# Collecting data and metrics

The PingDataMetrics server polls all the monitored servers over LDAP to gather the following data:

* Status of each server

* Alerts emitted by each server

* Performance data exposed in the `cn=monitor` subtree of each server

For a complete summary of the metrics and dimensions that can be exposed through the RESTful Metrics API, see the reference files located in the `docs/metrics-guide` directory. Most metrics have a count, minimum, maximum, and average.
