Most of the server global parameters are set in the XML configuration file. On Linux platforms the path to the file is /opt/traccar/conf/; on Windows the path can be changed during the installation process, but by default it should be in C:\Program Files\Traccar\conf. Configuration file can be edited using any text editor. Please make sure it's a valid XML file and special characters are escaped.
Some of the parameters are configured via attributes on Device, Server and other objects through the web app. Check the badge next to an attribute key for information on where the parameter can be used.
For boolean (true/false) values, if the value is not specified the server treats it as false.
List of available configuration parameters:
Network interface for a the protocol. If not specified, server will bind all interfaces.
Port number for the protocol. Most protocols use TCP on the transport layer. Some protocols use UDP. Some support both TCP and UDP.
List of devices for polling protocols. List should contain unique ids separated by commas. Used only for polling protocols.
Polling interval in seconds. Used only for polling protocols.
Enable SSL support for the protocol. Not all protocols support this.
Connection timeout value in seconds. Because sometimes there is no way to detect lost TCP connection old connections stay in open state. On most systems there is a limit on number of open connection, so this leads to problems with establishing new connections when number of devices is high or devices data connections are unstable.

URL to forward positions. Data is passed through URL parameters. For example, {uniqueId} for device identifier, {latitude} and {longitude} for coordinates.
Additional HTTP header, can be used for authorization.
Position forwarding retrying enable. When enabled, additional attempts are made to deliver positions. If initial delivery fails, because of an unreachable server or an HTTP response different from '2xx', the software waits for 'forward.retry.delay' milliseconds to retry delivery. On subsequent failures, this delay is duplicated. If forwarding is retried for 'forward.retry.count', retrying is canceled and the position is dropped. Positions pending to be delivered are limited to 'forward.retry.limit'. If this limit is reached, positions get discarded.
Position forwarding retry first delay in milliseconds. Can be set to anything greater than 0. Defaults to 100 milliseconds.
Position forwarding retry maximum retries. Can be set to anything greater than 0. Defaults to 10 retries.

Filter invalid (valid field is set to false) positions.
Filter zero coordinates. Zero latitude and longitude are theoretically valid values, but it practice it usually indicates invalid GPS data.
Filter duplicate records (duplicates are detected by time value).
Filter records with fix time in the future. The value is specified in seconds. Records that have fix time more than the specified number of seconds later than current server time would be filtered out.
Filter records with fix time in the past. The value is specified in seconds. Records that have fix time more than the specified number of seconds before current server time would be filtered out.
Filter positions with accuracy less than specified value in meters.
Filter cell and wifi locations that are coming from geolocation provider.
Filter positions with exactly zero speed values.
Filter records by distance. The values is specified in meters. If the new position is less far than this value from the last one it gets filtered out.
Filter records by Maximum Speed value in knots. Can be used to filter jumps to far locations even if Position appears valid or if Position `speed` field reported by the device is also within limits. Calculates speed from the distance to the previous position and the elapsed time. Tip: Shouldn't be too low. Start testing with values at about 25000.
Filter position if time from previous position is less than specified value in seconds.
If false, the server expects all locations to come sequentially (for each device). Filter checks for duplicates, distance, speed, or time period only against the location that was last received by server. If true, the server expects locations to come at random order (since tracking device might go offline). Filter checks for duplicates, distance, speed, or time period against the preceding Position's. Important: setting to true can cause potential performance issues.
Time limit for the filtering in seconds. If the time difference between the last position was received by server and a new position is received by server is more than this limit, the new position will not be filtered out.
Enable attributes skipping. Attribute skipping can be enabled in the config or device attributes. If position contains any attribute mentioned in "filter.skipAttributes" config key, position is not filtered out.
Attribute skipping can be enabled in the config or device attributes. If position contains any attribute mentioned in "filter.skipAttributes" config key, position is not filtered out.
