hello aspecto . I need some help on setting up optelemetry could you pls help me on that . I am new to this facing some issues

Q. What if I'm trying to integrate a nginx serverlog from another server. How would it go?

Thanks a lot @Aspecto.

it was pretty convoluted way to go over "fundamentals". 1 star

you say "uhh uhh uhhhh" every few seconds

Thanks for Great session. I have few questions. What is the benefit of using opentelemetry over normal spring boot default metrics? We have a batch auto scaling application and We are doing analysis if We can use otel

the best explanation sofar. thank you

This man is goated

עוזר ממש כל הכבוד

This is really helpful

is that possible to sample both the parent base and trace ratio base on the SDK side?

I have downloaded the code yesterday. I have started the items and users services on my local. I have also run docker compose, so all the apps are running, no problem. I see the items and users app are started with the 8081 and 8091 for prometheus to scrape metrics from. My question is, I don't see any app started on 8081 or 8092. Also, I see on the video when you trigger localhost:8081/metrics you can see metrics displayed, on my local it shows no connection found. Did you start explicitly any app listening on 8081 and 8092 ?

Where is the code repository for this example?

opentelemetry is so overcomplicated.

Really great walkthrough. Can you post the link to the Github for the source code?

Very informative, thank you!

can you please make a video on collecting infra level metrics & logs from kubernetes cluster using opentelemetry using deamonset mode (without doing instrumentation to application/microservices). And View those metrics & logs in grafana and store those metrics & logs in Storage Accounts &/ Database. Is it possible?

Hi thank you for your video. Do you have github code for the example you used in the video at 35:41? Thanks a lot!

Thank you for the video, really helpful! One question I had was why doesn't Jaeger show different colors for different services : for example different colors for "otel-troubleshooting" and "redis" services?

what is the difference between OTEL collector and statsD ?

Learning lot from this bootcamp, Thanks

Great series!

Thanks, great video! Any chances to get access to the demo code?

i am getting this app errors while running the docker-compose .

Can we integrate Open Telemetry with scala application, if yes, can you share the details on the same?

This is was really helpful. It is hard to find information about redis pub sub tracing.

Can the collector replace filebeat and metricbeat and send log, metric and traces directly to ElasticSearch?

Thanks! That saved me a bunch of time, coming from Datadog/Sentry, OTel is a bit heavier on the jargon and has a few more moving parts to get right.

i am using java, and apart from context propagation, all bits (that i need to start with) are automatically instrumented.... how do i configure context propagation for rest requests, rabbit messages, etc?

git repo for the code?

This video was very helpful for me.

I thought that one of the important architectural characteristics of Prometheus is that it collects data from the services that it monitors. By having the Prometheus exporter is it providing a new location to scrape or is it pushing data to Prometheus?

A PPT show? -Very unprofessional for the subject matter.

I have a naive question about that why you need to use a col-agent and a col-gateway? I mean it's ok to use only one otel-collector to receive, process, and then export the span data to jaeger-collecor then store into ES? Meanwhile, another question is that in your scenario, if the jaeger-agent component is unnecessary because your endpoint is "jaeger:14250" which means your directly connect to jaeger-collector?

Hi. can I export open telemetry data diretly to mongodb or some another data base and configure jaeger to get data from it. Do we have any direct exporters we can use to export data from OpenTelemetry collector to DB?

Good Lesson. Please next time, make sure to put your code as a reference for us to play and try. It saves a hell lot of time. Thanks

can i get the github link of those projects above?

can i get the github link from that project used in this video?

Thanks for the explanation! However export to any vendor is not working ? Does it have dependency on docker , i don't have docker setup in my PC

I liked the bootcamp and really benefited from it. I would like to add a note at 26:53 , OTLP expoter now supports telemetry signal "logs" , we would need to use otel-collector >0.61.0

Thanks for the information 🙂

Thanks for the information. This is really helpful. I have one query. I came across one issue in OTEL collector pod for DataDog Exporter. I am not able to set a proxy for DataDog exporter as the Data Dog site is only accessible through proxy. Do you have any idea. Your help will be highly appreciated. Thanks.

Thanks very helpful!

How can I sample traces based on url ? Thanks in advance

@aspecto_io Is this a better lecture to follow regarding the collector with respect to the one given on your bootcamp?

Thank you Michael

Amazing!! 🚀

Love the presentation on open telemetry, thanks for sharing. I have a question regarding the following scenario. Is there a possibility to connect the trace is and span id with information coming from other sources. For example I run function x with input this and output that for which I have a span generated that I will add in the logs with structured logging and would like to cross reference it with metrics that were collected by kubernetes, or other sources to be able to identify which function generated an unusual spike in my memory graph. I would like to be able to navigate between graphs and see different aspects of the same problem for root cause analysis. A second question would be, if I use hibernate and use a span for it, can I somehow connect the transaction on the hibernate side in Java, through a unique id to a database transaction, so that in case I have issues with the call to be able to investigate (database in the beginning, networking maybe afterwards). Last question as to do with the response to an http(s) request. I would like to be able to capture the end time, packet received and success or failure as part of this in an application as part of the end to end flow. Can it call back somewhere to the gateway as the end step of the flow to finalize the validation of the package arrival?
