__NOTOC__ | |||
FlightGear has the ability to produce multiple files '''logging properties'''. Both the properties and the interval between the records are user selectable. | |||
More than one log file can be configured in the [[PropertyList XML files|PropertyList file]] setting up what properties to log. | |||
== Simple example == | |||
Here is a simple example that logs the rudder and aileron positions to the file <code>steering.csv</code> every second or so: | |||
<syntaxhighlight lang="xml"> | <syntaxhighlight lang="xml"> | ||
<?xml version="1.0" encoding="UTF-8"?> | |||
<PropertyList> | |||
<logging> | <logging> | ||
<log> | <log> | ||
<filename>steering.csv</filename> | <filename>steering.csv</filename> | ||
<enabled>true</enabled> | |||
<interval-ms>1000</interval-ms> | <interval-ms>1000</interval-ms> | ||
<delimiter>,</delimiter> | |||
