Sysdig alert on PV firing with unidentified scope #724

@stewartshea

Description

@stewartshea

An [incorrect] alert is firing on PV utilisation with an unknown scope identified, when the scope should be focused on any prometheus metrics that match a specific namespace label.

Example Alert Event: https://app.sysdigcloud.com/#/event-feed?category=alert&eventId=862301847891861504&last=43200
Configured Trigger:

(avg(kubelet_volume_stats_used_bytes/kubelet_volume_stats_capacity_bytes{namespace='[namespace name]'}) by (persistentvolumeclaim) * 100) >= 50: 0

Reported Scope:

instance = localhost:9100
job = node

Actual Scope: prometheus namespace = [namespace name]
