self-hosted VS Exceptionless

This is the point where I will point out that you can self-host Sentry free of charge :) https://develop.sentry.dev/self-hosted/

The people we're concerned about are not the hundreds of thousands of Sentry users, including those that self-host.

We're concerned about people who have taken the software for the purposes of competing directly against us, that hinders our ability to monetize the work. Monetizing the work helps us continue improving the software and distribute it for free use, benefitting those aforementioned real users (e.g. https://github.com/getsentry/self-hosted).

> I mean no slander or disrespect to anyone involved, but there was a DataDog alternative posted sometime in the last few weeks that had a docker-compose with like 15 containers in it.

Reminds me of Sentry: https://develop.sentry.dev/self-hosted/

This is their example docker-compose for self-hosting: https://github.com/getsentry/self-hosted/blob/master/docker-...

It has:

> What should people use?

I recall Apache Skywalking being pretty good, especially for smaller/medium scale projects: https://skywalking.apache.org/

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: https://skywalking.apache.org/docs/main/v9.0.0/en/setup/back...

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: https://skywalking.apache.org/downloads/

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): https://github.com/getsentry/self-hosted/blob/master/docker-...

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: https://github.com/apache/skywalking/blob/master/docker/dock...

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.

Sounds interesting!

Will you compare with qryn? Self-hosted sentry?

qryn.metrico.in/

https://develop.sentry.dev/self-hosted/

yes to the second https://github.com/getsentry/self-hosted/blob/23.4.0/docker-... and only after the embargo is over to the first: https://github.com/getsentry/self-hosted/blob/23.4.0/LICENSE...

I also miss the "good old days" when running sentry was like 3 containers, not the 32 of modern Sentry

We use the self-hosted Sentry application landscape to set up the actual APM or SPM. We'll only explore a small set of features supported by Sentry to preserve the focus of this post. Refer to the documentation for more details.

> E.g does not allow you to define custom metrics to e.g. monitor resource utilization

I think that might not quite be the case in the latest versions: https://docs.sentry.io/product/performance/metrics/#custom-p...

> In addition to the automatic performance metrics described above, Sentry supports setting custom performance metrics on transactions. Custom performance metrics allow you to define metrics (beyond the ones mentioned above) that are important to your application and send them to Sentry.

> For example, you might want to set a custom metric to track:

> - Total memory usage during a transaction

> - The amount of time being queried

> - Number of times a user performed an action during a transaction

> You define and configure custom metrics in the SDK.

Though for my use cases, Sentry's technical complexity is more of a stumbling block, were I to self-host it: https://github.com/getsentry/self-hosted/blob/master/docker-...

Maybe Exceptionless?

We'll get started by signing up for Exceptionless. Note, you can also run this locally by grabbing the source code and following the instructions here. When you have signed up, you'll be prompted to create a new project. As we create the new project, we'll be prompted ot select the type of project. For this choose "browser application":

With Svelte taking a different approach to JavaScript web frameworks, we should explore how (if at all) handling events and monitoring those events works in Svelte. Open-source ❤️ open-source, so we'll use the open-source event monitoring tool, Exceptionless alongside our Svelte app.

Exceptionless is powered by a REST API. When you interact with the dashboard UI, when you use the .NET client, and when you use the JavaScript client, you are interacting with the REST API. It is well-documented, and it can be used without any client libraries. This paradigm makes it simple for developers to create their own wrappers around the API. In fact, we recently started work on building an official Go client for Exceptionless. Along the way, we learned some tips and tricks that may be helpful for others that want to build clients and SDKs in Go that wrap RESTful APIs.
