SURVEY: Who is using Jaeger

[badiib]

Hi, you are in a group of individuals who have create or commented on issues in the Jaeger repository and we are doing a simple informal survey about Jaeger usage. If you could answer the following questions, it would be very valuable to gauge interest in the project:

• If applicable, what company/organization do you represent? How many software engineers?
• How are you using Jaeger? E.g. full production deployment, considering, experimenting, or "I am not using Jaeger" etc.
  • How long have you been using Jaeger?
  • If you are not using Jaeger but chose another tracing system, what were the reasons?
• How many services (or microservices) exist in your system layout?
  • How many of them are traced?
• Can you describe your tracing setup and volumes? I.e. which storage you use, how many traces/spans you store, etc.
• What types of problems are you solving with tracing?

Also consider adding your organization to ADOPTERS.md.

• A financial system service providers company From Shanghai
• experimenting
• To be honest, we are considering zipkin more.My team members are more familiar with ES and MySql than Cassandra, and our java coders like zipkin. Though l as a pure gocoder perfer jaeger.
• We are during a microservice transformation.And our system is half java and half golang.
• BTW, we select a kafka x ES solution with zipkin which jaeger does not provide.

If applicable, what company/organization do you represent?

I am a contributor to fission, which is a FaaS solution on top of Kubernetes.

How are you using Jaeger? E.g. full production deployment, considering, experimenting, or I am not using Jaeger etc.

We need to integrate a distributed tracer for two usage:

• Help to troubleshoot performance problems with fission itself.
• Provide tracer handler to user so that they can instrument their code easily and trace the functions as part of a bigger solution.

Currently I am doing some experiments on the integration.

If you are not using Jaeger, why not?

Will find myself some time to try Jaeger. It seems Jaeger has better client library support.

How many services (or microservices) exist in your system layout?

Around 10 microservices. Excluding user functions, which are also services evolving over time.

• If applicable, what company/organization do you represent?

I work for a subsidiary company of Orange.

• How are you using Jaeger? E.g. full production deployment, considering, experimenting, or I am not using Jaeger etc.

We are experimenting OpenTracing in a futur API Gateway services.

• If you are not using Jaeger, why not?

We use Jaeger using Kubernetes deployment.

• How many services (or microservices) exist in your system layout?

Around 10 services.

• which storage are you using ?

Cassandra.

Interesting to hear folks say jaeger has a better client library, especially as Jaeger is OpenTracing which is supposed to make that point moot between systems. If anyone cares to elaborate on which library (at least language) is being compared and what they like better, that'd be interesting feedback, too.

• Zenly, a live location sharing social network (https://github.com/znly)
• Full production deployment on top of scylladb
• Around 10 services using jaeger in production, more coming

[JodeZer]

@jbdalido glad to see scylladb !

[bharat-p]

• Elastica (part of Symantec)
• Experimenting in QA/Dev systems
• Around 10-15 services/microservices

[hzariv]

• If applicable, what company/organization do you represent?
  --- eBay, Inc

• How are you using Jaeger? E.g. full production deployment, considering, experimenting, or I am not using Jaeger etc.
  --- We are currently evaluating Jaeger and Open Zipkin for OpenTracing

• If you are not using Jaeger, why not?
  --- We have not ruled out Jaeger yet. We used Jaeger Java client first and now evaluating the backend that was recently open sourced. Lack of streaming support for the collector is an issue for Jaeger.

• How many services (or microservices) exist in your system layout?
  --- 500+

Also integration with mesh service proxy such as Envoy or Linkerd is important to us.

If applicable, what company/organization do you represent?
Stitch Fix

How are you using Jaeger? E.g. full production deployment, considering, experimenting, or I am not using Jaeger etc.
Considering/experimenting

If you are not using Jaeger, why not?
The environment for which we are considering Jaeger is mostly Python 3, so waiting either for this pull request to be merged or an alternative implementation :)

[mabn]

If applicable, what company/organization do you represent?
Base CRM

How are you using Jaeger?
Experimenting in production - there's a process which listens on kafka to our custom traces, converts them and publishes to jaeger.

If you are not using Jaeger, why not?
Traces with ~1M spans make jaeger hard to use, have to deal with it first.
As for instrumenting services with opentracing - this will take time, only 1 service has it so far.

How many services (or microservices) exist in your system layout?
100+

Storage
We're using AWS managed Elasticsearch - mainly because it's managed, but also because we have experience with ES and not with Cassandra. I'm still trying to make it work properly though - right now (2017-09-22) it performs poorly and drops a lot of spans because indexing does not use bulk API, indices are created without index.translog.durability=async and AWS ES requires signing of each index so there's additional proxy to go through.

RisingStack

How are you using Jaeger?
Experimenting with automatic instrumentation for Node.js: https://github.com/RisingStack/jaeger-node

If you are not using Jaeger, why not?
Node.js async_hooks is still in experimental phase.
Currently, our own tracing is more feature complete: http://trace.risingstack.com

How many services (or microservices) exist in your system layout?
50+ (our product's backend)

Lightbend has OpenTracing integration for Akka (and this is being extended to more Lightbend technologies, such as Akka HTTP, Play, and Lagom). Many of our customers are interested in tracing for distributed systems or microservices. The Jaeger client is used as the default OpenTracing client to report to Jaeger or Zipkin, giving our customers the option of using Jaeger.

If applicable, what company/organization do you represent?

GrafanaLabs

How are you using Jaeger?

currently prototyping an implementation for our tsdb with the goal of validating performance and suitability and then taking to production.
potentially we may add opentracing to our other software (like Grafana) as well.
our most urgent need was just getting rich, context-specific distributed logging in place so we can diagnose performance trouble and jaeger looks like a good fit. In particular compared to "just distributed logging" systems like ELK/crate or oklog, we realized we want tracing not just logging.

How many services (or microservices) exist in your system layout?

We have about 20 different projects that we run, but many of them run them multiple times (many of our customers have a dedicated single-tenant deployments in kubernetes)

UPDATE sept 22
we're now using jaeger in prod for 2 different projects (each running hundreds times due to multi-tenancy) and we're also working on adding jaeger support into grafana itself.

backend: cassandra
