Today we're launching sensitive data redaction in Mastra observability! Automatically strip out your users’ PII from agent traces:

amazing! definitely really valuable

yeah a really useful implementation of our processor api I think

🚢🚢🚢

awesome

Thanks!

Hi @calcsam I am using mastra with Pg as a store and memory, and noticed a delay about 3 seconds when connecting with PG, Is there anything that might produce such effect so I can revisit and enhance. Thanks

Oft. i see PII redaction maintaining some traceability. Like, instead of "*" it's [EMAIL_1] Wonder how this will effect things like traces -> dataset -> evals

this is a good point. pinging Eric on our team who shipped this

I think my bias is coming from being exposed to this Which i think is a small model for this task

yeah eric and i talked about this and it makes a lot of sense to both of us. will be working on it

Appreciate you two

PII redaction in traces is the compliance win, but the same trace-level visibility is what most teams are still missing on the cost side. If you can strip a field out of every agent trace automatically, you can just as easily tag every trace with what it cost to produce. Is cost attribution on the observability roadmap too, or does Mastra expect teams to bolt that on separately?

we already have that

Good to hear it's already there. Is it opt-in per project or on by default, and does it break down to the step or tool-call level, or just the trace as a whole? That granularity is usually the difference between a nice dashboard and something people actually use to make decisions.

cool! didn't SensitiveDataFilter exist before too? what's new in this release 👀

yeah, but we never actually announced it lol

@mastra Yes having placeholders for redacted inputs is useful for maintaining context, for the agent receiving the user prompt and the downstream processes (eg. Observability, updating evals from real traces)

What we use for redaction?
