Would this also work with something like Plausible ( https://github.com/plausible/analytics ) which uses ClickHouse to store web analytics data, or is it primarily for log data?

Despite the fact that Telescope is focused on application log data, it could be used for any type of data as long as it's stored in ClickHouse and has some time fields.

At the moment, I have no plans to support arbitrary data visualization in Telescope, as I believe there are better BI-like tools for that scenario.

Very cool! Would be nice to have a library for the frontend components for the log viewer, to be able to reuse them in other projects :)

Nice idea! However, I’m not experienced enough with Vue (and frontend) development to properly design an exportable component. So, at least for now, I don’t think I’ll be able to make it happen myself.

Just curious, as I'm in the market - why should I use this instead of the ELK stack?

Well, if you're happy with ELK, you should definitely use it! As I mentioned earlier, I’m not trying to sell anything or convince people to switch from their current solutions - just offering an alternative perspective on how things can be done.

From my perspective, a ClickHouse-based setup can be cheaper and possibly faster in certain conditions – here’s some comparison made by ClickHouse Inc. - https://clickhouse.com/blog/clickhouse_vs_elasticsearch_the_...

My motto is "Know your data". I’m not a big fan of schemaless setups - I believe in designing a proper database schema rather than just pushing data into a black hole and hoping the system will handle it.

How is it different from Signoz, a complete observability stack (including Logs) built on top of Clickhouse?

Telescope is focused purely on viewing logs for existing data. It doesn’t enforce any specific ingestion setup or schema and doesn’t support traces or session storage.

You can think of it as just one part of a logging platform, where a full platform might consist of multiple components like a UI, ingestion engine, logging agent, and storage. In this setup, Telescope is only the UI.

Awesome stuff! Just published something similar today Just curious, what is the most challenging thing in your opinion when building such log viewer?

That sounds great! Do you have a link? I'd love to check it out.

For me, the most challenging parts are still ahead - live tailing and a plugin system to support different storage backends beyond just ClickHouse. Those will be interesting problems to solve! What was the biggest challenge for you?

This looks pretty cool, I love seeing more clickhouse-native logging platforms springing up! It's a surprisingly underrated platform to build on when I talk to other engineers.

I'm one of those authors of an existing log viewer (hyperdx) and was curious if we were one of those platforms that didn't fit your needs? Always love learning what use cases inspire different approaches.

There are these guys which are based on OTEL: https://github.com/hyperdxio/hyperdx

+1 for hyperdx, I'm testing it and love it.

author here, just wanted to chime in that I really appreciate the kind words about what we've been building :)

It would be great if the logs could describe a bit what exactly one has to do to use this as an alternative to Grafana Loki. How do I get my logs (e.g. local text files from disk like nginx logs, or files that need transformation like systemd journal logs) into ClickHouse in a way that's useful for Telescope? What kind of indices do I have to configure so that queries are fast? Ideally with some examples. How can I m…

As someone who has never worked anywhere that tried it out, what do you not like about loki. I've been stuck in the very expensive splunk and opensearch/kibana mines for many years and I find it an amazingly frustrating place to be. I honestly find that I can better debug via logs using grep than either of those tools.
