The log size is over 7 GB and Linux is having an issue compressing it.


All LEM versions


  • ASA, for example, can generate up to 6 GB of syslog an hour if info severity is enabled.
  • In 24 hours that log can easily exceed 8 GB.
  • The Log file is exceeding 8 GB and LEM is set to compress compresses the log files daily.
  • Linux cannot compress files over 8 GB.


  1. Change the default values on the LEM by going to the CMC shell in Vsphere or putty.
  2. In the command prompt, enter the command appliance.
  3. Enter the command setlogrotate and change to hourly. This allows LEM to compress a file each hour instead of daily.
    Note: If your Logs/Data partition is full or a particular Syslog file is large, contact SolarWinds Support to assist in this process.
