Collecting Performance Parameters with respect to Activities and Processes

It is important to identify activity instances and process instances with respect to time and memory.

1. Set the following configuration properties in the analyzer_config.ini file stored at <BWCE_HOME>\bwce\2.x\config\analyzer_config.ini.

   Property	Description
   bw.analyzer.db.create.schema	Create tables on startup if not exists. The default value is true.
   bw.analyzer.data.interval	Set the value in minutes, hours, or in days. For example: bw.analyzer.data.interval=15days. The default value is not set. If the property is not set the query is executed on the complete data.
   bw.analyzer.refresh.interval	Refresh interval for memory cache. The default value is 60000 milliseconds.
   bw.analyzer.udp.host	Optional. Set the UDP server host address. The default value is localhost.
   bw.analyzer.udp.port	Optional. Set the UDP server listening port. The default value is 34567.
   bw.analyzer.db.driver	org.postgresql.Driver Currently only the PostgreSQL database is supported.
   bw.analyzer.db.connectionURL	Set the database connection URL. The default value is jdbc:postgresql://localhost:5432/analyzer
   bw.analyzer.db.userName	Set the database username. The default value is postgres.
   bw.analyzer.db.password	Set the database password. The default value is admin.
   bw.analyzer.log.level	Set the root log level. The default value is info.
   bw.analyzer.jetty.server.port	Set jetty server port. The default value is 8080.

2. Configure the database details in analyzer_config.ini file and copy the file to <BWCE_HOME>/bwce/2.x/system/analyzer/ folder. Create the docker image and analyzer instance with docker file present under <BWCE_HOME>/bwce/2.x/system/analyzer/Dockerfile
3. Set the BW_ANALYZER_CONFIG= <UDP server Host>:<UDP server Port> environment variable while running the application.
   This property starts sending the activity instance and process instance data from Container.

   Set the following properties in the Container's BW_JAVA_OPTS environment variable while running the application:

   Property	Description
   bw.engine.analyzer.udp.host	Optional. Set UDP server hostname or an IP value. The default value is localhost.
   bw.engine.analyzer.udp.port	Optional. Set UDP server listener port value. The default value is 34567.
   bw.engine.analyzer.batchsize	Optional. Set the threshold value for activity or process instances to analyze the data in one batch. The default value is 100.
   bw.engine.analyzer.publishtimer	Optional. Set subscriber publisher time interval in milliseconds. The default value is 30000.

4. Use REST APIs to interact with the data using Swagger UI at URL http://<hostname/IP>:<PORT>/.
   Note: Base path for all REST APIs exposed is http://<host or IP address>:<port>/api/
