For the backend metrics we use load time data from our Apache logs. For the front-end we have a private WebPagetest instance, and aggregate the data from those tests. Happy to provide more detail if you are curious!

Hi Jonathan,
Interesting article! Which tools do you use to measure page load speed?
Cheers

As Mxx says, that “double the RAM” rule is severely broken nowadays. If you have an app gone wrong and it starts to chew up swap, your server is going to be basically unusable until it’s all used up, and on spinning disks at 192GB or bigger, that’s quite some time. You may as well just reboot the box at that point.
We basically allocate 2GB on every server, regardless of amount of RAM, since having none is still inadvisable (at some point there were flawed formula in the kernel that meant you could never allocate all your physical RAM if swap == 0, not sure if they still exist…) although we aim to never use a single byte of it.

kc, if your server has 64GB of ram and you “double-the-memory-size” that means your apps would need to try to consume 192GB of RAM to utilize all of swap and all of ram. If you are ever in that situation, you have severly misconfigured servers.

Back in sub-2GB days that was somewhat more realistic scenario, but I think on servers with 16GB+ it’s unnecessary.
My(not etsy) 2cents.

Do you allocate swap space, and what’s the recommended size? Someone told me that swap is useless on big-mem server nowdays, however, I am not sure whether it is still common practice to allocate double-the-memory-size disk space.

http://github.com/liuggio/statsd-client is 404 … doesn’t exactly inspire confidence!

on PHP and composer there’s https://packagist.org/packages/liuggio/statsd-php-client that is quite good.

@TOMFUERTES

Just a quick comment on your gist snippet, you no longer need to use http/https prefix when including remote assets such as javascript.

Simply do //.

Yes you do have to specify. Check out the localConfig.js for an example

Hey Guys

Saw at Scaleconf and decided to get supergrep, I installed node.js and npm and got it running.

Unfortunately there is nothing showing that is being logged, do I have to specify log paths? How/where can I learn/read more about the configuration.

I am not a linux/server expert and just know enough to make my apps work

thanks!
