Learn to debug issues, as well as provide statistics on the live machine.
- [Instructor] Welcome to the next video of section eight,…Logfile Management with logrotate.…In the previous video, we have learned…about logging access to files and directories.…In this video, we're going to see how…to rotate logs and store them.…Logfiles are essential components of a Linux system…to keep track of events happening…on different services on the system.…This helps to debug issues…as well as provide statistics on the live machine.…Management of logfiles is required because, as time passes,…the size of a logfile gets bigger and bigger.…
Therefore, we use techniques called rotation,…such that we limit the size of the logfile,…and if the logfile reaches a size beyond the limit,…it will strip the logfile with that size…and store the older entries in the logfile archived…in log directories.…Hence, older logs can be stored…and kept for future references.…Logrotate is a command every Linux system admin should know.…It helps restrict the size of the logfile to the given size.…In a logfile, the logger appends information to the logfile.…
