## Debug output
|
||||||
|
|
||||||
|
You can add `--debug[=N]` to the command line to log debug output.
|
||||||
|
This will be logged to the file `hledger-ui.log` in the current directory.
|
||||||
|
N ranges from 1 (least output, the default) to 9 (maximum output).

## Debug output
|
||||||
|
|
||||||
|
You can add `--debug[=N]` to the command line to log debug output.
|
||||||
|
N ranges from 1 (least output, the default) to 9 (maximum output).
|
||||||
|
Typically you would start with 1 and increase until you are seeing enough.
|
||||||
|
Debug output goes to stderr, interleaved with the requests logged on stdout.
|
||||||
|
To capture debug output in a log file instead, you can usually redirect stderr, eg:\
|
||||||
|
`hledger-web --debug=3 2>hledger-web.log`.
