Cumulative Disk Space Alerting

we have F , G ,H drives mounted to the system and monitored in Dynatrace, can we alert only when the cumulative total of disk used of F + G + H goes beyond 90% and not when individual drives go beyond 90%

Hi @O11y_Noob ,

You can create an metric event with a query this

builtin:host.disk.usedPct:filter(and(or(in("dt.entity.disk",entitySelector("type(disk),entityName.equals(~"A")")),in("dt.entity.disk",entitySelector("type(disk),entityName.equals(~"B~")")),(in("dt.entity.disk",entitySelector("type(disk),entityName.equals(~"C")"))))):splitBy()

and set as a threshold above 90%

Hope it helps.

Regards,

Elena
