HyperDX isn't being deprecated, you can probably see on the marketing page it's still really prominently featured as an integral part of the stack - so nothing changing there.

We do of course want to get users onto HyperDX v2 and the overall ClickStack pattern. This doesn't mean HyperDX is going away by any means - just that HyperDX is focused a lot more on the end-user experience, and we get to leverage the flexibility, learnings and performance of a more exposed ClickHouse-powered core which is the intent of ClickStack. On the engineering side, we're working on making sure it's a smooth path for both open source and cloud.

side note: weird I thought I replied to this one already but I've been dealing with spotty wifi today :)

- We're flexible on top of any ClickHouse instance, you can use virtually any schema in ClickHouse and things will still work. Custom schemas are pretty important for either tuned high performance or once you're at a scale like Anthropic. This makes it also incredibly easy to get started (especially if you already have data in ClickHouse). - The above also means you don't need to buy into OTel. I love OTel but some companies choose to use Vector, Cribl, S3, a custom writing script, etc for good reasons. All of that is supported natively due to the various ClickHouse integrations, and naturally means you can use ClickStack/HyperDX in that scenario as well. - We also have some cool tools around wrangling telemetry at scale, from Event Deltas (high cardinality correlation between slow spans and normal spans to root cause issues) to Event Patterns (clustering similar logs or spans together automatically with ML) - all of these help users dive into their data in easier ways than just searching & charting. - We also have session replay capability - to truly unify everything from click to infra metrics.

We're built to work at the 100PB+ scale we run internally here for monitoring ClickHouse Cloud, but flexible enough to pin point specific user issues that get brought up once in a support case in an end-to-end manner.

There's probably a lot more I'm missing. Ultimately from a product philosophy standpoint, we aren't big believers in the "3 pillars" concept, which tends to manifest as 3 silos/tabs for "logs", "metrics", "traces" (this isn't just Signoz - but across the industry). I'm a big believer that we're building tools to unify and centralize signals/clues in one place and giving the right datapoint at the right time to the engineer. During an incident I just think about what's the next clue I can get to root cause an issue, not if I'm in the logging product or the tracing product.

That being said - as you've mentioned so many different "store tons of data" apps have been enabled from ClickHouse. Observability is at a point where it's in the same category of: ClickHouse can store a ton of data, OTel can help you collect/process it, and now we just need that analytics user experience layer to present it to the engineers that need an intuitive way to dive in to it all.

We started building signoz as an OS alternative of Datadog/New Relic four years back and opentelemetry-native from day 1. We have shipped some good features on top of Opentelemetry and because of OTel's semantic conventions & our query builder, you can correlate any telemetry across signals.

What about OTel metrics is difficult?

You can set up receivers for other metrics sources like stasd or even the DD agent, so there's no need to immediately replace your metrics stack.

OTel Metrics: I get it, it's specified as almost a superset of everyone's favorite metric standards with config for push/pull, monotonic vs delta, exponential/"native" histograms, etc. I have my preferences as well which would be a subset of the standard but I get why a unifying standard needed to be flexible.

Statsd: The great thing about the OTel collector is that it allows ingesting a variety of different data formats, so you can take in statsd and output OTel or write directly to ClickHouse: https://github.com/open-telemetry/opentelemetry-collector-co...

We correlate across trace/span id as well as resource attributes. The correlation across logs/traces with span/trace id is a pretty well worn path across our product. Metrics to the rest is natively done via resource attributes and we primarily expose correlation for K8s-based workloads with more to come. We don't do exemplars _yet_ to solve the more generic correlation case for metrics (though I don't think statsd can transmit exemplars)

Elixir: We try to do our best to support wherever our users are, the OTel SDK and ours have continued to change in parallel over time - we'll want to likely re-evaluate if we should start pointing towards the base OTel SDK for Elixir. We've been pretty early on the OTel SDK side across the board so things continue to evolve, for example our Deno OTel integration came out I think over a year before Deno officially launched one with native HyperDX documentation <3

Notebooks: Yes, it should land in an experimental state shortly, stay tuned :) There's a lot of exciting workflows we're looking to unlock with notebooks as well. If you have any thoughts in this direction, please let me know. I'd love to get more user input ahead of the first release.

You see an explosion in offerings, and then eventually it's whittled down to a handful of survivors.

So they switch to Prometheus and Grafana and now have to manage a Prometheus cluster. Far cheaper, but far more annoying.

I've also been in touch with Mike & Ray for a bit, who've told me they've added ClickHouse support recently which makes the story even better :)

Vector supports directly writing into ClickHouse - several companies use this at scale (iirc Anthropic does exactly this, they spoke about this recently at our user conference).

Please give it a try and let us know how it goes! Happy to help :)

We have this on the medium term roadmap to investigate proper support for a compatibilty layer such as ferret or more likely just using ClickHouse itself as the operational data store.

Otherwise yes you can authenticate against the other versions with a email/password (really the email doesn't do anything in the open source distribution, just a user identifier but we keep there to be consistent)

Beyond raw performance and cost effectiveness, which is quite important at scale, we work a lot on making sure the application layer itself is intuitive to use. You can always play around with what ours looks like at play.hyperdx.io :)
