Is your feature request related to a problem? Please describe.

kafkametrics reciever only supports one topic metric.

• kafka.topic.partitions

We want to monitor multiple kafka clusters, It will be easier if there is an additional metric dimension for each cluster.

We want to monitor kafka's topic configurations like replication-factor, min-insync-relicas, log-retention settings etc. These metrics will help us monitor and standardise topic configurations across all of our clusters.

Describe the solution you'd like

I propose to support following metrics that can easily be fetched using sarama client.

• kafka.topic.replication_factor
• kafka.topic.log_retention_ms
• kafka.topic.log_retention_bytes
• kafka.topic.min_insync_replicas

Add an optional configuration field to assign cluster alias name.

receivers:
  kafkametrics:
    protocol_version: 2.0.0
    cluster_alias: kafka-ecom
    scrapers:
      - brokers
      - topics
      - consumers
