    Hi Harris Support and IDL fans0

    I am running IDL 8.6 with the new flexnetls license server on Linux.
    I want to know how to configure the flexnetls license server to create and
    maintain a log of user activity, i.e., licenses checked in and out, etc.

    This was possible with the old IDL 8.5 and older versions,
    with the flexlmgrd license server.
    The log file is a very useful feature, essential to understand the pattern of activity,
    for accounting purposes, etc.
    The old flexlmgrd license server would even rotate the log files,
    switch to a new file every so often, tag the log files with date stamps, etc.

    Is this feature available with flexnetls (IDL 8.6)?
    How do I configure it to produce the logs?

    Incidentally, the /etc/init.d/flexnetls-idl_lmgrd startup script has some variables
    such as LOGLEVEL and LOG_DIR that suggest this is possible,
    but I couldn't find any documentation on how to use them.
    Likewise, there is a pair of what seems to be configuration files:
    /etc/default/flexnetls
    /etc/default/flexnetls-idl_lmgrd
    but there is no reference to any "*LOG*' variable therein.

    Thank you,
    Gus Correa

    Dear NV5 Geospatial Support and IDL fans.
    I am asking this question again, in an updated context.
    I am running IDL 8.8 with the new flexnetls license server on Linux.
    Question:
    How do I extract statistics of user activity, i.e., licenses checked in and out, etc
    from the server logs?

    This was possible with the old IDL 8.5 and older versions,
    with the flexlmgrd license server.
    The log file is a very useful feature, essential to understand the pattern of activity,
    for accounting purposes, etc.
    The old flexlmgrd license server would even rotate the log files,
    switch to a new file every so often, tag the log files with date stamps, etc.

    There two types of logs in /var/opt/flexnetls/idl_lmgrd/logs/:
    access_YYYY_MM_DD.request.log
    and
    flexnetls.log.YYYY_MM_DD
    However, they don't seem to hold any meaningful information regarding users,
    how many times a user checked a license in and out, from which client computer IP address, etc,
    which makes those logs useless.

    Is this feature available with this new (not-so-new-anymore) flexnetls?
    How do I configure it to produce meaningful logs from where user statistics can be extracted?
    Or was this capablity completely lost when IDL migrated to the new license management software? [That would be terrible!]
    That is a basic requirement for many purposes: accounting, justifying the very purchase of an IDL license, etc.
    Right now I was asked to produce statistics of IDL use, to justify the license renewal, and I just cannot give my higher ups that information,
    because the logs are bare and useless.
    So, not having it is not only bad for me, but also bad for NV5/IDL, as it may lose customers because of this simple, yet fundamental, feature is missing.

    Thank you,

    We have discontinued support for the Flexnet License Server in our products. It is recommended that you install our updated Next-Gen License Server package which has more robust logging. The Next-Gen License Server works out of the box with IDL 8.9+ versions, but also with IDL 8.6 to 8.8 if those installations install the Next-Gen License Compatibility Patch. All of these installers can be found on our download page: https://www.nv5geospatialsoftware.com/Product-Downloads
