Package: zoneminder Version: 1.30.0+dfsg-2 Per /usr/share/perl5/ZoneMinder/ConfigData.pm, ZoneMinder has a configuration variable ZM_TELEMETRY_DATA that can be set to "yes" (the default) or "no" to respectively enable or disable automatic transmission of usage information to the ZoneMinder upstream.
I don't care for opt-out "telemetry" of this sort, so I added ZM_TELEMETRY_DATA=no to the /etc/zm/zm.conf file prior to starting ZoneMinder for the first time. Unfortunately, when I started ZM, the log file showed these entries: 2017-03-24 23:26:56.638730 zmtelemetry[1722].INF-zmtelemetry.pl [Sending data to ZoneMinder Telemetry server.] 2017-03-24 23:26:56.880710 zmtelemetry[1722].INF-zmtelemetry.pl [Telemetry data uploaded successfully.] Frustrating, to say the least. I have already added ZM_CSS_DEFAULT=flat to this file successfully, so the syntax and variable name should be correct.
