What’s new in FlexLM 11.12 debug logs

The FlexLM license manager produces Debug log files, which hold status information and error messages that are useful for debugging its activity. In version 11.12 Flexera added a few changes to the Debug logs; namely a set of global information entries that relate to the lmgrd daemon and to specific vendor daemons. These are referred to as SLOG: Summary Log statistics.

SLOG for lmgrd

SLOG entries for the lmgrd daemon are prefixed by (@lmgrd-SLOG@).

These include:

  • Start timestamp
  • Version
  • ProcessID
  • Network Info (IPv4/IPv6 interface, License manager port)
  • Command-line options
  • list of license files
  • Is the license server running as a Windows’ service.

Example from an actual debug log file:


7:47:03 (lmgrd) SLOG: Summary LOG statistics is enabled.

SLOG for vendor daemons

Debug logs may be split and redirected according to Vendor daemons. This facilitates zooming in on vendor specific data. Vendor daemon specific SLOG entries are prefixed by (@<vendor>-SLOG@). These include:

  • Start timestamp
  • Version
  • ProcessID
  • Network info (IPv4/IPv6 interface, listening port, select timeout of vendor daemon)
  • Vendor daemon name
  • Options file used
  • Trusted storage accessed (yes/no)
  • Host name
  • Virtual/physical environment
  • (limited) Hypervisor info if virtual
  • Lmbind used (yes/no)
  • Number of restarts of the Vendor daemon since lmgrd startup
  • Number of rereads since vendor daemon was started (or restarted)
  • Last reread time
  • Reread initiation type (automatic versus lmreread).

Every 4 hours (and at vendor daemon shutdown) the following performance data entries are also logged:

  • Details of the 10 peak client transactions (including client hostname, user, transaction time, concurrent clients at time of transaction, memory usage (Windows only))
  • Peak concurrent clients served
  • High watermark memory usage (for Windows only)
  • Transaction time for the last 10 transactions.

OpenLM makes use of the information in the debug log to accumulate and refine the license usage and license denial statistical data.
