 Hello everyone, my name is Bartek and together with my event chairs, Austin, Eduardo, Ritchie, we would love to welcome you very warmly into Observability Day here in Amsterdam, both in person and those who are watching us virtually, and you might hear somewhere, you know, that Observability Day is a co-located CNCF KubeCon event deeply focused on what? What we are focused on? Higher observability, yeah, oh, yeah, some, some, yeah, okay, let's do it one more, one, two, three, yes, yes, some energy, it's 9 a.m. though, so I is expected, so tools, so what's the observability? Of course, it's tools and techniques to monitor and analyze troubleshoot your software on clouds and beyond, but that's, and that's not definitely, you know, wrong decision, here, but actually it's much deeper, right? It's a tradition that we started last year in Detroit that is kind of like joining many passionate people from different CNCF projects or different parts of the CNCF and many, many passionate humans together, yeah, and Observability Days was designed to talk about user stories, right, and strategies and how to use those things and automate in the end user space, right, so we are really focused to make sure that users new or advanced are kind of, you know, you know, learning and so you don't, please don't hesitate to ask questions and really network on the break session, this, you know, this whole day is designed for you, so let's propagate some context if you know what I mean, you know, context propagation, no, if you don't know what I mean, you will know, don't worry, there will be some tracing sessions, but why we are here, right, generally we are here because of those amazing projects, right, so if not their work, we wouldn't have much to talk about really, right, we would just have gaps and, you know, the amazing people really is innovating in those communities, you know, in Observability Space, I'm doing this for free and, you know, so we can really enjoy those things today and talk about the solutions, user stories and experiences, so please great applause for the entertainers and communities and, you know, we will hear many talks from maybe experts around those projects, you know, we have, of course, you know, all the Observability Signals we call them, so, you know, metrics, logs, tracing, profiling and much more, right, like we have cost attribution, we have, you know, like much more advanced techniques like EVPF, so all of this is why we are here. And, you know, as I mentioned before, we kind of started this tradition of Observability Day, you know, half a year ago in Detroit on KubeCon North America, so we are building on this momentum and since last time we had a lot of feedback, we, I hope we improved further with diversity, more user centric talks and so on, so if you don't like something or you don't like something today, send us, should us an email, maybe question, maybe feedback, so we can learn more. Great, so what we will see today? We have amazing agenda coming in, you know, we have some project updates in the very beginning, we have some keynote, we have break, we have Prometheus topic, what else? Open telemetry, profiling, then the break, then the AI, telemetry more, lunch, and during lunch we will have a table, talking table, I will give you more information later about that. Then after lunch we have amazing panel with lots of experts from the projects I mentioned or, yeah, around users. We have two talks about observability at scale, we are at the moment where we are running so many things that we need to, you know, think about how to integrate all those things together. We have a break and finally we have more open telemetry, another scale, full stack integration and EBPF and we end and afterwards there will be time to like socialize, have some drinks and there will be networking, yeah, for the evening. So maybe some important information before we start the whole day, you know, remember about code of contact of course, we want to be nice to each other and, you know, create this safe environment for everyone, so make sure you remember about that. There is a new thing, if you need some more accessibility, there is some service that you can download, it's called Viya Worldly and you can scan this code and I will wait a little bit if you want and essentially it will transcript the sessions in maybe your language, so please do that if you want, it's super useful, okay. And if you are sharing, please share on Twitter or Macedon or anywhere, please use our hashtag so we can kind of go back easily to that and folks are recorded so, you know, make sure we are also kind of like including the virtual audience, make sure to join our tag observability Slack channel, I just will use it just for observability day today, so any questions, any kind of ad hoc conversations we can have there. Wi-Fi, hopefully you already are connected and speakers, please come to us or actually in first to AV team if you want to have a mic, otherwise you can use this mic here just fine, but please connect, you know, five minutes before your talk come to connect your laptop. And talk tables, I mentioned that already, during lunch we will have this new way of collaborating and discussion, so discussion, so essentially chat on some topics, so during breaks and we have like couple of them I think too, we will gather the topics, so please go at the back, there will be like a whiteboard or some kind of white paper and we'll just write, you can write down any topics and we will essentially spread topic per table and during lunch you can eat and learn and talk and maybe, you know, help others as well. And of course, nothing happened without any help, we have amazing program committee, so many people helped to make this happen, we have lots of talk proposals, so thank you for that, we have something to choose from, so please, well, applause for those people. And of course, we had sponsors, so thank you Calypcia for Diamond Sponsorship and Datadoc LightStep Open Search for Platinum and Grafana Labs Observe IQ for Gold and we have Live Sponsor Stream as well, so thank you our sponsors. With this, it's time for project updates, so we have like, have some experts from or maintainers from two major projects, coming on stage and discussing like rough update on what happened recently, so please welcome Ricci at the stage first.
