1779002 - Introduce a new telemetry probe to monitor service worker life time

Status: NEW

(Core :: DOM: Service Workers, enhancement)

Description

[Harveer Singh]

As discussed in Bug1777400, SERVICE_WORKER_LIFE_TIME telemetry probe was not implemented as intended and hence, it was removed in v105. Here, we would like to implement a better version of the same probe 'SERVICE_WORKER_LIFE_TIME' with granularity in seconds rather than milliseconds. After analyzing it, we concluded that milliseconds is probably not of much use for this probe.

Here, we would like to introduce a new probe similar to one removed in Bug1777400 with below requirements:

1. Capture samples for this probe in the parent process (only!) triggered by ServiceWorkerPrivate (or a helper, like SERVICE_WORKER_RUNNING does).

2. The probe name should contain the units (i.e. if in seconds; name should be sufficed with _seconds or something).

3. Max value should be kept at 120,000.
