Today I had great time at #JCON2025 presenting 'How I Solved Production Issues with OpenTelemetry (And How You Can Too)".
The @jcon.one conference is really cool to join and talk with fellow developers and share thoughts.

Missed the talk? Check the slides, code and more goto.ceesbos.nl/jcon2025

The first challenge is being prepared! Stay tuned!

I totally agree with you. Observability [123].0 is totally useless if you don't learn and act on it. I am also missing talks about that as well.

I gave it it a try in a talk (goto.ceesbos.nl/fiwo) but closing the loop back to my code is for me the most important part of o11y. Learn and act!!

#GrafanaCON 2025 has been announced by @grafana.bsky.social 📣
This reminds me of my own talk back in April, it was a great honour to speak at GrafanaCON 2024 see https://goto.ceesbos.nl/gc24

I am looking for to this event in 2025! See https://grafana.com/events/grafanacon/
Maybe on stage again??

By the way, I was not the only one facing a problem with 503 errors ... already a issue was opened, so I could add my findings to the ticket, hopefully that contributes to a fast resolution of the issue.

If you have lots of new and active users like @bsky.app, I can imagine that the systems are having tough times and upscaling is needed.
I'm curious about how the monitoring dashboards look like these days.

📈 Nice to see the stats at: bsky.jazco.dev/stats
@jaz.bsky.social thanks!
