Transforming Commands of Splunk.

The search must transform the event data into statistical data tables to create visualizations of the charts. These statistical tables are required for the visualization of charts and other kinds of data. In this section, we will explain how to use transform commands to extract data from events. Splunk architect certification has a thorough understanding of Splunk Deployment Methodology and best practices for planning, and data collection, and sizing for a distributed deployment and is able to manage and troubleshoot a standard distributed deployment with indexer and search head clustering.

It will provide a piece of brief information on transforming commands and search for more information about transforming commands and their role in creating statistical tables and chart visualizations.

TransformingA transforming command commands the results of the search to a table of data. Such commands "transform" the specified cell values for each event into numerical values, which can be used for statistical purposes by Splunk software. Transforming commands are also necessary to transform the search result data into the data structures required for visualizations such as column, bar, line, area, and pie charts.

If used to measure column totals (not row totals), transforming commands include a map, timecard, details, top, uncommon, and add totals.

Our search must transform the event data into statistical data tables to create visualizations of the charts. These statistical tables are needed for the visualization of charts and other kinds of data. Here we will learn how to use the transform commands to extract data from events.

Transforming commands

The primary transforming commands are:

-charts: Build charts that can show any data series you wish to plot. On the ----chart's x-axis, you can determine which field is tracked.-time chart: Used to create reports about "trend over time," which means that time is always on the x-axis.-top: Generates charts that show the most common field values.-Re rare: Create charts that display the least common field values.-stats: Produces a report displaying summary statistics

The commands Chart, Timechart, and Stats are all intended to work with statistical functions. The list of statistical functions available are:

-count, distinct count-mean, median, mode-min, max, range, percentiles-standard deviation, variance-sum-the first occurrence, last occurrence

Some statistical functions only work with the time chart command.
