RailsConf 2019 - Troubleshoot Your RoR Microservices with Distributed Tracing by Yoshinori Kawasaki
In microservices architecture, it is often challenging to understand interaction and dependencies between individual components involved in an end-user request. Distributed tracing is a technique to improve observability of such microservices behaviors and to help understand performance bottlenecks, to investigate cascaded failures, or in general, to troubleshoot.
In this talk, I will show how we’ve implemented distributed tracing in Rails apps using OpenCensus, a set of vendor-neutral libraries to collect and export metrics and traces, and real world examples from our system that consists of about 100 microservices built with Ruby, Go, Python, Node and Rust. I will also discuss other methodologies to improve “observability” of Rails apps in microservices and future direction.
If you feel pain in troubleshooting microservices of Rails, you’ll love distributed tracing.
Sexual joining my station. I'm really excited to talk to you at this is my first time it's kind of a troubleshoot you are being raised Microsoft Office is distributed tracing. My name is Justin. These are my two thirty days and did Yuri Japanese. I'm working on that and you can reach me out on any of those accounts. If you have any questions, feel free to ask any question after the dog. I work at the company name the water 3 from Tokyo to provide web services are mobile apps that help people meet and exciting companies with future
teammates with each other and FoodShare there. No, really. Stop Waze Apple, please raise your hands if you work on the Microsoft stock picture. 30% biggest okay. Thank you. And you are suffering from the Vikings or fixing dinner whenever a problem for you. And how many are you working on the Monterey? CA creators of freezer hand is thank you. You are a key must be productive and guess it's like a gigantic 10 years old when you are enduring Jim crows, really really
creepy. So this took it for you. And I was doing this before we vote on the board. I made it this morning and I'm on at UB DC Channel. This talk, I will explain why you need to distributed tracing what it is and how it helps in microservices architecture. And in the second. I will introduce open sensors, which is a set of rivalries for distributed tracing and other over the ability features and I will show you how you can use opencensus in Ouray is applications. If it's before
I go into distributed tracing unfrosted about Microsoft's. Yeah, everyone talks of the Microsoft. This is just right and it was great and later. You start doing microservices. You realize it too difficult to do things right in microservices. Let me show you something to hear from our system. This is a system used to look like when it's growing back in 2012. I was separated right maricic and raised up with one tiny database. After 7 years and we have offices in foreign countries provide more than
22 princess. We use five different language so I can do we go buy the material things people want set Northern Trust for whatever reasons. You can tell how complicated it is now. No challenge with Microsoft secure is understanding them into your system. Depressive Curry which microservices are involved in an end-user interaction. And you need that information. You need to know it when program happens. This is an example. I'm sorry. I picked it up. Oops, sorry.
So this is absurd and when you scan this app detects penis girls and send the image of the current to the back and categorized into your first name last name email address if it is real. I'll get the information about the company and send it back to the user. It doesn't. On the right hand side. You see a secret shirt that you're Straits what exactly microservices and database is involved and from which micro services are called. This truck is made by hand while reading through
this particular one is what's so important for you Engineers invisible to understand how this particular Point works. But you can't do this. You can't do this forever. If your infant you have you just can't make it right. It's not at all. This is not an effective way of using your thank you something. We need this type of information when you use a c fan program at explaining why for instance your herb 7 microservices a b c d e f and g x and y 4X and up micanopy
No, just say in your motor into You observe sabzi is a new dirty raising. Your daughter has something going wrong and you were made in Saturday, but you turned out there was no code change in last one week so we have no clue. You're in trouble now. Stats, you don't have a clear picture of a dependency over those are microservices. What you would have to do this year old randomly speculating and guessing which microservices could affect services in order to find out root cause of the problem.
and even if you have an artichoke dependencies It's too difficult to tell its implication to users because it's going to be cold from feature X or Y. The when something goes wrong you want to know exact use that impressed you need to understand which features are affected. Maybe if your ex is not that important while feature why is much much more difficult to use this because there isn't any issue with why is your why you want to fix it as soon as possible? So these programs
what's distributed tracing address is insults? This represents racing is a technique that captures those are rings of operation involved in a single request. This is a simplified view of a trace. You can tell what are the component components involved? full request service acsdg database and you can tell what and how long is ovulation takes and with your price range for a dingo taking longer time than usual if any Just to explain stamp time in elegy distributed tracing. Chris is a question of operations performed within a single end-to-end request.
a trace can contain March response represents the single operation within address the bhdp could be sick or something. And it can be nested to make a Three Oaks pants with your present relationship of cousin's out to eat or have the parents and I guess it'll do it. Explain can be created by example function within the process for remote procedure call over HTTP request for grpc. For example. And spine contains information such as start time in time, or I don't see
no other context travel information station. Let me show you care. How how old is tributed racing looks like. This one is from. Org which we are each karate president was involved in the stress. It show you where it's been most what time? right, and if you scroll down scroll down scroll down Chris Brown So you can pick us phone, but you will see more information contact information. Like I said, you can set the formation which host an IP used for a stick or credit stuff
on God's plan. I think we'll make sure it's all right. It's a cheap method parameters. You can start responsible song song you can put it here. Got the dog. Rowe Price Optical service map which is effectively a dependency graph of microservices and database. So it's higher. But what about this is dr. Gautam adhikari creates just from right racing later. So this is generated from here to Dayton. You pick any of those UC dependency? And if you inspect you see what are the extreme dependency is? Alright at what's a downstream dependencies are like
I was so... More detailed information on a particular application for service in the point of view that drive. This is from stuck driver of Google Cloud prediction. Braces by for the sample latency data sheet with which other agency or Bureau. What does Nvidia control sample? I need to be your ride distribution. Over the dresser thing so you can create it and I want to try to see with more detail. and like in. The dog song you tell if young dick into more contacts during formation of Ages band if you click on that.
Okay, so let's talk about open Santa's now. Opencensus is a set of vendor in neutral rivalries to correct an export president Matrix, but it has more than distributed tracing. It gives more possibility of your entire system. Open sensor is the region area started on Google people from Google Play Stones are in Chiang Rai, very coarse and pencils. But it is now the broke by Broward Community Health Services evaporates and Cloud vendors. Open census provide rivalries for major programming language are most implementations
set the incremental features of a spec E30 be around traffic. I'll be behind stove doesn't provide I never suspected and why you why you like one. I showed you before and you focus it on capturing those danger as it is a difficult birth weight. And when it bends a neutral it means you can send Tracy's or metrics to a bucket of your choice.

You can even sport you might go back in at 1 this is very handy because you can play around with it when you want to try a new burger and cream can use different to see if you want to provide it. It's provides out of box integration for race which are different later in Maine. in opencensus data model is defined using protocol before it so you can take a look at profile on that. They have to understand exact definition. What are the filter? That's all? And style for example
