Project:

• Built a performance monitoring system that ingests and processes machine logs and generates intuitive visualizations at the real time according to the user configuration.

• A web-based application is composed of uploading logs, authoring tool, and graph explorer.

• Uploading log is used to store the logs data into the database.

• Authoring Tool is used to configuring the data flow using available nodes in Node-Red. The user can create its own complex data flow.

• Graph Explorer is used to visualize the data according to the configuration during the selected time range.

• Very useful and intuitive system for the workers to visualize the processing of their machine. Such tools can be used in the wide range of industries.

Architecture:

• The big data is getting processed, structured using Java engine and indexed in ElasticSearch / Solr.

• The processing engine is used to process the configuration along with searching data in the database to generate various charts as per the requirement.

• Generation of rules dynamically and applies rules for states of the machine. Predicts defects in the machine using Spark MLlib.
