I use datadog for this specific use case. You can log your own metrics through their API, then set up dashboards and alerting based off specific parameters and thresholds. I mainly use it to track web vitals over time to pinpoint problematic releases or assets, but it can be used for any numeric values you wish to track.
I certainly have! Although I can count on two hands how many times I’ve used it, it has proven to be extremely powerful when trying to pin-point changes that introduced non-trivial bugs. Specifically if the time-span of when the bug was introduced it is very useful to quickly sift through commit history.
