    I happen to work with otel a lot so I'll offer a few of my thoughts:

    - Consider decoupling your collector from whatever is consuming your traces with something like kafka. Traces can be pretty heavy and it can be tricky to scale collectors. If something goes down, it's probably a good idea to continue writing the traces to queue or topic.

    - https://www.otelbin.io is a nice little tool to help with collector configuration

      I've been putting off a self-hosted observability setup for a long time. Any recommendations on basis ease of setup and operation? (For something low-medium scale).

      My ideal setup would be to just write SQL on telemetry data and plot dashboards / set alerts.

      Also, thoughts on Vector vs otel agent?

        > For something low-medium scale.

        This isn't a lot to go on.

        The important thing is what you're trying to instrument - hosts, applications, network, microservices, all of the above? (And then whether you want a few weeks retention, or keeping years worth.)

        Grafana in front of Prometheus with node-exporter or telegraf (it can expose in prometheus mode) on the clients -- will tick a lot of boxes and is fast to get going.

        Grafana in front of InfluxDB + telegraf is similar, but personally I find PromQL easier than InfluxQL.

        Read up about the design of TSDBs and log / tracing datastores - their design & intent heavily influences their query languages.

        IMO, with the current tech, it entirely depends on what data you're talking about.

        For metrics and traces, I would use the OTel collector personally. You will have much more flexibility and it's pretty easy to write custom processors in Go. Support for traces is quite mature and metrics isn't far off. We've been running collectors for production scale of metric and trace ingest for the past couple of years, on the order of 1m events/sec (metric datapoints or spans). You mentioned low volume so that's less important, but I just wanted to mention in case others find this comment.

        Logs are a bit different. We looked in to this in the past year. Vector has emerging support for OTLP but it's pretty early. Still, I bet it's pretty straightforward if your backend can ingest via OTLP. Our main concern with running the otel-collector as the log ingest agent was around throughput/performance. Vector is battle-tested, otel is still a bit early in this space. I imagine over time the gap will be closed but I would probably still reach for Vector for this use-case for higher scale. That said, YMMV and as with any technical decision, empirical data and benchmarking on your workloads will be the best way to determine the tradeoffs.

        For your scale you could probably get away with an OTel collector daemonset and maybe a deployment with the Target Allocator (to allocate Prometheus scrapes) and call it a day :)

        HyperDX is really great. It is basically SQL on telemetry data in clickhouse.

        Don’t use vector or otel-agent. Add a materialized view in clickhouse to transform data and swap HyperDX to load from your view (in the UI.)

        I'm using OpenObserve - it does logs, metrics and traces all under one roof. Handles alerts too.

        It's been solid, but the UI is kind of clunky and a little buggy here and there. Dashboards are tricky to setup too. But it has no dependencies, and was easy to setup, and I couldn't find anything else that handled logs too.

        • pranay0110 hours ago
          you might want to take a look at SigNoz - https://github.com/SigNoz/signoz logs, metrics & traces in a single pane and you can create advanced alerts and dashboards as well

          PS: I am one of the maintainers

          • godisdad6 hours ago
            I was able to setup SigNoz on the order of five minutes to view traces in my Dagger builds locally just by exporting the right env vars — it was nice to not have to run and orchestrate three+ tools together
      • sdairs12 hours ago
        Sounds like you should take a look at ClickStack (HyperDX) to me
      • ndhandala13 hours ago
        OneUptime does this with otel. Happy to help! Feel free to reach out at nawazdhandala [at] oneuptime [dot] com

        Seq?
      • cyberax10 hours ago
        I've been using Uptrace in our docker-compose local setup. It runs just fine on a MacBook Air, and has support for tracing, metrics, and logs.

        The UI is predictably an annoying mess, but that's the case with EVERY tracing solution I've tried. Very much including SigNoz.

