FLEXnet Licensing End User Guide 139
Appendix FThe Report Log File F
The license server system produces both report log files and debug log files. The focus of this
appendix is report log files. For information on debug log files see Appendix G, “The Debug
Log File.”
The report log file contains feature usage information and is generated by the vendor daemon.
However, a vendor daemon does not write report logs by default; this action must be enabled.
The data in report logs is compressed,authenticated and organized into a respository.
Use Macrovision's software license administration solution, FLEXnet Manager, to gain
exceptional visibility into license usage data and to create insightful reports on critical
information like license availability and usage. FLEXnet Manager can be fully automated to run
these reports on schedule and can be used to track license servers and usage across a
heterogeneous network of server including Windows NT, Linux and UNIX. Contact
Macrovision at www.macrovision.com for more details on how to obtain an evaluation copy of
FLEXnet Manager for your enterprise.
Managing Report Log Output
As a vendor daemon runs for a period of time, the volume of report log output increases. If you
have a lot of license activity, these log files grow very large. You need to consider where to put
these files and how often to rotate and archive them. Therefore, it may be necessary to rotate or
switch report log output into different files over time, each file containing license activity over
a particular period of time.
Report log data is collected by the vendor daemon into an internal data buffer area before being
flushed to the output file. The daemon’s internal buffer is flushed once a minute or whenever it
gets full, whichever occurs first. To ensure the freshest data possible in the report log file, flush
the buffer on demand with the
lmreread command. Use standard file compression tools to
reduce the size of a report log file when it is no longer being written.
To avoid corruption and for performance, it is suggested that the vendor daemon write its report
log to a file on a disk local to the system running the vendor daemon. Each vendor daemon must
write to its own report log file.
