# Viewing trigger monitoring charts in Serverless Containers

You can monitor triggers using the monitoring tools in the management console. These tools display diagnostic information as charts. [Monitoring](../../monitoring/index.md) collects metric values and displays charts. 

The chart refresh interval is 15 seconds.
