Using Apama with Prometheus and Grafana

In Apama 10.3 we released integration for Apama with the popular Prometheus monitoring framework. These metrics can then be easily visualized using tools such as Grafana. Apama has had the capability to be monitored via HTTP REST interfaces on Apama correlators for a number of releases now. With Apama 10.3 we added REST endpoints to the correlator that align with the specification used by Prometheus.  All of the metrics exposed are of type Counter or Gauge.… Read More

Python Plugins – Using scikit-learn for Outlier Detection

Machine learning is becoming ever more useful in data processing, and with Apama’s new Python plug-in capability it is now even easier to use this from within EPL. There are various machine learning libraries available for use, such as TensorFlow and scikit-learn. We’ve chosen to create this demo using scikit-learn, as an example of outlier detection using this library already exists. We’ll be basing this demo on the example (found here).… Read More

Build, test and deploy Apama projects using the Apama Builder Image


There’s a new Docker image in the Docker Store for Software AG’s 10.3 release called Apama Builder. It differs from the Apama Correlator image in that it can be used to build Apama projects into new images via multi-stage builds. In this blog we will explore how leveraging the Apama Builder along with other common tools, we can easily create an Apama application in a container that is self-testing, self-deploying, and subject to continuous integration.… Read More

Python Plug-ins

Following on from the blog post introducing the new Apama EPL Python plug-ins feature, we provide a video that will give you a good insight into developing a Software AG Designer project using the Python plug-ins feature in Apama.

The video goes into detail about how to set up a new project and use Python plug-in methods from EPL code.

PyDev Install PyDev

The video also shows you how to set up PyDev, which is a Python IDE for Eclipse and can be used for programming in Python – supporting code refactoring, graphical debugging and code analysis among other features.… Read More

Introduction to Python Plug-ins

In Apama 10.3 we introduced a new way to create extensions to EPL (the Apama language). In addition to writing extension points (plug-ins) to EPL in C++ and Java, it is now possible to also create them in Python.

The new interface to Python is a fully-fledged mapping between EPL and Python types allowing you to expose Python methods to be called directly from EPL with complex type arguments returning values and throwing exceptions directly back to EPL.… Read More
