OpenSearch Metrics

# Derive metrics from aggregating OpenSearch query results
[[inputs.opensearch_query]]
  ## OpenSearch cluster endpoint(s). Multiple urls can be specified as part
  ## of the same cluster.  Only one succesful call will be made per interval.
  urls = [ "https://node1.os.example.com:9200" ] # required.
 
  ## OpenSearch client timeout, defaults to "5s".
  # timeout = "5s"
 
  ## HTTP basic authentication details
  # username = "admin"
  # password = "admin"
 
  ## Skip TLS validation.  Useful for local testing and self-signed certs.
  # insecure_skip_verify = false

    ## measurement name for the results of the aggregation query
    measurement_name = "measurement"
 
    ## OpenSearch index or index pattern to search
    index = "index-*"
 
    ## The date/time field in the OpenSearch index (mandatory).
    date_field = "@timestamp"
 
    ## If the field used for the date/time field in OpenSearch is also using
    ## a custom date/time format it may be required to provide the format to
    ## correctly parse the field.
    ##
    ## If using one of the built in OpenSearch formats this is not required.

    ## Time window to query (eg. "1m" to query documents from last minute).
    ## Normally should be set to same as collection interval
    query_period = "1m"
 
    ## Lucene query to filter results
    # filter_query = "*"
 
    ## Fields to aggregate values (must be numeric fields)
    # metric_fields = ["metric"]
 
    ## Aggregation function to use on the metric fields
    ## Must be set if 'metric_fields' is set
    ## Valid values are: avg, sum, min, max, sum
    # metric_function = "avg"
 
    ## Fields to be used as tags.  Must be text, non-analyzed fields. Metric
    ## aggregations are performed per tag
    # tags = ["field.keyword", "field2.keyword"]
 
    ## Set to true to not ignore documents when the tag(s) above are missing
    # include_missing_tag = false
 
    ## String value of the tag when the tag does not exist
    ## Required when include_missing_tag is true
    # missing_tag_value = "null"
