I gave up on self-hosted Sentry (2024) (bugsink.com)
In the early 2010s, I was a big fan of Sentry. It was a great tool for tracking errors in web applications. At the time, I was making software for law firms, so sending error reports to a third-party service was out of the question, I needed to host it myself. So I did.

Some notes on Grafana Loki's new "structured metadata" (utoronto.ca)
Grafana Loki somewhat bills itself as "Prometheus for logs", and so it's unsurprising that it started with a data model much like Prometheus.

Ask HN: What do you run instead of Datadog? (ycombinator.com)
Datadog has turned into an ever loving piece of shit. I am sick of their sales team grabbing us by the ankles and "Accidentally" charging for services we don't use. Now, this morning they changed something with their AWS integration that is causing 10X the API calls against our accounts (and thus, 10X guardduty costs on our end analyzing those API requests).
