tt_dram_total_megabytes

Metric Path (tt-telemetry)

Schema:

{hostname}/dram/tt_dram_total_megabytes

Example path:

bh-glx-c09u02/dram/tt_dram_total_megabytes

Description

Host-level sum of installed DRAM capacity across every MMIO-capable chip on this host, in mebibytes (1 MiB = 1024×1024 B), rounded to the nearest integer. The value is static for the lifetime of the process; it depends only on which chips are enumerated and their architecture/harvesting.

This metric is the denominator for host-level DRAM utilization (tt_dram_used_megabytes / tt_dram_total_megabytes).

Values

Type: Unsigned Integer

Units: Megabytes (MB) — reported as mebibytes (1 MiB = 1024×1024 B), rounded to the nearest integer.

Allowable values: A positive integer reflecting total DRAM capacity across all MMIO-capable chips on this host.
