Dash0 welcomes Polar Signals to the team.
They built the leading continuous profiler for cloud native workloads, with GPU and CUDA support, and created Parca, the open source profiling project behind it.
Profiling will live natively in Dash0, next to traces, metrics and logs.

🔥Flame charts are now GA for all CPU profiles on Polar Signals Cloud.
X-axis = wall-clock time, so periodic GC, phase shifts, and lock contention show up as patterns instead of getting averaged out.