        • pranay016 hours ago
          SigNoz maintainer here. Curious, when did you try SigNoz (which version/which timeframe) and any specific feedback on what you don't like about it's tracing UI? Would be helpful for us to understand areas to improve on
      • oulipo213 hours ago
        I've been looking at HyperDX (ClickStack) and SigNoz, but those indeed are coupled
        • srcreigh12 hours ago
          I tried both. Signoz is pretty sloppily built. For ex the self hosted option starts a ZK instance with 1 clickhouse host-no way to disable, 800MB ram. Signoz log transformation tool is broken and confusing.

          HyperDX is just a lot better, sure a few papercuts but they got all the important stuff right imo.

          • pranay0110 hours ago
            hey, SigNoz maintainer here.

            Can you share which version of SigNoz did you try or what time frame? We recently made a lot of improvement in how you can host SigNoz including support for Postgres and better docs fro self hosting corretcly - https://signoz.io/docs/collection-agents/get-started/

      This is my architecture, but with NATS. Can confirm, works well.
  • gm67813 hours ago
    I know you can export directly to the backend, but the collector typically uses less than 50MB of RAM in my experience (even when handling lots of traces) and it's pretty easy to add sidecars to however you deploy your backends nowadays. Using Grafana SaaS metrics could look a little spiky or generally weirder without the collector, but normal with it, so I just default to using it now.

    It's the shame the docs on it are still quite bad. The example config in the article here does look almost identical to the one we use everywhere, just without the redact, and should probably be pasted somewhere into the official docs.

    Every provider seems to produce their own soft fork of the collector for branding (eg Alloy, ADOT, etc) and slightly changes the configuration, which doesn't help.

    • theletterf3 hours ago
      The docs are open to contributions! Anybody can add better examples.

    Otel stuff always seems overly complicated to me, but it must just be the types of projects I generally work with. Feels like observability meets java.

    I've dabbled in building a project that collects metrics from the logs for smaller projects. Everyone tells me it's a bad idea, but it seems to work well for me.

      Open Telemetry is the XML of Observability, and is providing the same value XML did when it was first introduced: interoperability.

      Eventually it'll have successors that are better in some way, more efficient, or whatever, but right now there are no alternatives at all. Open Telemetry is the first common standard that multiple vendors have signed up to.

    I did not like working with OpenTelemetry; made me miss the good old days (monolith).
    • CharlieDigital10 hours ago
      OTEL is still useful in a monolith because it allows you to correlate things together, attach nested span, attach events, etc.

    I'm evaluating Greptimedb in prod and while I hate to have a needless component like OTEL-Collector in general, it serves as a read-only gate between the database and the user, so that greptime keeps listening to localhost only, and OTEL-Collector guarantees nobody will write to the database directly.

    If it were to give more fine-grained control over write-only access -- would probably just write directly and let it handle the load.

    • killme20085 hours ago
      Thank you for evaluating GreptimeDB.

      We agree that fine-grained access control is important. A read-only user role will be available in the next major release.

        I had a brief look at greptime db. And I'd like to give a little bit of feedback on your funnel. It is clear that your product marketing is targeting business folks rather than developers. That 3 minute vid on the frontpage was next to useless for me. Also very clearly AI.

        Having stats is nice but i am not choosing your product because of stats. I actually think greptimedb is exactly what I am looking for, I.e. a humio / falcon logscale alternative. But I had to do some digging to actually infer that.

        Your material doesn't highlight what sets you apart from the competition. If you want to target developers which you might not. I dont know.

        I want to debug issues using freetext search, i want to be able to aggregate stats i care about on demand.

    This collector is one of my favorites to ask Copilot Agent to use for validation when the stack is missing tests. You give the agent a couple well written prompts of what you expect to happen and since the app has distributed tracing enabled. all logs flow to text and are consumable by the agent.
  • cyberax9 hours ago
    Just always use a collector. It really simplifies your life. Your app then just always talks with localhost without any authentication. And during the development, you can just set up local Uptrace to help you with debugging with just a different collector config.

    And while all the tracing providers speak the OTEL protocol, the way your do auth is not the same. Sometimes you need to specify it in a header, sometimes it's a part of the URL.
