Congrats on the launch!

Do also check out SigNoz [1] We are working on a similar problem statement ;)

Awesome! Would check out the github issue

Not sure if OP is from Dylibso, but would love to see telemetry data emitted in OpenTelemetry format as well so different tools (including open source ones) which support Otel format can also consume this data.

I am one of the maintainers at SigNoz [1], an otel native open source observability platform and would love to enable our users to see telemetry data from WASM

Congrats on the launch! Curious to learn what specific use case you have seen around observability of LLM apps which are not covered by standard observability tools like DataDog, SigNoz, etc

Also, how do you compare in terms of features with DataDog's LLM monitoring product which was launched recently?

Disclaimer : I am a maintainer at SigNoz

Thanks for the detailed feedback, this is gold!

> - where do I go see the metrics? There's no "Metrics" tab the way there's a "Logs" and "Traces" tab. A "Metrics Explorer" would be great.

Great, idea. This is some thing which few users have asked for and we will be shipping this in few releases

> - when I have a plot in a dashboard and I see it is trending in the wrong direction, it would be nice to be able to create an alert directly from the chart rather than have to copy the query over.

Fair point, this is something which is also in the pipeline.

> - I'm not sure if there's a way to view only root spans in the trace viewer.

We launched a tab in the new traces explorer for this, does it not serve your use case?

> - when I add a new plot, having to start out with a blank slate is not great. Datadog defaults to a generic system.cpu query just to fill something in, I find this helpful.

We can do something like this, but we don't necessarily know the name of metrics users are sending us, wrt. DataDog which has some default. metrics which their agents generate.

Will also look into other feedbacks you have given

Great to hear that. I am one of the maintainers at SigNoz - if you have any queries as you implement , do ask in our slack - https://signoz.io/slack

If you’re looking for open source APM stack which is OpenTelemetry native and you can self host - you can check out SigNoz ( https://github.com/SigNoz/signoz)

Do check this doc from Otel https://opentelemetry.io/docs/instrumentation/js/getting-sta...

It is not completely solving the issue, but a starting point

Thanks for mentioning SigNoz, I am one of the maintainers at SigNoz and would love your feedback on how we can improve it further.

If anyone wants to check our project, here’s our GitHub repo - https://github.com/SigNoz/signoz

yeah, I would also love to find out about that

Might be interesting to check out SigNoz (https://signoz.io)

Has all the three key signals like Metrics, Traces & logs in a single pane and it is much more cost effective compared to Datadog/NewRelic. And if you want, you can just host it your self as it is open source (https://github.com/signoz/signoz)

(PS: I am one of the maintainers)

the visual query builder looks neat and useful!

you can check out https://github.com/signoz/signoz - for observability & monitoring

Awesome. Reach out to us in our slack community - https://signoz.io/slack if you have any questions

Agree, I think PostHog adresses a very different set of use cases

(SigNoz maintainer here)

I would say the key way we differ from Grafana stack, is that we have all metrics, traces and logs in a single application while in grafana you would have to run 2 different products for this and then work your way to make sure that the three products are able to talk to each other.

One can easily monitor their JS based frontend application in SigNoz today, but yes we are focused primarily on tying together metrics, traces and logs today - and have a pretty powerful exceptions monitoring product built on top of traces.

We don't do things like session recording etc today :)

Do also check out SigNoz - https://github.com/signoz/signoz if you are also interested in APM, metrics

You should check out SigNoz - https://github.com/signoz/signoz

We are not specifically focused on web app monitoring, but you should be able to monitor web app easily, esp. if you want to also monitor backend services and have frontend in JS

And, yeah - we have all the docs for self hosting - https://signoz.io/docs/install/

Docs for Angular apps - https://signoz.io/docs/tutorial/instrumenting-angular-fronte...

In case you are looking for alternatives to DataDog, you can check out SigNoz (https://github.com/signoz/signoz) - we are an open source DataDog alternative and natively support opentelemetry

Curious, do people actually use high cardinality data to make decisions or it is more of the case to store all labels if needed in future

We've been using Struct for SigNoz slack community. Here's how it looks https://knowledgebase.signoz.io/kb

Since, our community is so active, it helps a lot to have a tool like Struct to summarise discussions and have it for future reference.

> Some backend providers still don't support opentelemetry format.

You may want to check out SigNoz (https://github.com/SigNoz/signoz) - we are natively built to consume data sent in OTel format, and it's the only SDK we support

I am not sure when you tried OpenTelemetry, but it is decently mature now, esp. for tracing. I am a maintainer at SigNoz (https://github.com/signoz/signoz) and we have good support for tracing using Otel for most of the common frameworks.

I agree it was a bit rapidly evolving in early days, but now its much more mature.

You can check out our docs for distributed tracing here - https://signoz.io/docs/instrumentation/

Folks on this thread might want to check out SigNoz (https://github.com/SigNoz/signoz). It's an open source alternative to Datadog.

I am one of the maintainers at SigNoz. We have come across many more horror stories around Datadog billing while interacting with our users.

We recently did a deep dive on pricing, and found some interesting insights on how it is priced compared to other products.

Datadog's billing has two key issues:

- Very complex SKU based pricing which makes it impossible to predict how much it would cost

- Custom metrics billing ($0.05 per custom metric) - we found that custom metrics can account for up to 52% of the total billing which just does not make sense

More details in the blog here with a complete spreadsheet for detailed calculation https://signoz.io/blog/pricing-comparison-signoz-vs-datadog-...

You should check out SigNoz (https://github.com/SigNoz/signoz) - It's an open source alternative to DataDog with metrics, traces and logs in a single application. You can just self host it yourself or try the hosted version.

PS: I am one of the maintainers at SigNoz

We are building SigNoz (https://github.com/SigNoz/signoz) - an open source alternative to DataDog. We are natively based on opentelemetry and see lots of our users very interested in that.

As mentioned in some other places in the thread, DataDog pricing is very unpredictable and high - and I think more open standards based solutions are the way forward which provides users more predictability and flexibility

Congrats

Yeah, we are actively working on correlation. We have metrics, traces and logs in a single app - so we should be able to provide a seamless correlation.

Thanks for the point about Notebooks, we have not thought in detail on how people use that. Is it primarily to collaborate between team members when an incident happens or even when there is no incident, and you are analysing stuff
