# Helm 3

MongoDB Server Connection

To use the chart, ensure the mongodb.uri is populated with a valid MongoDB URI or an existing secret (in the releases namespace) containing the key defined on existingSecret.key, with the URI is referred via existingSecret.name. If no secret key is defined, the default value is mongodb-uri.

If the MongoDB server requires authentication, credentials should be populated in the connection string as well. The MongoDB Exporter supports connecting to either a MongoDB replica set member, shard, or standalone instance.

Service Monitor

The chart comes with a ServiceMonitor for use with the Prometheus Operator. If you're not using the Prometheus Operator, you can disable the ServiceMonitor by setting serviceMonitor.enabled to false and instead populate the podAnnotations as below:

podAnnotations:
  prometheus.io/scrape: "true"
  prometheus.io/port: "metrics"
