The simulation.log file is an internal and is only meant to be parsed by the module that generates the HTML reports.
Format is subject to changes without further notice.

So it means that we cannot modify the format of the simulation.log file.
In that case please help me how I can write the variable value in a text file.

Use below code for writing your customized data into output steam.

val writer = {
val fos = new java.io.FileOutputStream("/gatling/bin/ErrorOutput.txt")
new java.io.PrintWriter(fos,true)
}
