# Citrix Metrics

> The Citrix Presentation Manager metrics PerformanceGuard collects, at session start and during the session.

Product: PerformanceGuard — a separate CapaSystems product; do not apply this page to any other.

This section explains the Citrix[^®] Presentation Manager Metrics that are collected. Some Citrix metrics are collected whenever a Citrix session is started, while others are collected continuously during the lifetime of the session.

Some rules apply to the sessions that PerformanceGuard will collect data for:

- Only sessions running over the ICA protocol will be included
- Only sessions running a published application will be included

This means that a session running a published desktop won't be included in the measurements.
