Event transforms based on event class
When an event arrives in the system, you can change values (such as severity). For example, you can make the summary more informative, or change severity according to text within the summary.
Each event class allows for a short Python script to be executed when an event arrives.
A user may want full file system threshold events on /data to be critical. Add the following Python script in the Threshold Transform of /Events/Perf/Filesystem:
if evt.component == '/data' and evt.severity != 0: evt.severity = 5
Like event mappings for event class keys, "evt" and "dev" objects are available in the script of the transform.
