Hi I am using OEM 13c(13.1.0.1.0) to monitor table space sizes. Here is the procedure that I have used
1. Altered the default template by changing the tablespace warning threshold to 80% and critical threshold to 95%.
2. created a incident rule
I am getting alerts from OEM, but not when the tablespaces are at 80%. I got alert when the tablespace is at 88% and then on some at 90%. I am not sure whether am I making any mistake or OEM is not working. Could you please share your thoughts?
Here is the entry from the template

Thanks
