Cost and schedule performance
Each project's SPI against its CPI. Below either 0.90 line is an exception.

Risk cover
Live risk exposure as a multiple of the contingency left to absorb it.

The vertical rule is 1x, where live risk equals the contingency left to absorb it.
Forecast uncertainty
The P10 to P90 finish range against each project's baseline duration. The tick is the P50 most likely finish; a wide range means the forecast is still provisional.

Exception triggers
Thresholds that demand attention whatever the written status says: CPI below 0.90, SPI below 0.90, Risk exposure above contingency. From the Early Warning and Project Controls references.
