We build all of our groups dynamically off custom properties anyway.
but here is a custom SQL query based off the volume to alert on members of the Firewalls group with less than 10% free disk space.
Customize as appropriate.
WHERE (
(
100-NULLIF(volumepercentused,-2)<10
)
AND
(
nodes.nodeidIN
(
SELECT cms.entityid
FROM containersc
INNERJOINcontainermembersnapshotscms
ON cms.containerid=c.containerid
WHERE cms.entitytype='Orion.Nodes'
AND c.name='Firewalls')
)
)
[comment: the clear condition is not simply the reverse of this]
here is the clear:
WHERE (
(
100-NULLIF(volumepercentused,-2)>10
)
OR
(
nodes.nodeidNOT IN
(
SELECT cms.entityid
FROM containersc
INNERJOINcontainermembersnapshotscms
ON cms.containerid=c.containerid
WHERE cms.entitytype='Orion.Nodes'
AND c.name='Firewalls')
)
)
