Issue/Introduction

The following are the instructions for configuring the TrapExploder LogRotate functionality.

LogRotate is used to create a new log file every day, archive (compress) the previous day’s file and retain a specific number of archives (365 in this example).

This function provides an easy maintenance mechanism that also makes searching the current day or previous day’s logs easier. Without this function, a single huge file would be continuously appended to until all disk space was consumed.

Environment

TrapExploder running on Linux
