The histogram regression alerts have some relatively stable regression detection, we might be able to lift something off from there?
Georg, can we simply add a regular histogram on the client for the length of the uncompresssed payload? Then we'd get alerting for free.

Yes, but that wouldn't cover the "core" ping (which has a really constrained set of data points, bug 1249343 will request adding that to the budget monitor). It would also be nice to not have to trust the clients and monitor the actual incoming data, including meta data / headers. We do have some "opt-in" measurements already for "too big" pings on the Fx Desktop (TELEMETRY_PING_SIZE_EXCEEDED_SEND, TELEMETRY_DISCARDED_SEND_PINGS_SIZE_MB), we could add more fine-grained ones and request making them opt-out.
:trink and :gfritzsche - does the recently-deployed doctype monitoring solve this use case?

Sadly we won't know what the new average size of the crash ping will actually be until well after the 53 roll-out as the average size continues to increase.
This is great already. Would it be hard to get a per-docType monitor going? AFAICT, currently we can't tell which docType is changing based on this monitor alone.
Component: Metrics: Pipeline → Monitoring & Alerting
Product: Cloud Services → Data Platform and Tools
You can monitor this for any configured docType. Trink, where are the monitored doctypes configured?
