Staged Disk Alerting

Good afternoon, 

I am in the process of creating staged alerting, but have ran into some problems. My intent is to raise an (ServiceNow P3) alert at 80% disk utilisation and a P2 at 90% utilisation.

Following on from some posts here about creating specific disk alerting profiles, I have disabled Anomaly detection for infrastructure: Disk and created two metric events, one for 80 and one for 90%. They are both Metric Key alerts, using builtin:host.disk.usedPct with the threshold set respectively. The 80% is a Slowdown event type, the 90% an Error event type. 

I can generate the 80% with no problems from a dev server, however when filling a hard disk to greater than 90% for testing, the problems are linked into Multiple Infrastructure Problems and are raised in SNOW as a P3. 

Is there a way to overcome this please?

Hello! 

Yes there is an easy way to accomplish it. When creating the Metric key alert you can select a toggle that says "Allow merge", this will eliminate the behaviour of merging this Events into a single Problem.
