How to create a Splunk alert for when storage on host reaches 75%?

[majilan1]

I need to create a Splunk alert that will trigger when storage on /vi/vip_pdh/00d for a host reaches at least 90% capacity.

index=A sourcetype=B   /vi/vip_pdh OR /var/log  earliest=-2h

| eval UsePct=rtrim(UsePct,"%")

| stats latest(UsePct) as UsePct by MountedOn host.

Just a Slight correction, I want to monitor both /vi/vip_pdh and /var/log.

Thanks!
