Name
Prometheus Metric Name
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.
