In preparation for using KPI Management in MediationZone, a number of scripts need to be extracted and some setup is required. This is described on this page.
...
These scripts will be used for different procedures that you find in the sections for KPI Management - Distributed Processing.
Preparations before extracting scripts:
A Prerequisite is that Spark, ZooKeeper, and Kafka are installed. Zookeeper and Kafka should be up and running as well. For more information about this, see LINK needed
Before running the command to extract the scripts, these parameters need to be set as environment variables as they will be entered into some scripts:
...
1. Set up your preferred KPI profile or use the simplified example configuration which can be found in kpi_tst.zip ← Where can we find this?
2. Find and the kpi_spark*.mzp among the installation files and copy it to a place you want to keep your KPI application files.
...
Here all that needs to be changed is the master host ip, as well as the ports if needed. ← I don’t know what SPARK_LOCAL_IP is used for.
Edit the kpiapp/bin/spark_common_param.sh, so it has the SPARK_HOME path.

Prerequisite Before you continue: Spark applications must be configured with a set of Kafka topics that are either shared between multiple applications or dedicated to specific applications. The assigned topics must be created before you submit an application to the Spark service. Before you can create the topics you must start the Kafka and Zookeeper services. An example order of topics are the following: kpi-input - For sending data to Spark kpi-output - For spark to write the output to, and thus back to the workflow kpi-alarm - For errors from Spark |
