Caddy2 logs parser

[azertylr]

Hello,

Does someone have a Caddy2 log parser please?

Thanks!
Best,

Hi @azertylr,
I'm not knowledgeable of Caddy logs format but looking at the docs, it seems that it should be able to output a JSON format which is then trivial to digest by Logdy. In any case, whenever I found a cumbersome format, I ask ChatGPT for help with quickly coming up with an appropriate TS code. Does that help or are you looking for something more specific?

Hi Peter,

Yes it should be possible to write the parser. I was just looking to save time :) I'll try to do it and share it with the community.

Here is a configuration for Caddy2, if someone is interested!

Perfect! Thank you for contributing! ❤️

Maybe you could add an example folder to store config or in the help?

How can I convert a row from unix time stamp to string please?

line.json_content['ts'] = 1726299932 and I want to convert it to DD-MM HH:mm:ss.SSS

Thanks!

[PeterOsinski]

Hey, you can use moment anywhere in the transformation code link.

line.json_content['ts'] = moment(1726299932).format('DD-MM HH:mm:ss.SSS')

Please be advised that your timestamp is in seconds resolution, hence you will not see any SSS milliseconds.

Thanks! I've updated the config
