Hello,
I want to write all log to standard error and standard output with a timestamp prefix: where I have to modify?
Thanks in advance.

Hi,
You can either write our own script, pipe mitmdump’s output through some unix tool that adds timestamps, or modify [https://github.com/mitmproxy/mitmproxy/blob/master/mitmproxy/addons/dumper.py](https://github.com/mitmproxy/mitmproxy/blob/master/mitmproxy/addons/dumper.py). 🙂

Thank you for your response.
I try to modify the class you linked insert the command
**`text = datetime.today().isoformat() + ' ' + text;`**
before the line
`click.secho(text, file=self.outfp, **style)`
in the method `echo`
but with mitmdump I don’t see any difference in the standard output.
What can I do?

I came back to this point and I see this log:

How can I put a timestamp before every line? Can I put also the log level (ERROR, WARN, INFO, …)?
Thanks

Oh, it looks like you also need to adjust [https://github.com/mitmproxy/mitmproxy/blob/master/mitmproxy/addons/termlog.py](https://github.com/mitmproxy/mitmproxy/blob/master/mitmproxy/addons/termlog.py). 🙂

Perfect!
I added
```
#add timestamp and log level as message prefix
ts = datetime.utcnow().isoformat("T", "seconds")
level = "{:5s}".format(e.level.upper())
e.msg = ts + " " + level + " " + e.msg
```
before the click.secho calling (from datetime import datetime).
Here the result:

Thanks for this tip. I modified
- /home/pi/.local/lib/python3.5/site-packages/mitmproxy/addons/termlog.py
on my raspbian linux
How do I regenerate the pyc file?
