I'd love to just "switch to X", but there is no X which provides all of the above in one great package: Static file serving, load-balanced proxying (TCP/HTTP), fine-grained caching, automatic Let's Encrypt update, API-based configuration (for dynamic upstreams etc), monitoring. Maybe there shouldn't be such a tool. For all other use-cases I go with nginx since it at least provides decent proxying, caching and static…

Correct me if I’m wrong, but doesn’t Caddy 2 do almost all if that?

You mean the software which wouldn't start when let's encrypts acme server was offline and which developers said this is working as intended?

I mean, I'd definitely encourage people to use it for hobby projects, but if that's how the developers see their software, I would never trust them with anything serious.

Had to check, Caching is still missing from Caddy 2, everything else seems to be there [1]. Now if there's no missing minor feature that I rely on in nginx, I might be able to switch eventually, fingers crossed.

This is the tool I've wanted (and half written 3-4 times) my whole career. From reading the github it looks lightweight, not a big infrastructure addition, and that it helps you figure out wtf is going on with the web server. Regarding the branding, for me top is a real-time tool rather than a logging tool. I was picturing something that may have been more useful for older style Apache httpd installs where you have s…

Agreed. The defining feature of `top` is that it updates in real time.

Someone's a little out of the loop.

I know it was "fixed" after thousands of people chimed in.

Nonetheless, I still wouldn't be able to trust developers who think that's reasonable.

if it had been an error and unintentional i wouldn't have been worried. mistakes happen to everyone. but it was an actual design decision. Without serious code review i'd be too worried the developers had any other bright ideas.

My last company had something like that and included response time percentiles (50th, 90th, 95th, 99th) and we had these values graphed and displayed on a big screen in our office. Along with a ton of other performance stats: queries per second, various measures of system load, etc.

Averages can lie, especially when something like an empty query can take close to zero time compared to a non-trivial transaction. If some robot or other artifact of your site is generating a some amount of null queries that will make your average response time look better than it actually is. Percentiles, particularly on the tail of 90th or above, tell a better story of how well and consistently you're responding to traffic under load.

Monitoring capabilities are missing from Nginx on purpose. They are not and will never be available for free because there is "NGINX Plus". This is why I recommend switching to HAProxy.

Nginx does automatic let's encrypt? Since when?

Pro tip: you can make any command into a real-time one with `watch`:

  watch bash -c "topngx
Will run `topngx` against access.log every two seconds and display the output.
