Logging

Jitar logs all activity, errors and more. To control the amount of logging, you can set the level of interest. The log level is provided as a server option by using the flag --log-level during startup.

bash

jitar start --service=services/standalone.json --log-level=debug

This flag is optional. When not set, the default log level info is used. Other options are debug, warn, error or fatal. All levels will be explained next.

NOTE

It’s not possible to provide an output location, so all the messages are printed pretty in the console. Rerouting the log to a file from the console results in a hard to read log file.

Debug

The debug level is the most verbose level. It will output all messages. The debug level contains messages of running background processes. These are:

Health requested
Health status requested

It's advisable to not use the debug level in production because the health of a worker gets requested frequently. If you experience any issues with this, you can use this mode.

Info

The info level will output all messages, except debug ones. The info level contains messages for all normal actions. These are:

Assets provided
Worker registration
RPC registration / execution
Server start / stop

You can use this level in production, but it is still quite verbose. If you don't need this information then the next level might be a better choice.

Warn

The warn level will output all warn, error and fatal messages. The warn level contains messages for all unexpected results that are not errors. These are:

Asset that could not be found

We advise to use this or the info level in production.

Error

The error level will output all error and fatal messages. The error level contains messages for server and application errors. These are:

Health check that failed
Worker that could not get added
Procedure that threw an error

Fatal

The fatal level is the most severe level. This level contains messages of all actions that are not recoverable. These are:

Server could not start
CLI command that could not be executed
