The fill bars were a share of the host's capacity, a sliver on hosts with 80 cores. Each figure now sits beside 24 bars of the last 6 hours (1h/24h per widget), each row scaled to its own peak but never below 1 core or 1 GiB (configurable per widget), so a 0.05-core container reads flat and a bar's height means real load. One grouped date_bin query feeds them. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# Central widget registry. Each entry describes one widget type that can be
|
|
# placed on a dashboard. Plugin widgets declare which plugin must be enabled.
|
|
#
|
|
# "params" is a list of configurable parameters for the widget. Each param:
|
|
# key - form field name (stored in config_json)
|
|
# label - human-readable label
|
|
# type - "select" (only type currently supported)
|
|
# default - default value (int or str determines how it's parsed from the form)
|
|
# options - list of {value, label} dicts
|
|
#
|
|
# "poll" refreshes the cell every monitor poll interval; "poll_seconds"
|
|
# overrides that cadence for a widget whose data moves slowly.
