Unit 5 Discussion: Using Linux Log Files to Troubleshoot a System

45 unread replies.70 replies.

Linux operating systems generate and capture messages in log files for most of the elements of the operating system whenever there is a system event like a command is entered at the command line, or a daemons starts, and when any service runs. One of these new logs is called the journald.

The tasks of the administrator is to use these log files to determine why a service or process did not work correctly.

In your discussion post: make a list of different ways to use the log files in troubleshooting problems with a Linux system.

  • Visit several sites listed below and compile a list of five (5) methodologies that help troubleshoot a Linux system. Try to select different ways than that of your peers have not already posted.
  • Describe each of the five methods and provide a screenshot or description of each. You may need to search the public web using a search engine like Google or Bing to find screenshots of systems with different services. Cite any sources you use in APA format; this includes sources for any screenshots that are not your own.
  • When responding to your peers’ posts, describe your initial thoughts on the best advantage over the other systems’ services they posted. Note any major similarities or differences your notice between the different services.
