How can I set up an alert on a Linux host to notify me when disk usage for a specific path exceeds 80%?

How to add alerting for a disk path utilization in a linux host if it is above 80%?

Hi @Arunkumarbnp ,
By disk path if you mean standard paths like /var or so Dynatrace will by default monitor these. You can check and set the thresholds under Settings -> Anomaly Detection -> Disk edge.

If you mean you want to monitor specific file, filesystem monitoring extension would work better here.
You can read about this here:
Filesystem monitoring monitoring & observability | Dynatrace Hub

Or in case you are already in Dashboards or Notebooks and looking at the metric then you can use the graph menu to open up the anomaly detection definition like 

and then set the threshold condition, this way the query is pre-filled
