Configure a MongoDB exporter to generate Prometheus metrics

Use the recommended Percona MongoDB Exporter to export MongoDB metrics in Prometheus format.

To configure a MongoDB exporter, complete the following steps:

1. Run the following command to start the Docker version of the exporter:

   Copy

   docker run -d -p 9216:9216 -p 17001:17001 percona/mongodb_exporter:0.39 --mongodb.uri=mongodb://mongodb:17001

2. Use MONGODB_USER and MONGODB_PASSWORD to pass credentials.

   Alternatively, you can use the MongoDB exporter Prometheus community helm chart.
