# Telemetry

Platform9 deploys and operates Ceilometer, aodh and gnocchi to collect, analyze data, display metrics, generate events, and send alarms. This data is exposed in Clarity in four primary locations:

1. Infrastructure -> Host View -> Performance Tab
2. Instances -> Instance View -> Events Tab
3. Events & Alarms -> Alarms Tab
4. Events & Alarms -> Events Tab
