  • Hello,

    You'll find the log files in

    /var/log
    folder. Two main files worth checking are
    /var/log/ltm
    and
    /var/log/tmm
    . Use the Linux program "less" in combination with "grep" (line-search functions) to work with the log files. By default, those log files cover a 1 week period. This can be modified. The log files from previous days have the file extension ".gz", you don't have to unpack them, the "less" program can read those too.

      1. Yes, this folder and subfolders in it contain all the log files. There are no other places you need to know about. 2. /var/log/ltm reports all the operational LTM events, such as Pool UP/DOWN but also hardware issues such as symptoms of system overheating, or hard drive errors. /var/log/tmm reports microkernel events such as global system crashes and the file is usually empty. If your system crashes due to a tmm error, it's quite likely the root cause will be logged here. 3. e.g. "less /var/log/ltm". Perhaps this article will help you to get started with working with the log files: https://support.f5.com/kb/en-us/solutions/public/16000/100/sol16197.html Good luck!
