Module view 

Front-end helpers shared by the TUI and the GUI: graph history, process table sorting/filtering joined with GPU usage, and small naming helpers.

Nothing here depends on a UI toolkit.

Structs

Alert

A condition on a host that needs attention, for overviews.

History

Fixed-size history of samples, newest last.

MetricHistory

Graph histories of one host, updated from each snapshot.

ProcessQuery

How the process table is filtered and sorted.

ProcessRow

One row of the process table: the process plus its GPU usage.

Enums

GraphSpan

How much time the graphs cover.

Severity

How urgent an Alert is.

SortKey

Columns the process table can be sorted by.

Constants

HISTORY_LEN

Number of samples kept for graphs: over an hour at the default interval of 1 s, and wider than any realistic terminal in braille dots (2 samples per cell).

LHM_HINT

Shown where the CPU temperatures go when LibreHardwareMonitor cannot be read (Windows; see Snapshot::lhm_error).

Functions

alerts

alerts_with the default thresholds.

alerts_with

Conditions in snapshot that need attention, most severe first: storage errors and failing drives, degraded RAID, full filesystems, hot CPUs, GPUs and drives, judged by limits (0 turns a threshold off).

default_interface

Picks the physical interface with the most traffic so far.

is_virtual_interface

Returns true for container bridges, veth pairs and loopback, which are skipped when choosing and listing interfaces.

lhm_help

Explanation behind LHM_HINT, given the reason it could not be read.

process_rows

Processes of snapshot after filtering and sorting, joined with GPU usage.

signal_name

Name of a signal as shown to the user.
