Asynchronous UpDownCounter is an asynchronous Instrument which reports additive value(s) (e.g. the process heap size - it makes sense to report the heap size from multiple processes and sum them up, so we get the total heap usage) when the instrument is being observed.
Note: if the value is monotonically increasing, use Asynchronous Counter instead; if the value is non-additive, use Asynchronous Gauge instead.create/5 |
