octue streams your logs to
stderr in a nice, readable format so your log messages are immediately
visible when you start developing without any extra configuration. If you prefer to use your own handlers or formatters,
USE_OCTUE_LOG_HANDLER=0 in the environment running your app.
Some advantages of the Octue log handler are:
Its readable format
Its clear separation of log context from log message.
Below, the context is on the left and includes:
Module producing the log
Octue analysis ID
This is followed by the actual log message on the right:
[2021-07-10 20:03:12,713 | INFO | octue.runner | analysis-102ee7d5-4b94-4f8a-9dcd-36dbd00662ec] Hello! The child services template app is running!
Another advantage to using the Octue log handler is that each Octue service is coloured according to its position in the tree, making it much easier to read log messages from multiple levels of children.
In this example:
The log context is in blue
Anything running in the root parent service’s app is labeled with the analysis ID in green
Anything running in the immediate child services (
wind_speed) are labelled with the analysis ID in yellow
Any children further down the tree (i.e. children of the child services and so on) will have their own labels in other colours consistent to their level
Add extra information
You can add certain log record attributes to the logging context by also providing the following environment variables:
INCLUDE_LINE_NUMBER_IN_LOGS=1- include the line number
INCLUDE_PROCESS_NAME_IN_LOGS=1- include the process name
INCLUDE_THREAD_NAME_IN_LOGS=1- include the thread name
