Meet Sven Großmann at @AgentConf 2026.
He'll talk about observing agent performance, behavior, cost, and security in production, based on Grafana Assistant's rollout to thousands of users.

Had a great session talking about @grafana and how I used #GrafanaLoki to analyse bird activity in my backyard. Thanks for having me @BarcampFL! #bcfl23 #grafana
Was macht eigentlich @grafana? Was ist Observability? Und wie kann ich #SmartCity und Sensor Daten visualisieren. Ein spannende erste Session auf dem #bcfl23
Wer aus der nodes.sh Community benutzt #grafana?

You might wonder what I do besides bug bounty?
Developing great things in @grafana , writing cool blog posts and over all having lots of fun together with my colleagues @ivanahuckova, Gareth and others! #grafana #Loki #observability
At the beginning of every successful data exploration journey, a query is constructed. So, with the Grafana 9.4 release, we are proud to introduce several new features aimed at improving the Grafana Loki querying experience. Check them out here:

This is quite cool! Apparently I submitted less bugs in 2022 than 2021 but nearly doubled up on payouts 🤑
Trying something new this year: instead of a public year in review, we’ve built a private one with more stats and features to help you plan what’s next in your journey. Here is our first iteration: hackerone.com/hacker_dashboa…. More soon. Let me know what you think. Happy hacking!

Grafana Faro is the latest Grafana Labs open source project: a highly configurable web SDK that instruments web applications to capture observability signals for frontend application observability.

Hey Loki users! 👋
We're cooking up a new feature that allows you to run the log part of a metric query and would love your feedback😀
If you're interested in participating in a short 15 min. research study, please contact me on Twitter or reply to this message. Thanks!

During my onboarding at @grafana I developed a datasource to query insights from @Hacker0x01, which was now release at grafana.com/grafana/plugins/….
If you want to see your report/bounty information from HackerOne in Grafana, try the datasource with a free Grafana Cloud instance!

Hi @TPLINK it's 2022 and you still miss to provide tp-link.com/.well-known/secu… . I would like to tell you that:
1. tplinkcloud.com is somehow public code as of NOW. Great ;)
2. Never store secrets in images :) But thanks for it, was too easy.
DMs are open :)

Because #h12204 is going to end soon, I would like to thank @Hacker0x01 and @PayPal for giving me the opportunity to take apart. The event and especially collaborating with @JuhoMyllys and madinmars was great and much fun!
Also big thanks to the awesome triage team! #hackforgood

I just published my writeup for this month's XSS challenge from @intigriti and @TheRealBrenu: svennergr.github.io/writeups…
Whilst explaining SourceMaps, I did not find any CLI tool, which can generate sources from sourcemaps. Thus I developed my own one: github.com/svennergr/originm…
