# Scrapes Longhorn's own metrics (volume robustness, node and disk capacity)
|
|
# so the external Grafana can alert when a volume becomes degraded or faulted.
|
|
#
|
|
# Every longhorn-manager Pod serves /metrics on its `manager` port (9500)
|
|
# behind the longhorn-backend Service. A VMServiceScrape scrapes each Pod
|
|
# behind that Service, so metrics from managers on both storage workers are
|
|
# collected, not just whichever one a load-balanced request would hit.
|
|
#
|
|
# This lives in the victoria-metrics wrapper chart rather than the Longhorn
|
|
# app because it is monitoring configuration, and it depends on the
|
|
# VMServiceScrape CRD installed by this chart's operator. Sync wave "1" makes
|
|
# Argo CD apply it only after that CRD exists on a fresh install.
