example Use Cases

Below are few use cases that are relevant to OpenStack. However, MoNanas enables you to add your own data ingestors.

Example	Alert Fatigue Management	Anomaly Detection
Dataset	Synthetic, but representative, set of Monasca alerts that are processed in a stream manner. This alert set represents alerts that are seen in a data center consisting of several racks, enclosures and nodes.	iptables rules together with the number of times they are fired in a time period.
Parsing	Monasca alert parser.	Simple parser extracting period and number of fire events per rule.
SML algorithm flow	filter(bad_formatted) -> filter(duplicates) -> aggregate() >> aggregator aggregation can utilize conditional independence causality, score-based causality, linear algebra causality.	detect_anomaly() >> aggregator anomaly detection could be based on SVM, trend, etc.
Output	Directed acyclic alert graph with potential root causes at the top.	Rule set with an anomalous number of firing times in a time period.
ℹ️ Note	Even though this could be consumed directly by devops, the usage of Vitrage MoNanas Sink is recommended. The output of this module can speed up creation of a Vitrage entity graph to do further analysis on it.	None.

-> indicates a sequential operation in the flow.

// indicates beginning of group of operations running in parallel.

- indicates operations running in parallel.

>> indicates end of group of operations running in parallel.

MoNanas Design

See: MoNanas/Design for details on MoNanas's architecture, its functional requirements and core concepts.

Technologies

MoNanas uses a number of third-party technologies:

• Apache Spark (http://spark.apache.org/): Apache Spark is a fast and general engine for large-scale data processing.
• Apache Kafka (http://kafka.apache.org/): Used by Monasca and MoNanas's Kafka source and sink.
• Apache ZooKeeper (https://zookeeper.apache.org/): Used by Kafka.

Feature Release Schedule

• Basic SML flow.
• New algorithm "add-on" ability.
• Example datasets and SML flows.
• Support end-to-end learning + data processing flows (currently, the latter part does not get updated due to Spark's immutability.)
• Refactor codes to be consistent with terms used in the documentation.
• Add a source, ingestor and transformer for Monasca.
• Model connections as objects rather than references and have driver specifics in one place.
• Expanded orchestration abilities/expressiveness.
• Container-enabled testing/deployment for non-production environments.
• Add Vitrage Sink.
• Add a ready-to-use virtual machine image (get rid of the fetch-deps.sh).

Contributing

There are multiple ways to contribute to the project. All are equally important to us!

• You can have a look at the Monasca launchpad for problems that needs to be solved (bugs/issues), and blueprints.
• You can also help us to add new learning algorithms.
• Finally, we are very interested in having more data sources to experiment with. The source can either be from an existing data provider or randomly generated. The more, the better! :) If you are interested to work on that aspect, you are welcome as well.
