View of the Status->Licenses menu without crontab running the script.
During the installation of ThinLinc server, there is no check for if crontab is installed. We depend on crontab for updating the license usage graphs in Web Admin, since we use it for running the script tl-collect-licensestats.
Without the cronjob running, we get no graphs. See attachment.
The resulting error of not running the cronjob can be seen in /var/log/tlwebadm.log:
ERROR: opening '/var/opt/thinlinc/statistics/users-licenses.rrd': No such file or directory
The missing file users-licenses.rrd gets created by tl-collect-licensestats when it runs.
