# Index Service Cross Reference

> A cross-referenced table of the metrics provided by the Index Service as named by various generations of reporting tools. 

See [Index Service Metrics](index-service-metrics.md) for full description of all the Index Service metrics.

The following table lets you lookup a metric name you may know from an alternative supported or legacy reporting tool.
