libhomeradar

Hosts and library statistics

libhomeradar provides a simple interface to get statistics from every added source host.

With the homeradar_stats(H, hostid) function you can request some statistic informations from the given host. This function will return a pointer to the LHR_STATS function.

The pointer must be freed by a call to free().

typedef struct {
  unsigned long bytes;  	// KBytes read from this host
  unsigned long messages;	// Extracted messages from this host
  unsigned long validmsgs;      // Messages which are used by libhomeradar
  unsigned long uniqueacs;      // How many unique aircrafts are contacted on this host
  int connected;        	// 1 = currently connected, 0 = not connected, -1 host deleted
  time_t online;		// How many seconds we are connected to this host

  // Lost contacts because of blocking or slow callback functions
  int lostcontacts;

  // Some stats about this handle
  int icao24_db_items;     	// How many icao24 are known
  int aircraft_db_items; 	// How many different aircrafts are known
  int airline_db_items; 	// How many different airlines are known
  int flight_db_items; 		// How many different flights are known
  int airport_db_items;		// How many different airports are known
} LHR_STATS;

Data logging

You can also log all collected messages into one textfile if you want. For this option you should use the libhomeradar_textlogging() function. The first parameter is the standard library handle, the second the switch mode (TRUE = start logging, FALSE = stop logging)
 
The third parameter is the complete path and filename for the logfile. If the fourth parameter is true then libhomeradar will delete an already existing log, if false then the file will be opened in append mode.
