# Understand metrics

import DocButton from '~/components/webkit/DocButton.vue';

After creating applications and functions, you can also count on [Observe](/en/documentation/products/observe/) products to monitor their behaviors and how they're performing.

- [Real-Time Metrics](/en/documentation/products/observe/real-time-metrics/): access to charts with aggregated data to explore behaviors throughout longer periods of data storage.
- [GraphQL API](/en/documentation/devtools/graphql-api/overview/): access to aggragated and raw data via API with customized queries with only the data you request.
- [Real-Time Events](/en/documentation/products/observe/real-time-events/): access to logs with raw data to perform extensive analysis.

## Applications
