In preparation for using KPI Management in MediationZone, you need to extract the following scripts:
...
These scripts will be used for different procedures in the KPI Management - Distributed Processing sections.
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 KPI Management - External Software.
...
Extracting scripts and KPI app:
| Rw ui steps macro |
|---|
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? Find the kpi_spark*.mzp among the installation files and copy it to where you want to keep your KPI application files. To extract the KPI app after building it run the following command. It extracts the software needed by spark for the KPI app as well as the scripts needed for starting and configuring spark. | Code Block |
|---|
$ cd release/packages
$ java -jar kpi_spark_9.1.0.0.mzp install |
|
...
You will find the new directory mz_kpiapp that contains all app software. | Code Block |
|---|
$ ls -l mz_kpiapp/, will list:
app # The MZ kpi app
bin # Shell script to handle the app
jars # Extra jar files for the app |
|
...
Move the mz_kpiapp folder and add it to the PATH. | Code Block |
|---|
Example:
$ mv mz_kpiapp ~/
$ export PATH=$PATH:/home/user/mz_kpiapp/bin |
|
...
Set the environment variable SPARK_HOME. | Code Block |
|---|
$ export SPARK_HOME="your spark home" |
|
...
The next step is to modify the scripts under the bin folder according to your specifications and requirements, as they are when extracted they are to be considered as more of examples than a finished configuration. The scripts kpi_params.sh and spark_common_params.sh are the ones that need to be updated. In kpi_params.sh, KAFKA_BROKERS need to be configured with the hosts and ports of the kafka brokers. For example: export KAFKA_BROKERS="192.168.1.100:9092,192.168.1.101:9092,192.168.1.102:9092"
The username and password for a user with access to the profile is needed to be entered as the property MZ_PLATFORM_AUTH, unless the default username and password mzadmin/dr is used. The password is encrypted using the mzsh command encryptpassword. |
...
The memory settings may need to be altered depending on the expected load, as well as the UI port for the KPI App inside Spark (default 4040).
In addition to the addresses and ports of the platform, kafka and zookeeper may need to be updated.
In spark_common_params.sh, you may need to change the master host IP and ports if applicable. Edit the kpiapp/bin/spark_common_param.sh, so it has the SPARK_HOME path. Access the conf-folder of Apache Spark, the spark-defaults.conf.template file should be renamed to spark-defaults.conf and the following configuration variables and options added: | Code Block |

Add this to the jvmargs section of the execution context definition for the ec that will run the KPI Management workflows. For example:
You can open the configuration by running: |
mzsh mzadmin/<password> topo open kpi_ec
