Pinto

Pinto is a lightweight log delegation engine designed for constrained devices. All messages written to STDOUT and STDERR get intercepted, processed, and forwarded to any writeable interface (Serial, Mbed Cloud Client LWM2M M2MBase objects, MQTT, etc.) without having to make any code or test changes. In other words, Pinto enabled devices appear as if they are network-addressable rotating logs located in /var/log.

Features

Examples

Serial Example

This example uses Serial as the DataPlane. This is basically the same behavior found in develop builds

PintoLogger<Serial> pintoLogger(&mbed_cloud_client);
pintoLogger.init_remote_paths(NULL); //Initialize Data Path Serial doesnt need anything special
//pintoLogger.ready(true); //Writers default to ready.

M2MBase example

This example uses Pelion as the Dataplane

PintoLogger<M2MResource> pintoLogger(&mbed_cloud_client);
pintoLogger.init_remote_paths(&mbed_cloud_client); //Initialize Data Path
...
//Set ready when Cloud client registered and connected, otherwise logs go nowhere
pintoLogger.ready(true);

User Custom example

Nothing stops us from writing our own DataPathWriters. All they need is a write(const void* data, size_t len) method!

class DoNothing {
    public:
        size_t write(const void* data, size_t len) { return 0; }
};
...

DoNothing slashDevNull;
PintoLogger<DoNothing> pintoLogger(&mbed_cloud_client);
pintoLogger.init_remote_paths(NULL);
