Looks simple and clean! Big ups for starts of good screenshots, docs, and quickstart (Docker) instructions. Regarding the name, "Telescope" is also the name of a Neovim fuzzy finder[0] that dominates the ecosystem there. Other results appear by searching "telescope github".

Clearly we need an extension to search this new service with telescope.nvim. telescope-telescope.nvim.

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…

Telescope is primarily focused on log visualization, not on log collection or preparing ClickHouse for storage. The system does not currently provide (and I think will not ever) built-in mechanisms for ingesting logs from any sources.

I will consider providing a how-to guide on setting up log storage in ClickHouse, but I’m afraid I won’t be able to cover all possible scenarios. This is a highly specific topic that depends on the infrastructure and needs of each organization.

If you’re looking for a all-in-one solution that can*both collect and visualize logs, you might want to check out https://www.highlight.io or https://signoz.io or other similar projects.

And also, by the way, I’m not trying to create a "Grafana Loki killer" or a "killer" of any other tool. This is just an open source project - I simply want to build a great log viewer without worrying about how to attract users from Grafana Loki or Elastic or any other tool/product.

This one seems to be optimized for log viewing at the moment, are there any DataDog alternatives built on top of Clickhouse, which supports full range of OpenTelemetry features?

Looks cool I might try it out! I need a central place, something simple where I can actually read the contents of the logs that are generated by the dozen of services that I run for clients, etc… instead of stupidly SSH’ing to every server. Does this fit the use case? I tried Loki once but it was painful to set up and more geared toward aggregating events and stats.

If all you want is the plaintext logs, there's no need to bother with special products. Just point syslog in the right direction as if it was 1995. Everything can log to syslog already. Things like Splunk, Graylog and Kibana are mostly for visualization and query interfaces.

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

We've found that ClickHouse is extremely fast for write-once/read-many. So its great for recording logs. If Telescope provides the search/index features that Elastic provides, this could be a nice performance bump. FWIW, I haven't tested Telescope, so this is all just my musing.
