# Core Monitoring KPIs

### **Overview**

The *Core Monitoring KPIs* is a Certified Product Point Template for [Power Conversion Systems](/product/docs/power-conversion-system-pcs) that defines required normalized real-time performance calculations that scale, or transform several of the points in the [*Core Real-Time Calculations*](/product/docs/core-real-time-calculations-pcs). These points are required for the Bazefield installation to function properly across all core applications.

These calculations specifically translate OEM-specific signals into consistent indicators of operational state, availability, communication status, and event conditions. By abstracting vendor-specific complexities, the *Core Monitoring KPIs* enables unified fleet monitoring, reduces configuration overhead, and supports consistent reporting and alarm management across heterogeneous [power conversion systems](/product/docs/power-conversion-system-pcs) technologies.

The Core Monitoring KPIs template defines 17 interval-based calculations for Power Conversion Systems. These KPIs aggregate real-time data into 5-minute and hourly metrics for energy production, rack health, and data quality monitoring.

### **Template Definition**

The *Core Monitoring KPIs* is defined below. Calculations are one of the following types:

- **Scale Equations** — Algebraic or logical manipulations of input data done on the [Bazefield edge buffer](/product/docs/edge-buffer)
- **Online Expressions** — Algebraic or logical manipulations of input data done on the central Bazefield data engines (typically on a [storage node](/product/docs/storage-node)). Similar to scale equations in purpose, but done in the centralized architecture.
- **Interval Expressions** — Algebraic, logical, or advanced manipulations of input data done within a pre-defined aggregation interval (e.g. 5 minutes, 10 minutes, 1 hour, etc). These are typically done centrally on a [storage node](/product/docs/storage-node).

Details on the Point Names, Descriptions, and Types are below.
