Sample for the FluentLogger library.
Dependencies: EthernetInterface FluentLogger mbed-rtos mbed
Example for simple message logging.
main.cpp
#include "mbed.h"
#include "rtos.h"
#include "EthernetInterface.h"
#include "FluentLogger.h"
EthernetInterface eth;
FluentLogger logger("192.168.0.1"); // please set your Fluentd server
int main()
{
eth.init(); //Use DHCP
eth.connect();
while(1) {
logger.log("debug.mbed", "Hello mbed"); //message body is simple string
wait_ms(10000);
}
logger.close();
eth.disconnect();
}
Server Configuration
Fluentd daemon must be lauched with the following configuration:
<source> type tcp port 24224 </source> <match debug.**> type stdout </match>
