How to use the original indicator of Monitoring in the log file of filebeat

[ADiiana]

Just like these data，I want to use cpu time (system, total, user) to calculate the CPU utilization, so I must know the meaning of the three options, thank you very much.

 {
"monitoring":{
    "metrics":{
        "beat":{
            "cpu":{
                "system":{
                   "ticks":174,
                    "time":175
                },
                "total":{
                    "ticks":359,
                    "time":360,
                    "value":359
                },
                "user":{
                    "ticks":185,
                    "time":185
                }
            },
            "info":{
                "ephemeral_id":"4d2ab930-71fe-461b-8c2c-228782c15a25",

                }
            },
            "memstats":{

        },

            },
            "pipeline":{

                }
            }

        }
    }
}
