    • The following table displays the Kafka connector instance value parameters that you can fill in, as needed, when creating a Kafka connector instance.

    Table 1. Connector instance value parameters
    Parameter Description
    bootstrap_servers Set to true to enable debug logs.

    Default: false
    consumer_group_name Limits metric history retrieval to prevent system overload.

    Default: 180 minutes
    topic Adds a small time buffer to ensure no metrics are missed.

    Default: 5 minutes
    Field_mappings Maps field names from Kafka message payload to internal field identifiers.

    For example: - "node": "host" → maps host in message to internal node field. - "value": "value" → maps metric value. - "timestamp": "ts" → maps timestamp field.

    Default: "{ "metric_type": "metric_name", "resource": "mountpoint", "node": "host", "value": "value", "timestamp": "ts"}
    logPayloadForDebug Determines whether to print the raw log payload. Set to true only for debugging purposes, as printing the raw payload quickly fills up the MID Server logs.

    Default value: false
    debug Displays debug messages.

    Default value: false. Specify true to see debug messages.
    max_poll_attempts Number of times to attempt polling Kafka for messages before stopping.

    Default value: 10
    max_poll_records Maximum number of records fetched in a single poll.

    Default value: 5000
    max_poll_retry Number of times to retry polling if no records are returned consecutively.

    Default value: 2
    poll_timeout_ms Maximum time (in milliseconds) to wait during a poll operation before timing out.

    Default value: 60000
