How Adobe uses OpenTelemetry Collector (2023)

by AdobeChrisa Featherstone'aIShubhanshu Suranapraised the OpenTelemetry collector as the Swiss army knife of visibility in his speech onNorth America's Open Source Summit.

They went on to explain how they use it to track the massive amounts of viewability data their company collects, including metrics of 330 million unique rows per day. data range of 3.6 terabytes per day. and more than 1 petabyte of log data per day.

Adobeov Chris Featherstone and Shubhanshu Surana

Featherstone, senior director of software development, explained that not all of this data goes through his team or the Otel collector, but "it's a pretty good part of it."

Distributed tracking led his team toOpen telemetry. He explained that Adobe is mostly made up of acquisitions, and with each new company, people have their own opinions about the best cloud, this tool, this word processor, and so on.

"Especially with distributed sensors, this becomes a major challenge," he said. “Imagine trying to hurt an open source cloud provider. This finally led us to the collector. But we tried to build a distributed discovery platform based on Jaeger agents." It was in 2019.

Otel Collector was released in April 2020 to replace the Jaeger Agents. At the beginning, the collector was only supposed to absorb traces, but in September 2021 he brought measurements and logs are also trying to bring.

How Adobe uses OpenTelemetry Collector (2)

The team manages applications using open telemetry libraries, mostly automated instruments and mostly Java. Something enriches the app, it fetches Adobe-specific data, and enriches its pipelines as data flows into the collector. It has some custom extensions and editors, the team makes customizations with GitOps where possible.

“The aggregator is very dynamic and expands to multiple destinations with a single dataset, which has been huge for us. …We sometimes transfer data about collectors to other collectors for further processing. So it's the Swiss army knife of visibility," said Featherstone.

ForJavaservices specifically have a base container and "if you are using a java image you should use it... It already has a lot of quality of life features built in including the Java OpenTelemetry facility in the container [The configuration is] taken from our documentation and is exactly how we configure it for Java.

“So we set the Jaeger endpoint to a local DaemonSet collector. We set the metrics exporter to Prometheus, set the multipliers, set additional resource attributes, set tracer, exporter to Jaeger. And we set the tracking picker to always off depending on the parent," he said, noting that all of this is built into the Java image.

So with these configurations, any running javaAs Kubernetesat Adobe is already involved in discovery. Everything configured this way goes through the collector.

"So everyone participates in the discovery by just turning around," he said. “Measurements, we tried to reduce friction, people will still have to extract these metrics from this exporter somehow. We've made it easy enough, but it's not automatic." He said about 75% of what they run is Java, but they are testing the same ideaNode.jsIPythonand other photos.

Data management

"They're doing a lot of enrichment, and they're also making sure they're not being sent covertly as part of our data or discovery metrics," said Surana, a research engineer at the company.

It uses multiple processes, including a reduce processor, as well as a custom processor in OpenTelemetry Collector that allows them to eliminate some fields they don't want to transmit in the background, which may be personal or other sensitive data. They are also used to enrich the data, as adding more fields such as service IDs, Kubernetes clusters, and regions helps narrow down the search.

“Adobe relies on active acquisitions and we launch many different products in different ecosystems. There's a high probability of conflicting service names across products or with similar microservice names, so we wanted to make sure that didn't happen," he said.

It also uses Adobe's service registry, where each service has a unique ID associated with the service name. Allows each Adobe engineer to uniquely identify the service in a unified discovery background.

"It also allows engineers to quickly look up things, even if they don't know the service or who owns it, they can look at our service record, find the engineer contact for that product or team, and call to resolve the issue," Surana said.

They also send data to multiple export destinations.

"This is probably the most common use case," he said. “Before OpenTelemetry Collector, Adobe engineering teams used different processes, different libraries in different formats. They sent it to vendor products, open source projects, and it was very difficult for us to get the engineering teams to change their backend or just make minor changes to the backend code or application code because the engineers have their own products and product requirements that they are working on.

“With the introduction of OpenTelemetry Collector, as well as the OTLP [OpenTelemetry Protocol] format, it has made our job a lot easier. we are able to send their data to many vendors, many tools with just a few changes on our side.”

Last year, they were able to send indexing data to three different backends simultaneously to test one specific engineering use case.

They now send the data to another set of Otel collectors at the boundary, where they can perform transformations such as inverse sampling, rule-based sampling, and performance-based sampling.

He said they are always looking for other ways to get richer information while sending less data in the background.

"All this configuration is controlled by git. We use OpenTelemetry OperatorHelm diagrams primarily for our infrastructure use case. ... It removes the responsibility of engineers from being experts in a given field ... and makes setup very easy," he said.

Instrumentation automation with OpenTelemetry Operator allows engineers to pass just a few notes to automatically arrange their services for all different signals without writing a single line of code.

"This is huge for us," he said. It takes developer productivity to the next level."

How Adobe uses OpenTelemetry Collector (4)

They also created a custom extension on OpenTelemetry Collector using a custom authentication interface. They had two main requirements for this authentication system: the ability to use one system to securely send data to different backends, and the ability to protect both open source and vendor tools.

OpenTelemetry Collector includes a rich set of processes for creating data processes, including an attribute editor that allows you to add attributes to log data and matrix data. It allows you to transform, enrich or modify the transmitted data without the need for any action by application engineers. Adobe also uses it to improve the searchability of its wallpapers.

The memory throttling processor ensures that Otel never runs out of memory and controls the amount of space needed to maintain state. They also use the Range to Matrix Editor and the Service Graph Editor to generate trace data and create metric dashboards on the fly.

What's next?

According to Featherstone, two things: improving data quality, which means getting rid of data that no one will see, and limiting speed limits to the limit.

The collector allows the edge device to create rules and drop some data.

“For the measurements, imagine that we managed to assemble the collector itself. You know, maybe we don't need a 15-second detail, let's cut it down to five minutes and then send it," Featherstone said.

“Someone else might be sending some metrics for long-term storage and some for further processing in some operational data lake or something. We have the ability to rotate the manifold properly and do all sorts of things.”

Another thing is the speed limiter holes on the edge.

“We have one of our endpoints that gets around 60 billion visits a day and we're trying to keep track of that. This becomes a lot of data when you're talking about sending it somewhere for storage. So we are trying to figure out where are the right places to apply the rate limits to which collectors and at what levels…

They also try to focus more on solving problems first.

"We have so many east/west services that we're trying to do it through records and we're trying to get the right index of records for any group, and I have access to that or whatever. It's so slow and so hard to do that we're trying to really change the way people solve problems at Adobe to something like this where we've put a lot of effort into making these paths quite comprehensive," he said.

They also watch how people deal with problems and provide tools that have the best way to do it.

They are looking forward to integrating the OpenTelemetry logging libraries with core application libraries and running Otel collectors as sidebars for sending measurements, traces and records. They explore newconnectorand creating an edge tracking sampling extension to improve data quality.

Finally, he praised the architecture of the collector plugins and the ability to send data to different destinations with a single binary. That said, there is a rich set of extensions and editors that provide a lot of flexibility in data processing.

"Overall, OpenTelemetry feels very similar to the early days of Kubernetes, when everyone was buzzing a bit about it, and it started out like we were in a hockey rink right now," he said. “The community is great. The work is amazing. If you haven't messed with a collector yet, you should definitely check it out."
