CPU Usage of Specific Process

[prakash1243 (Mike)]

Hi-
Am trying to get the Maximum aggregated value for a specific process using Ruby Client. Here is the query I created:

def get_process_cpu(hostname)
  begin
    res = @client.search index: 'metricbeat-*', body:
        {
            "size": 0,
            "aggs": {
                "1": {
                    "max": {
                        "field": "system.process.cpu.total.pct"
                    }
                }
            },
            "query": {
                "bool": {
                    "must": [
                        {
                            "query_string": {
                                "query": "metricset.name: process",
                            }
                        },
                        {
                            "match": {
                                "beat.name": {
                                    "query": "#{hostname}",
                                    "type": "phrase"
                                }
                            }
                        },
                        {
                            "match": {
                                "system.process.name": {
                                    "query": "metricbeat.exe",
                                    "type": "phrase"
                                }
                            }
                        }
                    ]
                }
            }
        }

But, I think am getting the max percentage among all the processes not specific to metricbeat.exe... Could some one please have a look into the query and let me know if any thing wrong. Thanks !
