Yuuichi Akagawa / Mbed 2 deprecated FluentLogger_Hello

Sample for the FluentLogger library.

Dependencies:   EthernetInterface FluentLogger mbed-rtos mbed

Fluentd Logo

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>
