It is extremely frustrating to deploy a workflow only to have no matches due to a typo or not fully understanding the shape of logs that are actually generated on the device.

Enter the workflow debugger. This is the culmination of a ton of work, tying together our various systems into a unified real-time debugging experience driven directly from the browser. Just watch the video. Your 🧠 will explode. Shipping shortly. 🚀

is the difficulty of understanding whether workflows (the finite state machines we send to clients) are actually going to match the expected event sequence once deployed.

Starting today, Capture has you covered for ALL of your mobile obs needs, from the 0.01% of crashing sessions, to the 99.99% of sessions that are crash free but not converting due to app bugs, performance issues, and who knows what else.

Matt Klein
@mattklein123.dev

If you are struggling to solve your non-crashing app issues with a legacy solution that was never built to scale to 100% of sessions, just the 0.01% of crashing sessions, Capture is a one-stop shop and has got you covered. Let's talk! 🚀

Matt Klein
@mattklein123.dev

Yet, up until recently, crash reporting *was* the lingua franca of mobile obs, even though in mature apps over 99.99% of sessions are crash free! This is because, frankly, mobile obs is ridiculously hard, and without local storage and real-time control I would argue impossible to do well.

Matt Klein
@mattklein123.dev

Capture's lack of built-in crash reporting has meant that though customers love the product, it requires an additional solution to provide crash reporting capabilities. And let's be real, no one likes multiple tools.

Matt Klein
@mattklein123.dev

When we launched Capture 1.5 years ago, we fundamentally changed mobile observability by coupling local storage with real-time control. As we like to say, get 1000x the data when you need it and none when you don't!

All too often beautiful UI is an afterthought in infrastructure tooling. This is a miscalculation as users of these tools are drawn to exceptional design just as much as users of consumer products.

As a result, "tail sampling" is still expensive, and the total trace duration is usually short. None of these downsides apply with @bitdrift.io Capture's real-time control and local storage. Sessions can be hours or days long, and the capture decision is based on dynamic state machine execution.

Matt Klein
@mattklein123.dev

With this solution you will be able to capture sessions and performance tracing based on arbitrary matching criteria, and update that criteria in real-time, getting you the traces you need to iteratively debug performance issues all without a single code deploy. Can't wait to ship this! 🚀

Matt Klein
@mattklein123.dev

Traditional tracing requires some type of sampling to control volume and cost. "Head sampling" is the simplest and just decides at the beginning of the trace whether to capture it or not. Thus sampling does not have any trace specific context.

Matt Klein
@mattklein123.dev

"Tail sampling" is more sophisticated and decides at the end of the trace whether to capture (based on observing an error or some other indicator). Without real-time control and local storage, this requires sending *all* data to some intermediate buffer where it can be held to make a decision.

Matt Klein
@mattklein123.dev

I can't overstate how ridiculously cool and powerful this is. You do not need to know what durations you want to measure ahead of time. You can simply log, and then figure this out after the fact.
