> Monitoring of general metrics for the Apollo Configuration Center service is performed by calling the Prometheus
|
|
> interface of the Apollo Configuration Center.
|
|
|
|
## Prerequisites
|
|
|
|
1. Set up the Apollo configuration center according to
|
|
the [deployment documentation](https://www.apolloconfig.com/#/en/deployment/quick-start).
|
|
2. Visit ```http://${someIp:somePort}/prometheus``` to verify if you can access the metrics data.
|
|
For more details, please refer
|
|
to: [Apollo Monitoring Documentation](https://www.apolloconfig.com/#/en/design/apollo-design?id=v-monitoring-related)
|
|
3. Note⚠️: Starting from version 1.5.0, the Apollo server supports exposing Prometheus-formatted metrics
|
|
via `/prometheus`.
