Setting Startup Options
When the VST daemon vtrd starts, it reads the configuration file
/usr/vtr/config/vtrd.conf. The daemon vtrd is the VST server daemon that
manages the VST parent server processes.
The default installation operates normally without any change to the startup options.
However, you can change the startup options for vvtr, the VST server process by editing
the /usr/vtr/config/vtrd.conf file and adding them immediately after the
program path, /usr/vtr/bin/vvtr. See the vvtr(1) man page for a description of the
startup options.
Checking VST Status
You can use vtrstat to check whether VST is running on the system. If VST is not
running, vtrstat displays the following message:
# vtrstat
Video server on <host> is stopped
If VST is running and responding to MVCP connections, vtrstat displays the
following:
Video server on <host> is running.
For additional VST status information displayed by vtrstat, see “Monitoring the
System” on page 63.
Logging Events
The VST logging feature provides a mechanism for storing a text record of events that
occur during operation of the system. The default logging configuration generally
records only events that are generated by various error conditions, but you can enable
additional logging to help track and troubleshoot VST behavior.
