Ceph is by far the best network monitor... I swear, every single mysterious problem on our ceph clusters has eventually been found to be a glitchy switch, router, fibre, whatever.

🚨 #Cephalocon 2025 🦑 is coming to Vancouver on October 28–29! This isn't just a tech conference, it's the global gathering for anyone who lives and breathes #Ceph. #Developers #Operator #StorageNerd You're gonna want in!

I’ll be speaking at Ceph Days Silicon Valley in March. #Ceph is the leading software-defined #storage, and this event is open to everyone, whether you use it every day or just want to see what the hype is about. Hope to see you there! https://t.co/Ky8r1wd0VR
