  • It's time to let go, Apache Software Foundation

    Trying to play devil's advocate here.

    > It needs at least a stable set of users, but maintaining a set of users is essentially managing the set of people onboarding and the set of people migrating off.

    I could say that I don't care very much about how much users a piece of software has, only that it has enough information on how to use it and enough maintainers to patch any security vulnerabilities and do occasional releases with updated dependencies, as well as address any serious issues or bugs.

    For example, Apache Skywalking is an APM solution that most people haven't even heard of (in contrast to something like Sentry), yet it fits those qualities and I see few to no issues with it:

    > If you're shrinking then a competitor is providing better options, or your problem space has shifted.

    Again, as a user, I might not care that Sentry or another piece of software is better in any number of ways than Apache Skywalking. Similarly, I might not care that something like PostgreSQL is more correct or has a large market share (at least on HN) in comparison to something like MariaDB/MySQL.

    If a piece of software meets the needs of my project and won't effectively rot with time, then it's quite possibly good enough as it is, even if it's not the market leader. For my small project's APM needs Apache Skywalking is enough. For my CRUD database needs, something like MariaDB/MySQL will be okay until the time Sun burns out (or PostgreSQL if I'm feeling fancy, but even that's not one of the modern and hip solutions).

    Ergo, those better options only become relevant once they're closer to being must haves than nice to haves. Same as how Docker Swarm might be enough for many, even if Kubernetes basically won in the "container wars" and has a way more active community. Swarm will only stop being an option for me once it hits EOL, at least for certain projects where simplicity is appreciated.

    Then again, a counterpoint to my own argument here could be the story of LibreOffice and OpenOffice, where the latter was basically donated (instead of the rights to the name being given to the folks behind LibreOffice) and is now in decline while LibreOffice is flourishing - but at the same time they were so close to one another feature wise, that maybe it's not a good point, same as with Gogs and Gitea.

    > Where's Java primarily used these days?

    I've seen a lot of enterprise-y webdev projects use it for back end stuff (Dropwizard, Spring Boot, Vert.X, Quarkus) and in rare cases even front end (like Vaadin or JSF/PrimeFaces). The IDEs are pretty great, especially the ones by JetBrains, the tooling is pretty mature and boring, the performance is really good (memory usage aside) and the language itself is... okay.

    Curiously, I wanted to run my own server for OIDC/OAuth2 authn/authz and to have common features like registration, password resets and social login available to me out of the box, for which I chose Keycloak:

    Surprise surprise, it's running Java under the hood. I wanted to integrate some of my services with their admin API, seems like the Java library is also updated pretty frequently: whereas ones I found for .NET feel like they're stagnating more: (probably not a dealbreaker, though)

    Then, I wanted to run an APM stack with Apache Skywalking (simpler to self-host than Sentry), which also turns out to be a Java app under the hood:

    Also you occasionally see like bank auth libraries or e-signing libraries be offered in Java as well first and foremost, at least in my country (maybe PHP sometimes): and their app for getting certificates from the government issued eID cards also runs off of Java.

    So while Java isn't exactly "hot" tech, it's used all over the place: even in some game engines, like jMonkeyEngine, or in infrastructure code where something like Go might actually be more comfortable to use.

  • OpenTelemetry in 2023
    36 projects | | 28 Aug 2023
    > What should people use?

    I recall Apache Skywalking being pretty good, especially for smaller/medium scale projects:

    The architecture is simple, the performance is adequate, it doesn't make you spend days configuring it and it even supports various different data stores:

    The problems with it are that it isn't super popular (although has agents for most popular stacks), the docs could be slightly better and I recall them also working on a new UI so there is a little bit of churn:

    Still better versus some of the other options when you need something that just works instead of spending a lot of time configuring something (even when that something might be superior in regards to the features):

    Sentry is just the first thing that comes to mind (OpenTelemetry also isn't simpler due to how much it tries to do), but compare its complexity to Skywalking:

    I wish there was more self-hosted software like that out there, enough to address certain concerns in a simple way on day 1 and leave branching out to more complex options like OpenTelemetry once you have a separate team for that and the cash is rolling in.

  • Improving Observability of Go Services

  • Monitoring Microservices with Prometheus and Grafana
    9 projects | | 9 Dec 2022
    Personally I've also used Apache Skywalking for a decent out of the box experience:

    I've also heard good things about Sentry, though if you need to self-host it, then there's a bit of complexity to deal with:

  • How to choose the right API Gateway
    15 projects | | 22 Nov 2022
    Next characteristic of a good API Gateway is effortless integration with more ecosystems. You need to check if it is integrated with other products, tools, platforms, and services. For example, you can investigate if supports several application protocols, and compatibility with third-party identity providers for authentication, and if it provides pre-built connectors that you can easily integrate with Most observability platforms like (Prometheus, Skywalking, ElasticSearch, Opentelemetry, and so on).
  • The Modern Observability Problem
    2 projects | | 20 Nov 2022
    For me, Apache Skywalking feels "good enough", although definitely not perfect:

    The Docker Compose stack for it doesn't look as complicated as that of Sentry, it's basically an almost monolithic piece of software like Zabbix is and it works okay. The UI is reasonably sane to navigate and you have agents that you can connect with most popular languages out there.

    That said, the UI sometimes feels a bit janky, the documentation isn't exactly ideal and the community could definitely be bigger (niche language support). Also, ElasticSearch as the data store feels too resource intensive, I wonder if I could move to MySQL/MariaDB/PostgreSQL for smaller amounts of data.

    Then again, if I could make monitoring and observability someone else's problem, I'd prosper more, so it depends on your circumstances.

  • API monetization using an API Management and a billing provider
    4 projects | | 12 Sep 2022
    For example, Apache APISIX can also integrate with a variety of observability platforms like Prometheus, OpenTelemetry, Apache Skywalking and etc. by using its connector plugins 🔌 to further analyze API performance and gain complete visibility.
  • Go standard library: structured, leveled logging
    11 projects | | 11 Sep 2022
    Technically, you can also use Skywalking for log aggregation, but personally the setup isn't as great and their log view UI is a bit awkward (e.g. it's not easy to preview all logs for a particular service/instance in a file-like view), see the demo:

    For logs in particular, Graylog feels reasonably sane, since it has a similarly "manageable" amount of components, for a configuration example see:

    Contrast that to some of the more popular solutions out there, like Sentry, which gets way more complicated really quickly:

    For most of the people who have to deal with self-hosted setups where you might benefit from something like tracing or log shipping, actually getting the platform up and running will be an uphill battle, especially if not everyone sees the value in setting something like this up, or setting aside enough resources for it. Sometimes people will be more okay with having no idea why a system goes down randomly, rather than administering something like this constantly and learning new approaches, instead of just rotating a bunch of files.

    For others, there are no such worries, because they can open their wallets (without worrying about certain regulations and where their data can be stored, hopefully) and have some cloud provider give them a workable solution, so they just need to integrate their apps with some agent for shipping the information.

    For others yet, throwing the requirement over to some other team who's supposed to provide such platform components for them is also a possibility.

  • Show HN: Open-source APM with support for tracing, metrics, and logs
    8 projects | | 5 Sep 2022
    This seems like a pretty cool project!

    Currently using Apache Skywalking myself, because it's reasonably simple to get up and running, as well as integrate with some of the more popular stacks:

    I do wonder how ClickHouse (which Uptrace uses) would compare with something like ElasticSearch (which is used by Skywalking and some others) and how badly/well an attempt to use something like MariaDB/MySQL/PostgreSQL for a similar workload would actually go.
