KHIKA Reports

Introduction

Some reporting requirements demand processing of the indexed data further using some high level programming language. The processed output can then be stored again into the “_rpt” index and visualizations and dashboards can be created on it. Essentially, reports are the programs or scripts that take indexed data from KHIKA as input and further process it to generate desired output. They can be scheduled to run daily or weekly or at a custom time.

Typically, a Report searches for specific data already indexed in the system. Each report is meant for that specific purpose. It is associated with a specific “lucene” query and a program capable of processing the output of the lucene query. KHIKA runs the query associated with the Report at scheduled time to filter the data from indexed data and presents the output to the program/script associated with the Report on its “stdin” in the CSV format. The program written in a high level programming language can implement any complex logic to perform computations on this data and create meaningful output in the CSV format. The program must write its output on its “stdout”. KHIKA consumes this output and stores it back in the “_rpt” index.

The data from the “_rpt” index can be used for visualization and dashboards.

Go to Configure – Reports. Select the workspace from the workspace dropdown. You can see all the reports present in that workspace.
