Prometheus cannot scrape from prometheus-exporter-plugin-for-opensearch

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):
OpenSearch 2.9.0
Plugin Version 2.9.0

Describe the issue:
I have installed opensearch plugin prometheus-exporter-plugin-for-opensearch
I cannot see metrics from curl and prometheus does not scrape metrics.
Let me know how can i solve the problem

Metrics are directly available at:
http(s)://{opensearch-host}:9200/_prometheus/metrics
Is it right? {opensearch-host} = opensearch-cluster-master.{namespace}.{cluster}

Configuration:

  1. Opensearch
    plugins:
    enabled: true
    installList:
  1. Prometheus
  • job_name: opensearch
    scrape_interval: 10s
    metrics_path: “/_prometheus/metrics”
    static_configs:
    • targets:
      • opensearch-host:9200
