Kyma Metrics Collector (KMC) is a component that scrapes all Kyma clusters to generate metrics. These metrics are sent to an SAP-internal tool called Event Data Platform (EDP) as an event stream and used for billing information.
Learn more about functionality and architecture in the Contributor README.
Kyma Metrics Collector comes with the following command line argument flags:
| Flag | Description | Default Value |
|---|---|---|
scrape-interval |
The time interval to wait between 2 executions of metrics generation. | 3m |
worker-pool-size |
The number of workers in the pool. | 5 |
log-level |
The log-level of the Application. For example, fatal, error, info, debug. |
info |
listen-addr |
The Application starts the server in this port to cater to the metrics and health endpoints. | 8080 |
debug-port |
The custom port to debug when needed. 0 will disable the debugging server. |
