Prerequisite Please see here to get and set your API Key environment variable.

​
Install the lytix SDK

pip3 install lytix-py

​
(Reccomended) Set you API key via the environment variable

export LX_API_KEY=<your-api-key-here>

​
Set your API key in the code

from optimodel import LytixCreds

LytixCreds.setAPIKey('<your-api-key-here>')

​
Error Class

You can now just replace all your raise Exception calls with raise LError. For example:

from lytix_py import LError, LLogger

async def backgroundProcess():
    logger = LLogger("background-logger", {"userId": '124'})
    logger.info("Some process is starting")
    raise LError("An unexpected error")

async def main(): 
    await backgroundProcess()


if __name__ == "__main__":
    logger  = LLogger("main")
    logger.runInAsyncContext(main)

The error, along with the last 20 log lines will automatically get pushed to the Lytix platform here. See example event here:

​
Error Increment

You can also send an error along with related logs without throwing an error by using the increment method.

from lytix_py.LError import LErrorIncrement, LLogger

async def backgroundProcess():
    logger = LLogger("background-logger", {"userId": '124'})
    logger.info("Some context on the user here")
    try:
        raise Exception("LIncrement error happened")
    except Exception as e:
        logger.error("LIncrement error happened")
        LErrorIncrement("Some error")
                        
async def main(): 
    logger = LLogger("main-logger")
    logger.info("Starting in our main LIncrement process")
    await backgroundProcess()


if __name__ == "__main__":
    logger  = LLogger("main")
    logger.runInAsyncContext(main)
