but, but... how?
I feel like I must be missing something here; you want to aggregate your syslog data; you have a bunch of files and a web browser.
Now what?
You beat your keyboard against the monitor while your browser sandbox steadfastly refuses to load your local file system files? [1]
You write your own server that serves data and the open source core? [2]
Yay, you now have the dubious honour of having re-invented jupyter notebooks, only, you had to roll it yourself, and it's insecure and really not very good compared to an existing mature product.
What can you actually do with this, that you can't do by right clicking on your browser window and picking 'inspect', and then clicking on 'console'?
You can certainly make interactive blog posts; absolutely, I 100% acknowledge that as a blog plugin, when you have already got a server to host your content, this would be pretty awesome.
If you do want to run your own databricks / notebook SAS, then I also see it as being a really great kickstart for you, absolutely.
However, out of the box? I'm... like, I think this is interesting, but I don't see how I could actually use it.
