Titan Control Center - Aggregation

The Titan Control Center is a scalable monitoring infrastructure for Industrial DevOps. It allows to monitor, analyze and visualize the electrical power consumption of devices and machines in industrial production environments.

This repository contains the Aggregation microservice of the Titan Control Center.

Configuration

This microservice can be configured via environment variables or a Java application.properties file. Most variables are self explaining.

• EMIT_PERIOD_MS determines the frequency aggregation results are generated with. It has to be set at least as large as the period sensors are generating measurements with. If a sensor is generating no measurement withing an emit period, the corresponding aggregation result would not contain a value from the corresponding sensor and, thus, would be lower than it should be normally.
• GRACE_PERIOD_MS dertermines for long late arriving measurements are considered and, thus, for how long they would cause corrective aggregation results.

Build and Run

We use Gradle as a build tool. In order to build the executeables run ./gradlew build on Linux/macOS or ./gradlew.bat build on Windows. This will create the file build/distributions/titanccp-aggregation.tar which contains start scripts for Linux/macOS and Windows.

This repository also contains a Dockerfile. Run docker build -t titan-ccp-aggregation . to create a container from it (after building it with Gradle).
