Liz Fong-Jones (方禮真)First talk: WYSIWYG for AWS infrastructure by @antonbabenko. #devopsdaysNYC
Today in the #devopsdaysNYC open spaces, someone was commenting that they were assigning a request ID at Fastly and then propagating it to ELB, their application logs, and more. And having it as a universally searchable key.
That's a good start to tracing, combined w/ timestamps https://t.co/70...
Final speaker of the day is Peter Chestna but I'm pretty fried because of the Google exit process so going to head home early. Hope to see y'all around the community, and hope folks enjoyed the livetweets and my talk! #devopsdaysNYC
Seriously... please please please hold handheld mics like popsicles, not like ice cream cones. It's an accessibility issue. (as well as in this room an issue for the 70% of people on the opposite side of the loooooooooonnnnnnng room) <3 <3 #devopsdaysNYC
[ed: he was brilliant as always and I miss working with him!] #devopsdaysNYC
The things people generally measure today like API uptime, error rates, or database query latency don't tell you anything about whether users can log in, buy things, or search for items. Take a step aside and think from your users' perspective. [fin] #devopsdaysNYC
It absolutely is more work to measure black-box from users' perspectives [ed: or RUM], but you can measure your service the way users experience it. It's worth it. #devopsdaysNYC
Take an example shopping website service: if we just check whether we can login, that doesn't validate whether people can add items to the cart. You need to look at the *entire* user journey. #devopsdaysNYC
There are a lot of things to care about, how can we measure only a few things to get everything? If you start from the most complex thing (correctness), you automatically get availability etc.
You still have to measure responsiveness separately. #devopsdaysNYC
How does this actually look? We don't just want to verify the service is running, we have to make sure that it's available to users and performant enough. and returning correct results. #devopsdaysNYC
