tt_dram_used_megabytes
Name
Prometheus Metric Name
tt_dram_used_megabytes
Metric Path (tt-telemetry)
Schema:
{hostname}/dram/tt_dram_used_megabytes
Example path:
bh-glx-c09u02/dram/tt_dram_used_megabytes
Description
Host-level sum of DRAM currently allocated by tt-metal across every MMIO-capable chip on this host, in mebibytes (1 MiB = 1024×1024 B), rounded to the nearest integer.
The per-chip values are read from the same per-device shared-memory regions that back tt_device_dram_used_megabytes. Chips whose SHM region is absent (no tt-metal process has touched them) or whose layout version does not match contribute 0 to the sum.
Values
Type: Unsigned Integer
Units: Megabytes (MB) — reported as mebibytes (1 MiB = 1024×1024 B), rounded to the nearest integer.
Allowable values:
A non-negative integer. 0 means no chip on this host has a live SHM region with allocations.
