[−][src]Enum metrics::BuilderError
Errors during receiver creation.
Variants
UpkeepFailure
Failed to spawn the upkeep thread.
As histograms are windowed, reads and writes require getting the current time so they can perform the required maintenance, or upkeep, on the internal structures to roll over old buckets, etc.
Acquiring the current time is fast compared to most operations, but is a significant portion of the other time it takes to write to a histogram, which limits overall throughput under high load.
We spin up a background thread, or the "upkeep thread", which updates a global time source that the read and write operations exclusively rely on. While this source is not as up-to-date as the real clock, it is much faster to access.
