error_step:
type: event
description: >
An event recorded on an error of the quota manager or its clients.
Since errors are usually propagated up the call chain, all such
propagation steps are recorded for an error. This is only active
during specific contexts, in particular during storage
initialization. No dynamic data is included in the event beyond the
This event was generated to correspond to the Legacy Telemetry event
dom.quota.try.error#step.

quotamanager.initialize.repository:
number_of_iterations:
type: labeled_custom_distribution
description: >
This metric logs the count of directory entries iterated within the
QuotaManager::InitializeRepository function for each repository type.
Each instance of this metric is labeled with one of three repository
types: "persistent", "temporary" or "default" (there's also "private"
repository but that should never be iterated by the function).
The main purpose is to track and analyze iteration counts during the
initialization process of each repository type, helping to identify
performance trends or potential inefficiencies across these repositories.
This can provide insight into the impacts of specific code changes,
including potential optimizations or regressions.
